Hi dear,

If you have not qualified eamcet and want to do engineering, then you can seek admission in some private colleges but they may require you to pay donations as you haven't qualified eamcet.Besides this if you have good marks in 10+2 ,it will give you a way to get into colleges.

Otherwise, you can go forward with Diploma courses, then you can apply directly to such colleges without entrance exams but your 10+2 will play a major role in seeking admission for Diploma courses.

Hope this helps!
