What do they mean by getting 3A's in A2 at first sit?
I phoned admission office and they said that they accept only one resit per module during the 2 years period. So if you resit biology1 twice and you get A grade at A2, then you will not meet their academic criteria!!
This is worrying of course but how would they know that you have retaken any module 2 or 3 times?
