You have 240 MCQs, 4 hours total, and ⅓ negative marking standing between you and a government medical job. The UPSC Combined Medical Services exam tests 19 subjects across 2 papers , thats a lot of ground to cover in limited time.

Ive tested every major medical prep app for UPSC CMS preparation. Most are built for NEET PG and miss the clinical focus CMS demands. Some have huge question banks but poor explanations. Others nail the interface but lack subject depth.
