Reddit reviews The GAMSAT Bible: The Guide to SUCCESS

You are obviously new to gamsat because many other prep resources are mentioned all the time on this reddit and in other student forums. Des is the oldest which is why it probably gets mentioned most but the company no longer exists it stopped years ago and the materials are now considered a bit out of date.

Griffiths Gamsat Review also gets a lot a mention and is regarded as one of the better resources available at the moment.

Gamsat prep and gold standard are the same thing, it also gets a lot of mention although feedback is more mixed than for Gamsat review, but the videos they have on Youtube are useful.
