You improve speed and accuracy together through timed practice, mastering your basics, and smart exam strategy, not by simply rushing. Speed without accuracy means silly mistakes; accuracy without speed means unfinished papers. The goal is both, and both are trainable.
Practise under timed conditions. The only real way to get faster is to practise with a clock, full papers or sets, in the actual time limit. Your brain and hand learn to work quicker through repetition, just like any skill.
Master the fundamentals. Speed comes from strong basics, knowing formulas, concepts, and common steps so well that you do not pause to think. The better you know the material, the faster and more accurately you solve.
Learn shortcuts and tricks. For numerical and aptitude exams, learn calculation shortcuts and standard approaches. Saving a few seconds per question adds up to minutes across a paper.
Improve accuracy with analysis. After each practice test, review every mistake and why it happened, a misread question, a calculation slip, a concept gap. Fixing recurring errors steadily raises accuracy.
Attempt smartly. Do the questions you know quickly first to secure those marks, and do not get stuck on one hard question. Smart order management makes you both faster and more accurate overall.
One practical tip: Keep an error log of every mistake from your practice tests and the reason behind it. Most accuracy problems are a few repeating mistakes, fix those, and your accuracy, confidence, and therefore speed all rise together.
