Since, you have already completed your Diploma course, you can pursue B.Tech in mechanical engineering via lateral entry i.e. taking admission directly in the 2nd year provided that you have scored the qualifying marks depending upon the colleges (generally above 50%).
Some of the colleges are:
Amity University, Noida
Jaypee Institute of Information Technology, Noida
Amity School of Engineering and Technology,
NoidaCollege of Engineering and Technology, IILM Academy of Higher Learning, Noida
Shiv Nadar University, Noida
DIT School of Engineering, Noida
JSS Academy of Technical Education, Noida
Thank you and best of luck.

In my point of view, JSS is a good college in terms of education and placement. You can also see other colleges in Noida if you are interested like Amity University.

In my opinion, you should select VIT, Vellore because, VIT, Vellore is a good institute for computer science and engineering.
