How to Manage Two HSC Assessments Due in the Same Week

At 6 pm on Monday, you realise your Chemistry report is due Thursday, and your Maths Extension 1 test is Friday morning. Both need several focused sessions. If you spend tonight on whichever feels more urgent, you could reach Wednesday with a nearly finished report and no idea which maths questions you still get wrong.

The solution isn’t to work every spare minute or divide your time equally between subjects. It’s to break both assessments into concrete tasks, estimate how long those tasks will take, identify what needs to happen first, and schedule progress on both before the week gets away from you.

There’s one more rule: a deadline doesn’t change just because your timetable says it should. If the workload genuinely won’t fit, or an important part of an assessment depends on something outside your control, contact your teacher early. An extension only applies once it’s approved.

01The five-step method for overlapping assessments

Step 1: Confirm what each assessment actually requires

Before you start working, check both assessment notifications. You need the real deadlines and requirements, not a rough memory of what your teacher said in class.

For each assessment, record:

• The exact due date and time.
• Whether it is a submission, an in-class test, a presentation, or a combination.
• The required components and submission format.
• The marking criteria and any compulsory sections.
• Any fixed events, such as a supervised lesson or practical component.
• Anything you need from someone else before you can finish.

A task described as “due Friday” might need to be uploaded by 9 am, not midnight. A presentation might also require a separate written component. These details change your schedule.

If you’re unsure what counts towards the assessment, read your HSC assessment notification carefully.

Your goal is to remove avoidable uncertainty before you commit your time.

Step 2: Break each assessment into deliverables

“Work on Chemistry” isn’t a useful task. It’s too vague to tell you what to do when you sit down, or whether you’ve made progress when you finish.

A deliverable is a specific piece of work you can complete and check.

For example:

Notice that the two assessments produce different kinds of progress.

The Chemistry report produces a finished document. Maths preparation produces evidence that you can solve questions accurately and independently.

You can’t prepare for a maths test in exactly the same way you finish a report. Reading worked solutions might feel productive, but it doesn’t show whether you can reproduce the method without help.

For each deliverable, decide what “finished” means.

For example:

• Not “do Chemistry”, but “calculate the required values and save the completed results table”.
• Not “study integration”, but “solve six mixed integration questions without notes, then correct every error”.
• Not “finish the report”, but “compare every required section against the marking criteria and fix missing components”.

This makes it much easier to start, stop, and resume work across a busy week.

Step 3: Estimate the work realistically

Now estimate how long each deliverable will take.

Don’t ask, “How quickly could I finish this if everything went perfectly?” Ask, “How long is this likely to take if I need to think carefully, check my work, and fix a few mistakes?”

A report might require:

• 20 minutes to check the requirements and organise files.
• 60 minutes to process results and create a graph.
• 60 minutes to draft the analysis.
• 45 minutes to write the conclusion and check references.
• 30 minutes to proofread and submit.

That’s 3 hours and 35 minutes of planned work, not “a couple of hours”.

Your first estimate won’t always be correct. That’s fine. The point is to make your assumptions visible so you can adjust the plan before the deadline becomes urgent.

A few rules help:

• Estimate each deliverable separately instead of guessing the total.
• Include setup, checking, corrections, and submission.
• Use a range if you’re uncertain. A task that might take 45-75 minutes should not automatically be scheduled as a 45-minute job.
• Allow a buffer before the official deadline, particularly if the task involves formatting, uploading, teacher feedback, or information that might arrive late.
• Count only the time you can realistically use. Travel, paid work, family responsibilities, sport, meals, and sleep all affect your availability.

A timetable that assumes four hours of uninterrupted work every night is useless if you only have 90 minutes available.

The aim isn’t to predict every minute perfectly. It’s to discover whether the workload can reasonably fit into the time you have.

Step 4: Find the earliest necessary milestones

Here’s where a lot of students lose time.

They look at the due date, work backwards by a few days, and start with whichever task seems easiest. But some tasks cannot begin properly until another task is finished.

These relationships are called dependencies.

Consider a Chemistry investigation report. You can’t analyse a graph you haven’t created, and you can’t create the correct graph until you’ve processed the relevant data.

The order matters:

1. Obtain the required data.
2. Process the results.
3. Create the graph.
4. Analyse the results and explain the pattern.
5. Check the report and submit it.

If you leave the calculations until Wednesday night, your discussion may be delayed too. One late milestone can push several later tasks towards the deadline.

