How many mock tests should I take before NEET and how do I actually learn from them?

Quantity matters less than analysis. In the final two to three months, aim for two to three full-length NEET mocks per week under the real 3 hour and 20 minute timing, increasing as the exam nears. The real value is in the analysis, which should take longer than the test itself. After each mock, sort your wrong answers into three buckets: concept not known, silly mistake, and time pressure. For concept gaps, go back to NCERT and relearn; for silly mistakes, note the pattern; for timing, work on which sections you spent too long on. Track your accuracy and your subject-wise scores across mocks to see trends. Also fix your attempt strategy: which subject to start with, how to skip and return. A mock you do not analyse is just wasted energy.
