I'm competitive exam student learning Quantative aptitude what should i choose over solving more questions and skipping the one i can't solve or spending hours on one question till i solve it and then moving to next one.
There is a “middle way” between sinking hours into a problem and skipping it completely. Spend a certain amount of time on the problem, document what you did and what your blockers were, and then seek feedback — either from an answer key, a teacher, a peer, or an online forum (like Math SE). If you document what you tried and where you’re struggling, you can more easily use the key to see where you went wrong and get a better reception to your question from a teacher or Math SE.
If you're solving questions that are
- so easy and familiar that solving them requires no thought, or
- so difficult that you can't solve them or solving them requires hours of thought,
then that suggests the educational resources you are using for practice might not be scaffolded very well, and you may benefit from following a more highly scaffolded curriculum.
In order to give more specific recommendations regarding practice material, we'd need to know exactly what exam you're preparing for and what resources you are currently using to prepare for it.
