Sir mera 12th me 90 % marks hai aur jee main me 43 marks to kya mera admission rewa gec me kisi tarah se ho sakta hai plzz kuch idea de,
YOU 12TH MARKS IS VERY GOOD BUT IT IS JUST AN ELIGIBILITY CRITERIA FOR ENTRANCE EXAMINATIONS. SO WITH YOUR JEE MARKS YOU WONT ADMISSION IN ANY COLLEGES. ALTHOUGH YOU TRY PRIVATE COLLEGES WHO HAVE THEIR OWN EXAM FOR ADMISSION.
12th board marks will get you nowhere for JEE mains admission into colleges
also if you belong to general category you have not qualified for JEE mains
