if you compare Physics questions of both JEE mains and NEET then you can see that in NEET you need more accuracy and speed than JEE mains.

In general if you consider then Level 1 questions can clear your concepts but i think you should push further till some extent, if you want to. Otherwise Level 1 is ok for NEET

All the best!!

Hi aspirant !

Yes the level 1 questions are enough to score good in physics as they are the easiest ones. Level 2 questions are JEE-ADVANCED level ones . so yes you can do only level-1 questions to score good in neet.
