Wondering to anyone who is in GEM: How many times did you do the GAMSAT to get into the program ?
Some people take multiple attempts, others get it first try. If you want to estimate how you may do, try your hand at the practice papers. There's three of them available now, the third one should be most similar to the exam as it was just released.
I sat it for the first time in September and got 63. I'm happy enough with this score.