Maths preparation has a different sequence. A short diagnostic set can reveal which topics need the most attention. You can then practise those skills before attempting a timed mixed set.

This leads to an important distinction:

• The deadline is when the assessment must be submitted or completed.
• A milestone is a point by which a necessary part of the work should be finished.

Set milestones before the official deadline. Your report should ideally be ready for its final check before submission day, not still being written when the submission portal closes.

Also identify which tasks you can start independently. If you’re waiting for a teacher to release data, you might still be able to read the criteria, prepare the report structure, or review the relevant theory.

If a critical input is unavailable and you cannot complete the task without it, don’t simply wait and hope. Ask your teacher about the timing and any contingency.

Step 5: Schedule specific progress on both assessments

Once you know the deliverables, estimates, and dependencies, put actual work blocks into your week.

Each block should have a clear action and an expected result.

You don’t need to schedule every minute. Depending on your concentration and the task, a focused block of 30-75 minutes may be useful. Shorter blocks can work well for specific tasks, especially when your available time is limited.

The important part is deciding what you’ll produce before the block starts.

Give both assessments an early start. Even if one is due sooner, the other may need repeated practice or several stages of work.

For example, you could use Monday to complete the first Chemistry milestone and diagnose your Maths weaknesses. Tuesday might contain a longer Chemistry writing block and targeted Maths practice. Wednesday could focus on finishing the report and completing a timed Maths set.

That way, neither assessment becomes a last-minute surprise.

At the end of each session, take a minute to record three things:

• What you finished.
• What remains.
• The next action you will take.

If one task takes longer than expected, update the schedule immediately. Don’t keep following an unrealistic plan just because you wrote it down on Monday.

03When should you contact your teacher?

Two assessments in the same week do not automatically mean you need an extension. Sometimes the tasks are manageable once they’re broken down and scheduled properly.

Other times, the conflict is genuine. You might have two compulsory in-class assessments at the same time, be waiting for information you need to finish a task, or discover that the remaining work cannot fit into your available hours.

The key is to recognise the difference early.

You can probably plan around it when…

• Both assessment requirements are clear.
• You can divide each task into manageable deliverables.
• The necessary information and resources are available.
• Your realistic estimates fit into the available time.
• You can finish the essential work with a reasonable buffer.

In this situation, make the timetable, start both tasks, and check your progress daily.

You don’t need to request an extension simply because the week looks busy.

Contact your teacher early when…

• Two fixed assessment events genuinely overlap.
• You need data, equipment, instructions, or feedback that won’t be available in time.
• Your realistic estimate shows that the required work cannot fit into your remaining study time.
• Illness, caring responsibilities, work commitments, or another significant circumstance has affected your ability to complete the task.
• You’ve started planning and can already see that you are unlikely to meet the original deadline.

The earlier you raise the issue, the more opportunity there may be to clarify requirements or discuss an appropriate arrangement.

If two teachers are involved, you may need to contact both. If you’re unsure who can help resolve a broader timetable conflict, speak to your year adviser or the relevant head teacher.

You do not need to disclose every personal detail to explain that a circumstance is affecting your assessment. Share the information needed to explain the problem and follow your school’s assessment policy.

What should you say?

Avoid sending a message that only says, “I’ve got too much work. Can I have an extension?”

Explain the actual conflict, what you’ve done so far, and what remains.

For example:

Hi [Teacher’s name],

I have [Assessment A] due on [date and time], as well as [Assessment B] on [date and time]. I’ve checked the requirements and estimated the remaining work for each task.

The main issue is [specific conflict, such as required data not being available until a certain time]. Based on the available work periods, this leaves [specific problem].

Could you please clarify [the relevant requirement or timing]? If the conflict cannot be resolved, would an adjustment or extension be possible under the school’s assessment policy?

I’ll continue working towards the current deadline unless an alternative arrangement is approved.

Thank you,
[Your name]

You can adapt this depending on whether you need clarification, help resolving a clash, or an extension. For more guidance, see how to email an HSC teacher for clarification or an extension.

Be specific about the date you could realistically finish if you’re requesting an extension. Asking for a particular, achievable arrangement is more useful than asking vaguely for “a bit longer”.

A deadline you can plan around is not the same as an extension

This distinction is important.

A timetable changes when you intend to complete the work. It does not change the school’s official deadline.

An extension is a change to that deadline that you must request and have approved through the school’s process.

Until you receive clear confirmation of an approved arrangement, work on the assumption that the original due date still applies. Sending an email, receiving an acknowledgement, or being told that someone will look into the request does not necessarily mean an extension has been granted.

