how many questions i must attempt to get 90+ percentile?
Greetings aspirant,
Considering your question is related to JEE Mains, one needs to score atleast 69 marks out of total 300 marks to secure atleast 90 percentile in the exam. Although your rank will be par AIR 1,00,000 which would probably nil your chances for getting into NITs, IIITs and GFTIs unless you belong to other category than General and has Home State Quota. You can refer to this link mentioned below to get an idea about rank and percentile as per your score in JEE mains. Link:
