Hello Aspirant,

See Mathematical Induction is the topic from which only 1 questions is asked in JEE-Main usually, hardly in few session it gets two but not more that this and also it is one of the easiest chapter to be completed and have a higher chances of getting full marks at least in these questions, so it is not that important but should be completed for gaining some score very easily.

As we know that now the aspirants are facing their last time preparation before JEE-Main examination so now the solving papers should be the main priority because at this point of time reading of full concepts and chapters won't be the wise strategy so just be focused on solving papers and you can download different previous year's question papers and sample papers of JEE-Main from the link given below  :-
