Actually if TS got 4A's for A Levels I wouldn't discourage you from applying to UM or USM for medicine.

It may only be for my batch of 2016/2017, but I have friends (scholars who were excluded from their overseas studies due to the budget cuts from JPA) who managed to get UM with 1A* 3A's (non bumi). I on the other hand (bumi) managed to get into USM with just 3 A's. What im trying to say here is do not lose hope in applying to UM and USM just yet.

Now regarding applying to UM I would also like to clarify from experience that UM is quite lax in choosing prospective students to sit for their BMAT test, as I once made an account with a fake IC and they still accepted me. Regarding their English requirements do note they DO NOT accept IELTS and require MUET for their selection criteria.

All the best!!
