How to Use Mock Tests Properly (Most Candidates Waste Them)

Many candidates take mock test after mock test, watch their score bounce around, and wonder why it is not improving. The reason is almost always the same: they treat the mock test as the end of the work, when it is really the beginning.

A mock test does two jobs. It shows you what you don’t know, and it trains you to perform under time pressure. You only get the first benefit if you review properly.

Before the test: make it realistic

• Use the real time limit. For a 100-question, 90-minute paper, that is about 54 seconds per question.
• One sitting, no pauses, no phone. Pausing to check an answer turns a test into a study session, and you lose the timing practice.
• Decide your negative-marking strategy in advance. If the real exam deducts marks for wrong answers, switch negative marking on in practice too. Our guide to when to guess explains the maths.

After the test: the review that actually helps

Plan to spend at least as long reviewing as you spent answering. For every question you got wrong, or got right by guessing, put it into one of three groups:

1. Didn’t know it. The fact was new to you. Learn it, and read the explanation so you understand the context.
2. Knew it but got it wrong. You misread the question, confused two similar facts, or changed a correct answer. These are the most valuable mistakes to study, because they are cheap to fix.
3. Ran out of time. You never reached the question, or rushed it. This is a pacing problem, not a knowledge problem.

Count how many mistakes fall into each group. The numbers tell you what to do next:

• Mostly group 1: you need more topic study before more mock tests.
• Mostly group 2: slow down slightly, read every question fully, and keep a “don’t confuse” list.
• Mostly group 3: practise timed sets of 20–25 questions to build speed.

Keep a mistakes list, and actually revisit it

Every question you got wrong should go onto a list you revise regularly. On this site, questions you answer incorrectly are saved automatically to the Mistakes tab on your Saved page, and removed once you answer them correctly. Revising that list for ten minutes before each study session is one of the highest-value habits you can build.

How often should you take full mocks?

• Early in your preparation: one diagnostic mock to find weak areas, then focus on topics.
• Middle phase: short timed quizzes on single topics, several times a week.
• Final two to three weeks: two full mocks a week, each followed by a thorough review.

Taking a full mock every day usually backfires. There is not enough time to review properly, and the same mistakes keep repeating.

Read your score honestly

A single mock score means little; the trend over several tests is what matters. Do not panic over one bad result, and do not relax after one good one. Track your scores on the Test history tab and look for steady improvement.
