Dear Applicant the regular admission procedure into M.Tech courses is through the GATE Examination. Now there are few Institutions like Manipal Institute, BITS Pilani, BIT Mesra, Chandigarh University, they conduct their own entrance for admission into M.Tech courses. Now if your college allows you to take direct admission into M.Tech Environment Science course then that is great because generally you need to appear in GATE Examination to be able to take admission.

Good luck!!!!
