Where TMUA marks leak: the topics to fix first

Not every topic costs you the same. Some are tested a lot and missed a lot, and that's where your revision time pays off most. Here's the order our data suggests.

Fix these first

The lowest-scoring areas are trigonometry and the logic of arguments, both answered right only about half the time, then units, graphs of functions, and geometry.

Trigonometry is the priority for most students, because it's not just badly answered, it's one of the most heavily tested areas, so a weakness there shows up everywhere. The logic of arguments carries the same double cost on Paper 2, which is one reason reasoning is worth focusing on.

Keep these ticking over

At the top of the table are probability, sequences and series, and ratio and proportion, all around two-thirds or better. Keep them sharp, but they're rarely where your next marks are.

How to choose what to revise

Two things matter: how often a topic comes up, and how often you get it wrong. Trigonometry and the logic of arguments are bad on both, so they go top of the list. A topic you're weak at but that barely appears matters less than its accuracy alone suggests. You're not chasing tidy percentages, you're chasing marks per hour.

Good news: students usually read themselves well. The areas people flag as weak at the start (logic, proof, geometry) really are the low scorers. Trust your gut, then check it against timed practice.

Turn it into a plan

Pick your two weakest high-frequency areas, usually trigonometry and the logic of arguments, and give them more than their fair share of the week. Our textbook covers each, and the question bank lets you drill one topic until your accuracy on new questions climbs. Then move down the list. Spreading time evenly just leaves your worst topics as weak as they started.
