hey i am pursuing b.tech from an average institute and i am an average grade student and i am confused what to do after btech.

Since you say that you are an average student academically and that you are doing B.Tech from a not so reputed institute, I suggest that few years of working experience immediately after B.Tech would be more beneficial to you. Once you have few years of hardcore working experience you may then decid

After B.tech you have gone with M.tech that is the best choice for u..

best is you go for higher education that can help you getting over this average thing, good luck