Keep working towards the original deadline where possible, and follow your school’s instructions if you cannot submit on time.

If the problem involves serious illness, a family emergency, or another significant circumstance, seek help from an appropriate trusted adult or school support staff as well. You do not have to work out every administrative step alone.

04A 10-minute reset you can use this week

If both assessments are still sitting in your head as two enormous jobs, don’t try to solve the entire week at once.

Spend ten minutes making the next decisions.

• [ ] Write down the exact due dates and times for both assessments.
• [ ] List the deliverables for each task.
• [ ] Estimate the time required for each deliverable, including checking and submission.
• [ ] Identify the earliest milestone for each assessment and any dependencies.
• [ ] Put the first work block for each task into your timetable.
• [ ] Check whether the full plan fits, including a reasonable buffer.
• [ ] Contact your teacher early if it doesn’t fit or an essential requirement is outside your control.

The goal is not to create a perfect timetable. It’s to replace uncertainty with a sequence of actions you can actually take.

Once you’ve done that, the next decision becomes much clearer: either the workload can be managed by changing how you use your available time, or you need to raise a specific problem with your teacher before the deadline is at risk.

05Questions and solutions

Question 1

Your Chemistry report is due Thursday at 3 pm, and your Maths Extension 1 test is Friday morning. You haven’t started either assessment, and you’re feeling overwhelmed. What should you do in the first 20 minutes tonight?

Solution 1

Start by checking both assessment notifications and writing a list of concrete deliverables for each task. Don’t spend the first 20 minutes polishing whichever assessment feels more urgent.

Record the exact deadlines, required components, and submission arrangements. Then identify the first necessary milestone for each task.

For example, the report might need its data processed before you can write the analysis. The Maths test might need a short diagnostic set to reveal which topics require the most practice.

Use the remaining planning time to estimate the work and reserve your first study blocks. You don’t need a perfect weekly schedule yet. You need enough information to start the right tasks in the right order.

The trap is treating anxiety as a reliable priority system. The task that feels most frightening isn’t necessarily the one that needs all your attention tonight.

Question 2

A Physics investigation report is due Thursday at 3 pm. You estimate that it requires four hours:

• Two hours for calculations and graphing, with the graph depending on the calculations.
• One and a half hours for the analysis.
• Thirty minutes for the final check.

Your Maths Extension 1 test is Friday morning and requires three hours of targeted practice.

You are available Monday from 5:30-8 pm, Tuesday from 6-8 pm, Wednesday from 6-8 pm, and Thursday from 4-6 pm.

Construct a workable schedule. Explain how you would protect both assessments and where you would keep some contingency time.

Solution 2

Complete the Physics report early in the week, start Maths preparation on Monday, and reserve part of the remaining time for unexpected delays.

One possible schedule is:

The Physics report receives its required four hours and is completed well before Thursday’s deadline. Maths receives three hours of preparation, starting with a diagnostic and finishing with timed questions and corrections.

The important constraint is the order of the Physics work. You cannot analyse the graph before producing it, so calculations and graphing must be completed before the analysis block.

The available time totals 8.5 hours, while the estimated work totals seven hours. That leaves 1.5 hours for contingency or additional corrections. You don’t need to fill every available minute simply because it exists.

If the report takes longer than expected, use the reserved time first. If the delay is too large to absorb without compromising the remaining work, reassess the plan and contact your teacher if the original deadline is at risk.

Question 3

An English speech worth 40% of its assessment task is due Friday. You estimate that it needs 2.5 hours of preparation, including several rehearsals spread across the week.

A Physics report worth 10% is due Thursday and needs three hours of sequential work, including its final check and submission.

You have 90 minutes on Monday, 90 minutes on Tuesday, 90 minutes on Wednesday, and one hour on Thursday.

Should you prioritise the English speech because it has the higher weighting, or the Physics report because it is due first? Give a schedule that respects both tasks.

Solution 3

Neither weighting nor the nearest deadline should determine the entire schedule. Start the Physics report early because it is due first and has sequential dependencies, while distributing English rehearsal across several days.

The available time is 5.5 hours. The estimated workload is also 5.5 hours, so the plan has no spare time unless some work takes less than expected.

One possible allocation is:

The Physics report receives three hours, including its submission. The English speech receives 2.5 hours, with practice spread across four days.

Why not devote every session to the higher-weighted speech? Because a high weighting doesn’t remove the Physics deadline or its dependency chain. Leaving the report until Wednesday could make it impossible to finish properly if the calculations or analysis take longer than expected.

