Hi Aridma,

Being an Ex JEE aspirant i think i can provide you better details and information about the scores and about JEE mains exam preparation. See, generally candidates prepare for JEE mains from their class 11th by joining different coaching institutes that will help them in building the concepts. Since the preparation might create a problem among candidates due to its complexity so it is better to understand each and every thing from the beginning with a vision of scoring better life and score.

See, the score depends upon the questions you attempt correctly and the preparation. Scores matters most but it does not define  the capability a student has inside them, the knowledge they have.

My personal advice is not to worry about what rank you will get and will you be able to crack JEE mains or not. You must understand that you need to give your best in the examination by preparing sincerely.

Hope you understand!

Good luck:)
