Random solving feels good, but hides weakness

Random MCQs can create the illusion of productivity. You stay busy, but you do not always know which chapter is weak or why your score is unstable.

Chapter-wise practice makes improvement measurable because the performance is tied to a specific concept area.

It improves revision quality

When practice is chapter-wise, revision becomes easier. You can return to weak chapters with a clear purpose instead of restarting everything.

That gives students a better path to systematic improvement, especially close to exams.

It supports better analytics

If attempts are tied to chapters, you can track weak zones, wrong patterns, and progress trends. That is much more useful than a vague overall score.

For serious entry-test prep, this kind of structure matters because time is limited and weak topics need to be prioritized fast.
