I have been invited for the IITB test and interview for M.Tech. in Biomedical, but I don't know if I should go. The expense of my going there will be around 15-16k, and I am also not that confident, as I know nothing about the test and interview. I got only 29 marks in the BM GATE, that too some being random wild guesses. What would you suggest to me? Should I go or what?
