CSCA · The final stretch
What to Revise in the Final 2 Days Before CSCA
Choose what to revise in Math, Physics and Chemistry. Use subject checklists to check key skills, retry mistakes and plan your final two days.
Find my subject checklist
Start with the subjects you are taking.
Use the checklists below to scan the topics. Match them to your recent mistakes, then choose one or two familiar weak areas for today.
- Can solve it → quick check
- Recall the method and try a fresh question.
- Know it, but make errors → repair first
- Fix the missed condition, step, sign or unit.
- Completely new → limit the scope
- Try an accessible basic idea only if time allows.
Your final two-day subject checklists
Go to your subject. Review the topic points, then try the check task for a weak skill. Tick when you can explain it and solve a fresh question without hints.
Mathematics
Read the graph. Choose the model.
For a fresh question on a selected skill, choose a matching exercise from the CSCA Mathematics resources.
One worked check: Function domain
Try one question before ticking the topic
Find the domain of f(x) = √(x − 2)/(x − 5). Write both restrictions before combining them.
Check the method and answer
- The square root needs x − 2 ≥ 0, so x ≥ 2.
- The denominator cannot be zero, so x ≠ 5.
- Combine: [2, 5) ∪ (5, ∞). The endpoint 2 is allowed; 5 is excluded.
Watch for this: Do not use x > 2: a zero under the square root is allowed. Do not forget the denominator restriction.
Retry tomorrow
Find the domain of √(x + 1)/(x − 3). After attempting it, check: [−1, 3) ∪ (3, ∞).
Chemistry
Identify the change. Check the amount.
Choose a matching exercise from the CSCA Chemistry resources to check your calculation or explanation.
One worked check: Dilution
Try one question before ticking the topic
Dilute 100 mL of a 0.20 mol/L solution with water to a final volume of 250 mL. No reaction occurs. What is the new concentration?
Check the method and answer
- The amount of solute stays the same: C₁V₁ = C₂V₂.
- Use the same volume unit on both sides: C₂ = 0.20 × 100/250.
- C₂ = 0.080 mol/L. Dilution increases volume and lowers concentration.
Watch for this: 250 mL is the final volume, not the volume of water added. The equation does not apply unchanged if a reaction consumes the solute.
Retry tomorrow
Dilute 50 mL of 0.30 mol/L solution to 150 mL. Check your independent result: 0.10 mol/L.
Physics
Draw the system. Explain the law.
Use the CSCA Physics resources for a matching question, then check the diagram, law and units in your solution.
One worked check: Net force
Try one question before ticking the topic
A 2 kg object has horizontal forces of 6 N to the right and 2 N to the left. These are the only horizontal forces; its vertical forces balance. Find its acceleration.
Check the method and answer
- Take right as positive. Fnet = 6 − 2 = 4 N to the right.
- Use the net force in Newton’s second law: a = Fnet/m = 4/2.
- a = 2 m/s² to the right. The acceleration direction follows the net force, not necessarily the current velocity.
Watch for this: Do not add the opposing forces to get 8 N, or substitute 6 N alone into F = ma.
Retry tomorrow
For a 3 kg object with 10 N right and 4 N left, with no other horizontal force, check: a = 2 m/s² right.
These are selected revision topics. The CSCA subject syllabus guide covers the full scope, including Academic Chinese if you are taking it.
Turn a checklist topic into practice.
Use this three-step loop for each weak skill you picked. Tick after an independent check; return to it tomorrow.
Try before checking
Write the formula and conditions, or start one question without notes.[3]
Make the correction specific
Find the failed step. Explain it, close the solution, and try a fresh question.[1, 5]
Check again after a delay
Tomorrow, solve a changed-number question without yesterday’s answer beside you.[4]

Fit your selected topics into two days.
Example: about 2½ hours of focused work each day, with breaks. Share the blocks across your exam subjects and adjust them to your available time.
Day 1 · Two days before
Find the gap. Fix the pattern.
- 15min
Choose two repair targets
Pick two errors from recent practice in your chosen checklist topics.
- 50min
One worked example → one fresh question
Fix the failed step; close the solution and solve a similar question. Then take a break.
- 35min
Check independent work; add time if ready
Can solve independently? Try a short timed set. Still need hints? Repair without a timer.
- 40min
Write tomorrow’s retry list
Check answers and note the failed step for tomorrow.
Day 2 · The day before
Retrieve. Check. Finish calmly.
- 45min
Retry yesterday’s errors
No notes first. Review only the step that still fails.
