WACE Chemistry Past Papers: Check the Working, Then Practise

WACE Chemistry is on 29 October 2026. This post is about using WACE Chemistry past papers and practice exams to find the mistake you keep making, rather than copying the number and moving on.

Your Chemistry answer is wrong. You look at the solution, copy the number and move on. It is worth stopping for another minute. Where did your working first go wrong?

Find the first incorrect step

Start with the official past papers, checking that the questions fit the current course.

Here is a quick example. You have 25.0 mL of a solution at 0.200 mol per litre. Convert the volume first: 25.0 mL is 0.0250 L. Multiply by the concentration and you get 0.00500 mol.

If you put 25.0 straight into that calculation, you are out by a factor of 1000. Writing the units makes that mistake much easier to catch.

For your next calculation, write the relationship, substitute with units and leave enough working to follow it later. When you mark it, find the first incorrect step. That is the bit to practise.

Explain the chemistry, not the change

The same goes for explanations. If the question asks why something changes, explain the chemical reason. Repeating the change in a longer sentence does not explain it. The Chemistry AI marking page is free for every account until Sunday 1 November 2026 if you want feedback on an explanation.

Go back to the Chemistry notes when you cannot explain the chemistry. If organic naming is the problem, start with the functional groups and IUPAC naming note. Use the syllabus guide to check your coverage against the official SCSA requirements.

Try the flashcards for terms you keep forgetting, then use those terms in a focused question. The 2026 exam predictor is a revision guide, not advance knowledge of the exam.

Fresh practice when you need it

When you need fresh practice, look through the original practice exams. You can inspect one attempt and its access details, or choose another once you have checked the first. Marking and correcting one properly is more useful than rushing through both.

What is free and what is paid

We have put the Chemistry resources together on the WACE Chemistry hub. The WACE notes buyer guide explains what to check when choosing revision notes, too.

The official papers are free. Our original practice exams and worked guides are part of the paid subject pack. Chemistry is A$20 once. Three subjects are A$50 and five are A$60. Check the preview and contents on the pricing page before buying.

Our general WACE preparation video is on YouTube. The timetable discussion is on Reddit and our discussion boards, and there is a general overview of the practice exams and subject offer on Instagram.

If you have drifted into reading about scaling or the WACE ATAR calculator, save it for later. It will not tell you your individual result. Your last calculation can tell you what to work on next.

ATARMAXXING is run by ATM Solutions Pty Ltd, Melbourne, and is independent of SCSA.
