Hello Aspirant,
There are no chances for getting into engineering colleges without qualifying any of the entrance exams.
There are very few colleges that takes students of class 12(like toppers) without any entrance exam.But they require donations, and the fees to be paid is vast as the colleges are private.

I suggest you to write any entrance exam (like jee mains, eamcet, mhtcet,etc) or write entrance exams conducted by the private institutions.
Hope this will help you. Good Luck for your career.

Yes you can definitely get in many engineering colleges in India with 60% aggregate marks. That is the minimum required for studying b.tech in many institutions. You should have maths, Chemistry and physics as subjects and 45% aggregate in those subjects. Also you need to give entrance exams held by the particular college or JEE. If you would have been more specific about where you stay. I could have suggested you good colleges there. Hope you find this helpful. Good wishes!

yea okk sure but u will got private clg