- 40min
Recall formulas and conditions
Write formulas from memory; check conditions, signs and units.
- 30min
A short mixed check
Mix familiar topics and choose methods without chapter labels. Review immediately.
- 30min
Prepare for the exam
Check ticket, local start time, ID and test-mode instructions; leave time for rest.
Set a finish time that leaves room for rest. Set your finish time first. If time runs short, do fewer questions, keep the error review, and leave room for rest.[6]
Use the exam-day checklist to check your documents, setup and test-mode instructions before you finish revising.
Choose your next task from the error
After each check, use the result to choose your next move.
| What happened? | Do this next |
|---|---|
| I knew the method but lost a sign or unit. | Redo the calculation slowly, then check one fresh question using a written sign/unit check. |
| I recognised the topic but could not start. | Study one worked example. Explain the first step, close it and try a similar basic question. |
| I can solve it but run out of time. | Time a small set of familiar questions. Record where time goes: recognising the method, working or checking. Practise that slow step, following the navigation rules of your test. |
| The whole chapter is new to me. | Focus on an accessible basic concept only if it fits your remaining time. Return to familiar, repairable errors first. |
Error note: missed x ≠ 5 → write denominator restrictions first → retry a new domain question tomorrow.[5]
For a Math question you cannot start, the CSCA Math foundation guide helps locate the missing skill; use the preparation guide for a longer rebuild.
Turn one priority into your next practice.
Pick a familiar topic, attempt a short set, and use the result to decide what to retry tomorrow.
Questions students ask in the final two days
What should I revise first in the final 2 days before CSCA?
Check your recent mistakes in the subjects you are sitting.
- Choose one or two familiar skills with a repairable error, such as a missing function restriction, a dilution-volume mistake or a wrong net-force direction.
- Use the official syllabus to confirm scope, then practise and recheck the correction tomorrow.
What should I revise for CSCA Math in the final two days?
Use the Math checklist to review functions, trigonometry, coordinate geometry and conics, sequences and basic algebra.
- Choose the groups where recent questions exposed an error, such as a missing domain restriction or a wrong sequence index.
- Recall the rule, solve one matching question without notes and recheck the corrected step tomorrow.
What should I revise for CSCA Physics in the final two days?
Check motion and forces, work/energy/momentum, electricity and magnetism, then waves, optics and thermal physics.
- Start with a familiar error you can explain: draw the system, choose a positive direction and state when the law applies.
- Use the Physics topic breakdown to understand chapter emphasis while keeping the full syllabus in view.
What should I revise for CSCA Chemistry in the final two days?
Check core concepts, reaction types, amount/concentration calculations, then equilibrium, rates and energy changes.
- For calculations, check the balanced equation, units, solution volume and whether a reaction consumes the solute.
- Use the Chemistry checklist to test the step independently instead of only rereading a formula.
Should I learn new CSCA topics in the final two days?
Only if the basic idea is manageable within the time left.
- A completely unfamiliar chapter can consume the time needed to repair several errors in topics you already know.
- Use a longer preparation plan if much of the syllabus is new.
Should I do a full CSCA mock in the final 48 hours?
Do one only if you have time to review it and it serves a clear purpose, such as practising pacing.
- Otherwise, a short timed set followed by error review is a more manageable final-stage task.
- The CSCA Math mock comparison explains what a mock can show about topic and method coverage.
Do I need to revise all three science subjects?
No.
- Follow the subjects required by your university or programme and shown in your registration.
- This article covers Math, Physics and Chemistry; it does not replace revision for any Academic Chinese paper you are taking.
Are these priorities official CSCA chapter percentages?
No.
- They are PrepPals revision recommendations.
- The official syllabus defines the scope.
- A distribution from a particular analysed paper describes that sample, not a fixed promise for later exams.
What should I revise if CSCA is tomorrow?
Choose one familiar weak topic, retry a few errors without notes and check your exam arrangements.
- Shorten the plan to fit your time rather than sacrificing sleep to finish every checkbox.
- The checklist is a tool, not a completion target.
Is memorising formulas enough for the final review?
Retrieve the formula, state its conditions, then use it in a question.
- For example, dilution keeps the amount of solute constant only when no reaction consumes it.
- A remembered equation is useful when you can recognise where it applies and check the units.
When should I switch from untimed to timed practice?
Add time to question types you can already solve independently.
- If you still need the solution to choose the first step, repair that step before timing it.
- Keep stronger skills in short timed sets and give weaker skills guided practice; different topics can need different tasks.
