Hi Kushal,

If you have not given any entrance exam then you should apply for private colleges that accept board percentage to give direct admission. Though these colleges are not that great in terms of placements and opportunities but since you didn't give any exams, these options would be best for you.
Below is list of colleges that give admission on the basis of your 12th marks:

• SASTRA University
• Amity University
• Bennett University
• PESIT

All the best
