You already know enough maths.

Usually not. This section tests reasoning using mathematics rather than mathematics itself — the content is broadly secondary-school level, with no calculus and no trigonometry. Most people who score badly aren't missing content; they're caught by time pressure and by questions engineered to punish the obvious approach. The clearest signal is the untimed-versus-timed gap: if you're fine untimed and poor timed, the problem is strategy, and two weeks genuinely can move that.

A genuine content gap, where you didn't know the concept. A careless error, where you knew it and slipped. Misreading, where you answered a different question from the one asked. Running out of time. And right method but too slow. Only the first is fixed by studying more — which is why treating every wrong answer as "revise harder" fixes one case in five and leaves the rest exactly where they were.

Because reviewing topics tells you what you don't know, and the log tells you what you actually get wrong — different lists. In a two-week window there's no time to study everything, so the log is what makes the time targeted. It also surfaces something people miss: careless errors aren't random. Each person makes the same two or three repeatedly — dropping a negative, solving for the wrong variable, mixing up units — and finding yours is worth more than any topic revision.

No — speeding up produces careless errors and doesn't recover the time. You finish by abandoning earlier. The arithmetic is unforgiving: a question that takes four minutes when the budget is two doesn't cost one question, it costs two more, and the ones lost at the end are usually easier than the one that ate the time. The skill is deciding within about thirty seconds whether you have a route, and it's trainable — most people never practise it because they practise untimed.

Using the answer choices, which is legitimate rather than cheating. Backsolving means plugging options into the question, starting from the middle value so a wrong result eliminates several at once. Picking numbers works when the answers contain variables — substitute simple values and see which expression matches. And when the options are far apart, estimation gets there without exact arithmetic. Most people solve as though it were an open-response question, which is the slow route.
