Speed and Accuracy Under Time Pressure
This domain is about technique rather than new mathematics. In a timed numerical test, the constraint is time, so the winning strategy is to bank easy marks quickly and avoid getting stuck. Work in passes: sweep through the paper answering everything you can do in under a minute, then return to harder items.
Build a small toolkit of mental shortcuts: multiplying by 5 is halving then ×10; multiplying by 25 is ×100 then ÷4; percentages like 15% can be found as 10% plus half of that. Learn to estimate answers to two significant figures and compare with the options - often only one is close.
Traps: spending disproportionate time on one question; re-reading long stems repeatedly; and changing a correct answer out of doubt. If a question needs more than about 90 seconds, flag it and move on. Practise under realistic timing so that pace becomes automatic, and review errors by category (misread, miscalculated, ran out of time) rather than just re-doing the question.
Worked example: to find 15% of 240 quickly, take 10% = 24, halve it for 5% = 12, and add: 36. Rule of thumb: if the options are widely spaced, estimate; only compute exactly when they are close together.
