I scored 64% in 12th board science and i want to pursue b.tech in IT or CS, so which colleges are left with this type of percentage?

There are more good colleges like Amity University ,Sharda University.Apart from that abroad study is also a good option

Deepika Their is a wide road after +12 in science. You have to choose the way in which you have to go. Do not worry 64% marks are also handsome.You give preference to your interest, family background then proceed.Their are several options like BE,B.Tech,BBA,BCA,B Sc etc

You can join any private college or university like MM |University , LPU , Chitkara , Chandigarh
