Hello Dear,

To score 99 percentile you need to score 130-140 marks. first you must solve last 15 years jee mains papers. Evaluate how many marks you are getting in last year papers.

• For MATHEMATICS if you solve EXEMPLAR textbooks(11th, 12th) along with the usual NCERT textbooks plus one more objective textbook(Arihant, FIITJEE study material ,etc.), you will be able to do 80–90% of the paper very well.
• PHYSICS if you solve HC Verma along with the EXEMPLAR and NCERTtextbooks, you will be able to do 75–80% of the paper very well.
• CHEMISTRY in JEE Main & Advanced is set directly from NCERT. So, if you read both the 11th and 12th NCERT textbooks of Chemistry religiously, you should be able to handle the JEE paper astonishingly
