Why hints, not just answers?
Trains real problem-solving
Most doubt apps hand you a worked solution. In the actual exam, you don't get one. JEEHint nudges you forward so you build the muscle of figuring problems out yourself.
Tags your weak concepts
Every question is tagged by chapter, topic and concept — so over time you can see exactly where you're losing marks and what to revise.
