I got 61% in 12th and got good rank in jee main. Can I get gov. College in Delhi?

Hello,
Sorry but with this percentage the changes of getting admission into any government college is next to impossible. You aren't even eligible to give entrance exams like jee mains and other government entrance exams because for that you need to have a minimum of 75% as general category student. Moreover getting admission in DU's is also nit possible with thia percentage. However, you might get admission in some private colleges else you can also fill improvement form to upgrade your percentage if you want.
All the best.
Thank you.
