Revisit your revision notes for a quick recapitulation of concepts, formulae, fact based information and definition etc4. In JEE Main few questions could be asked which might be related to practical. Students who have done practical in school will be able to answer. Hence, refer to lab manual or practical notebook to refresh your memory5. Attempt a full length test paper every alternate day i.e. a minimum of 2-3 question paper before JEE Main. Make sure you analyse your attempts, the hits and the misses and the reason for the misses. If you are writing paper based JEE Main then attempt paper based test and if you are going to appear in online form then your practice must be in online form.
