Paper 3 is your last chance, and that changes the odds. Anything the exam board hasn't tested yet in this sitting is more likely to show up here. Here's your 3-day plan.
One focus per day, building to a timed run. Work it in order.
Ranked from analysed past papers. Start at the top: if you run out of time, you will have covered the most-tested ground.
If circle theorems haven't appeared on Paper 1 or Paper 2 this series, they're a strong Paper 3 candidate, a consistent 4-8 mark topic across every session analysed
Appeared on the calculator papers in every session analysed, often as a 3-4 mark comparison question between two data sets
A recurring statistics topic on the final calculator paper: estimating frequency and drawing bars from frequency density
These two topics are frequently paired on Paper 3: cosine rule to find a distance, bearings to interpret the direction
Multi-step ratio questions combining sharing, money, and comparison appear consistently on the final paper, worth up to 4 marks
Appeared on Paper 3 in the sessions analysed, worth 3-4 marks, a repeated percentage growth question, often set in a real-world money context
Higher only. If vectors haven't appeared yet in this series, Paper 3 is where they're most likely to turn up: 4 marks, usually a geometric proof
Appeared on Paper 3 in every session we've analysed, a dependable trigonometry topic to revise regardless of what else has already come up
PrepWise has a one-page Knowledge Organiser for every topic above. In the final 3 days, use them the same way each time: cover the page, try to recall the method and a worked example from memory, check what you missed, then repeat the next day.
Rules specific to Paper 3. On this paper, structure earns as many marks as knowledge.
By Paper 3, you've heard this twice already, and it matters just as much here. A correct method with the wrong final answer still earns marks. A correct answer with no working can lose them. Write every step down, especially in multi-step problems.
If a major topic hasn't appeared yet this series, it's a reasonable bet for Paper 3, but the exam board doesn't guarantee it. Treat this as a prioritisation tool for your last 3 days, not a reason to skip revising anything else entirely.
Keep the full calculator display through every step of a multi-step problem. This matters even more on Paper 3, where questions often chain 3 or 4 calculations together. An early rounding error compounds through the whole answer.
When asked to compare two box plots or two data sets, you need a written comparison ('the median for Class A is higher than Class B, and the interquartile range shows less spread'). Numbers alone without an interpreting sentence lose marks.
Bearings are always three digits, measured clockwise from north. A common mistake is measuring anticlockwise or forgetting the leading zero (writing 45° instead of 045°). Both lose marks even with correct working.
The errors examiners see most on this paper. Each one is an easy mark you already know how to keep.
Assuming a topic 'won't come up' because it appeared on an earlier paper this series → The spec is retested regularly. Treat every topic as possible, but prioritise your last 3 days towards topics that haven't yet appeared this series
Giving numbers only for a 'compare' question, with no written sentence → Always add a short sentence interpreting what the numbers mean: which data set has the higher average, which has more spread, and why
Losing track of units across a multi-step problem, especially with compound interest or ratio → Write the unit next to every number as you go, and check your final answer's unit matches what the question asked for
Measuring a bearing anticlockwise, or without the leading zero for angles under 100° → Always measure clockwise from north and give bearings as three digits: 045°, not 45°
Confusing enlargement scale factors, using a negative or fractional scale factor incorrectly → Remember: a scale factor between 0 and 1 makes the shape smaller, and a negative scale factor flips the shape through the centre of enlargement
