There is no fixed number of mock tests that need to be taken. Further, taking mock tests alone can’t help enough to crack the NEET 2023 exam.
If you have 4 weeks (1 month) left for the NEET exam, then the number of slots dedicated to mock tests should be between 9 and 12 per week.
If you have less than 30 days for the exam, then allot 2-3 mock tests per week and slowly increase it to 5 per week.
In the last 10 days, try to attempt at least 5 mock tests along with the revision of short notes and practising problems.
It will be your choice whether to take any more mock tests or not just a day before the exam. You may feel like relaxing and devising the strategy to attempt the paper.
