Which are the engineering colleges I may get admission?

At 36 i dont think so you will get admission in any government college. But there is good option for you in private university like VIT, PSG College of Technology, Lovely Professional University. These universities conduct there own entrance test on the basis on which you may get scholarship too.

Colleges which admits a student on basis of entrance score are genuine, always go for those colleges, direct admission colleges are highly avoidable. AICTE is very important, the course shud be aicte approved. dnt compromise ur degree and 4 years for few lakhs. amity is fair enough and i wud suggest
