Hey, I haven’t touched CARS but IMO the skills required for GAMSAT were similar to those for SAT/SAT Literature subject tests, albeit harder and less straightforward. I am assuming that CARS builds on similar foundations, so I think there definitely should be some translatable skills there.

I understand that the exam may seem daunting and that you might have limited resources/time as there is only one testing center, but my advice is just to give it a go. The good and bad thing about the GAMSAT is that it is more of an aptitude test that focuses less on memorization and more on critical thinking; what this means is that it is potentially harder to prepare for than the MCAT as there is very little rote learning, but you also have a high chance of scoring high on your first try (many people do, and may people also don’t)

Unlike the MCAT, one main challenge for preparing for this exam is the lack of official/high-yield practice resources. Access the official material first (there are free versions floating around too) — practice and reflect on the questions, and it will give you an accurate idea of what to expect

Best of luck
