Cardiff as an international student

Hello, I am planning on applying to Cardiff as an international student, but I just recently discovered their GCSE grading point system.

Based off this system, id only be getting 25/27 full points as my grades are 999999996 the 6 being in English literature

Do I even bother trying? I really want to go to cardiff med but seeing other peoples posts im not sure if i should waste the UCAS spot on it

For info I got AAAA in AS levels predicted A*A*A*A, 2240 UCAT Band 2
