You should go for B.Tech in computers. It will help you to elaborate your interest in cyber security and cracking of codes.

To get admission, you need to give CAT, MAT, XAT, CMAT or ATMA and then final selection will be done via a GDPI (group discussion and personal interview). These are the main and most important exams to crack not the UPSEE. However, a good score in the UPSEE will definitely help.

No. M.Tech can only be done through students, who are from B.Tech background or have a M.Sc. Degree in Computer application. Moreover, I recommend you directly contact 18001024431, LPU - head office to know if something can be done for that.
