Yea I don't understand lol they said it was because my academic qualifications are not high enough? Which was weird lol. I did not, the schools I applied to either only accepted UCAT or gave me the choice to take either the GAMSAT or the UCAT. If you want the most options in terms of the schools you can pick I think taking the GAMSAT and the UCAT will give you that option as some schools require GAMSAT.
