Diploma

Some colleges provide direct second year entry to the Diploma students but most of prestigious colleges across India conducts entrance and give admission only to first year of engineering

You can join if you have studied maths , physics and chemistry in your diploma. you need to get an equivalence certificate

A pass in Class X or its equivalent examination with 50% in each of the subjects with Science and Mathematics student must have studied English as one of the subjects in Class X

I think both available

Go for lateral entry admission in B.Tech first.
