Intentional Review

A practice score is useful. Knowing why you got it is better.

Getting 15 out of 20 tells you how you performed. Reviewing the questions you missed can tell you what you need to understand. That's why your completed tests should not simply disappear after you see your score.

Question 12 • Topic: Algebra Incorrect Choice
Your answer: B. 3
Correct answer: D. 5
Why? Step-by-step breakdown

Review the question, see the correct answer and read the available explanation so you can understand what you missed.

In this equation, subtracting 7 from both sides gives 3x = 15. Dividing both sides by 3 yields x = 5.

Time Management

Get used to answering against the clock.

The actual examination is timed. Your preparation can be too. Use timed tests to practise managing your time while working through questions.

Stay focused on the question in front of you. The CBT interface presents questions one at a time, with clear navigation and a visible timer to develop your exam stamina and focus.
