Hello,

Going by the JEE Mains 2021 result, if you wish to score 90 percentile then your marks probably would be lying in the range 58-87. To be honest scoring these marks wouldn't be a herculean task for a student who is well prepared for boards.

If you have basic knowledge of your 11th and 12th standard, then you need to revise again and again the basics and the concepts that are built from them. Read NCERT line by line for scoring good marks in chemistry. You should be thorough with all the concepts in the NCERT in all the subjects and you will get your desired marks. Also practice as many MCQs as possible and give few mock tests so that you can have an idea of the examination.

Though with dedication and hard work you can score better than these much marks in 4 months.

Thank you.
