How many full-length mock tests should I attempt before UPSC Prelims?

Experts suggest attempting 25 to 40 full-length mock tests to build exam temperament.
While sectional tests strengthen individual subjects, these comprehensive mocks refine time management and elimination skills.
Focus on quality; deeply analyzing 30 tests is better than skimming 60.
Balancing these with Previous Year Questions (PYQs) ensures you align with the actual UPSC pattern while avoiding burnout.
