I took the GAMSAT a couple of years ago, and now I'm about to start my second year of medicine at Warwick. I bought these two books from the UCAS website and they really helped me get through the exam, but I no longer need them. The sample questions and practice test are really good to use to see how well your studying is coming together.
I have a copy of the GAMSAT Practice Test book and GAMSAT Sample Questions (2nd edition) book for sale. Both books are the current copies available from the UCAS website.
UCAS GAMSAT preparation material
Would anyone be interested in buying either or both?