Why not finish Physics completely before touching English? Because the speech benefits from repeated practice, and leaving all rehearsal until Thursday or Friday would remove that opportunity.

This schedule is feasible on the estimates given, but it has no buffer. If either estimate is uncertain, the student should look for an earlier available work period or contact the relevant teacher if a genuine conflict makes the requirements unmanageable. The weighting is relevant, but it isn’t a substitute for checking the actual constraints.

Question 4

Your assessment notification says that a report is due at 9 am tomorrow. At 8 pm tonight, you realise that you will not finish it on time. You email your teacher asking for an extension, but you receive no reply before the deadline.

Can you assume that you have permission to submit the report the following day? What should you do?

Solution 4

No. You cannot assume that the extension has been approved, so you should continue to treat the original deadline as the applicable deadline unless you receive confirmation of an approved arrangement.

Sending the request and receiving permission are different events. Your email explains the problem and asks for a change; it does not change the assessment requirements by itself.

Contact the teacher as soon as possible, follow your school’s assessment policy, and explain what is complete, what remains, why the deadline is at risk, and when you could realistically finish. If you have already sent a message, don’t assume that silence means agreement.

Continue working towards the original deadline where possible. Follow the school’s instructions if you cannot submit on time, and seek help from your year adviser or another appropriate staff member if you need assistance resolving the situation.

The misconception here is that a reasonable request automatically creates a new deadline. It doesn’t. Planning helps you meet the existing deadline; an extension requires an approved change to it.

Question 5

A student has a Physics report due Thursday at 3 pm and a Maths Extension 1 test on Friday at 9 am.

The Physics report requires five hours of work:

• 1.5 hours of preparation that can be completed before the data arrives.
• One hour to process the data.
• One hour to create the graph.
• One hour to analyse the results.
• Thirty minutes for the final check and submission.

The data must be processed before the graph can be created, and the graph must be completed before the analysis.

The teacher expects to release the data on Tuesday at 4 pm but warns that it might not arrive until 6:15 pm.

The student estimates that the Maths test requires three hours of targeted practice. Their available work periods are:

• Monday, 5-6:30 pm.
• Tuesday, 5-6:30 pm.
• Wednesday, 5-7:30 pm.
• Thursday, 7:30-8 am.
• Thursday, 4-6 pm.

A friend argues that the plan is simple: five hours for Physics plus three hours for Maths equals the eight hours available, so there is no reason to contact the teacher.

Is that reasoning sound? Construct a schedule if the data arrives on time, then explain what changes if it arrives at 6:15 pm. What should the student do now?

Solution 5

The friend’s reasoning is incomplete. The total hours add up, but the schedule depends on when the data becomes available. Because the report’s stages must happen in sequence, a delay can make the original plan impossible even when the total workload has not changed.

If the data arrives at 4 pm on Tuesday, one possible schedule is:

The Physics work totals five hours, and Maths practice totals three hours. If the data arrives on time and every estimate holds, the plan fits exactly.

But there is no spare time.

Now suppose the data arrives at 6:15 pm on Tuesday. Only 15 minutes remain in that evening’s work period. The student cannot complete the planned hour of data processing.

After the data arrives, the remaining available periods are only 15 minutes on Tuesday, 2.5 hours on Wednesday, and 30 minutes on Thursday morning. Together, that’s 3 hours and 15 minutes.

The report still needs 3.5 hours after the data arrives: one hour for processing, one hour for the graph, one hour for analysis, and half an hour for the final check and submission. The student is now 15 minutes short, even before allowing for any additional problems.

The tempting response is to assume that the student can simply work faster or skip the final check. But that ignores the sequential dependencies and the fact that the available hours have already been allocated to both assessments. The student cannot process data before receiving it, and the Thursday afternoon Maths block occurs after the Physics deadline.

The right decision is to contact the teacher on Monday, before the data is due, to confirm the release time and ask what contingency is available if the data is delayed. The student should also complete the independent Physics preparation on Monday and reserve the planned blocks for both assessments.

If the teacher confirms that the data may not arrive until 6:15 pm and no alternative is available, the student should explain the resulting conflict and ask whether an approved adjustment is possible. They should not assume that an extension has been granted, and the original deadline remains in force unless an alternative arrangement is approved.

This is the key lesson: a plan is only workable if the necessary work can happen in the right order, within the time actually available. When a dependency makes that impossible, identify the problem early and resolve it with the teacher rather than waiting for the deadline to arrive.
