JEE Main

You have apparently no chances for NIT's or IIIT's even under home state quota!! So better try in good Private institutions! Some even conduct their own entrance tests!!
You may go for VIT/ SRM as top choices if u have good rank in their entrance test!
otherwise go for DAV University or Amity University or any state college! HOPE that helps & answers ur queries!! Feel free to clarify ur doubts!

you should better try for private colleges ,you can give exams conducted by them to get branch of your interest and if you want government colleges then you can look for some of the state government colleges of your state.
best of luck

category n 12th board and percentage?

There is no caste discrimination at JIIT, Noida. You could get sector 128, JIIT Noida on the basis of your 92 marks only!

That's a tough one. You can get CS in sector 128 of JIIT, Noida but getting Sector-62 is way much difficult.

Try Ajay Kumar Garg College, Ghaziabad. It is one of the best private college and takes admission on the basis of marks scored in boards! Jaypee takes in admission based on ranking of JEE. As you told that your marks are low, that would be difficult to get admission in this college.

Yes, you can. Getting sector 62 would not be easy, but sector 128 is in your bag for sure.
