What usually causes this?
A few well-reviewed mock tests are worth more than lots of rushed ones. You should use mocks to measure readiness, not as your only revision method.
There is no magic number. The better question is whether your mock scores are consistent, reviewed and close enough to show real test readiness.
A few well-reviewed mock tests are worth more than lots of rushed ones. You should use mocks to measure readiness, not as your only revision method.
One good mock score can be luck. Several strong scores, spread across different attempts, are more useful because they show that you are not just remembering a small set of questions.
If you take five mocks and never review the wrong answers, you have not really revised. The review stage is where you find the reason marks were lost.
If your mock scores are stuck in the same range, stop doing back-to-back mocks and fix the weak area causing the pattern.
