Sorry :-( I don't know much about the GAMSAT. But if you ever need one to one or group tutoring for UMAT, I'm always available. Good luck for GAMSAT though. Hope you do well :-D
For everyone who wants to become a doctor, you all know that umat is just as if not more important than your atar. If anyone who needs any tips/hints or umat tuitions let me know I'll be more than willing to help.
