how I can get more score in jee mains

Dear Aspirant,

There are a few simple things to be taken care of while preparing for this examination. You need to test yourself every week either through mocks or some sample papers. Previous year papers are to be taken very seriously. Solve them all. Balance your 3 subjects. Don't focus much on only one subject. Prioritize mathematics first then chemistry and physics. Eat sleep and breathe JEE. Don't get distracted while doing your preparation. It's like meditation. Meditate for 2 years and you will bear the fruit.
Also, focus more on clarity of concepts. If you have a hold over them you will definitely ace.
