hello sir.

iam studing in cbse class 12Th now and only 10 months are left for the preparation of iitjee.and i can not afford any coachings.

so you please guide me that how can i crack iitjee with AIR under 1000.

go through ncert books properly without missing a detail.(most important)

manage brilliant toutorials' chemistry study material from some of your friend or relative, learn it and solve it completely.

go through hc verma and arihant phy objective for physics course..

you can counsult rd sharma objective for mathematics......make sure you do not consult more than 2 books for a subject bcs more books you collect more far away you go from your jee rank..

do 10 yrs for all the reputed exams like aieee, IIT-JEE, BITS, dce, vit during last phase of your prepration.....solve as many questions you can(it is key for success in competitive exams)

best of luck !!!

looking forward for your rank
