Hello Asif

If you wish to pursue B.Tech Electronics and Communication Engineering, you must have appeared in 10+2 with Physics, Chemistry and Mathematics as core subjects.

Various engineering exams are conducted such as JEE Main, BITSAT, MHT CET, etc for admission to the Engineering branches.
If you want to apply in any particular college, kindly mention the college name so we can tell you the eligibility criteria and admission process accordingly.

Good Luck!
