In NEET and AIIMS most of the questions are direct formula based and one-line theoreticals. There are a few rare gems which force you to twitch your brain muscle for extra firepower. However, in JEE (main) and JEE (adv) most of the questions are more inclined towards conceptual application.

One can argue that JEE (main) has few formula based questions too, however they are limited to 30% per paper and rest of them require more thinking and analysis.

However when it comes to JEE (adv) , the questions are largely based on concepts and often have multiple concepts linked together in a single question.This is rare in case of PMTS.

Also the paper pattern type of JEE (adv) is lot more strenuous than PMTs. You have got the single corrects, multiple corrects ( one having no partial marking, one having partial marking),integer type, matrix matching etc.
