Hey guys, I've made up my mind to study in IMU for medicine, all five years done locally since parents could not afford to send me for twinning (a cousin of mine spent 1.5mil to twin in AUS).

However, as I just got my Cambridge AS results today, and was hugely disappointed with 1a,2b,1c, and all which are borderline:

Bio, b, 77
Chemi, b, 78
Physics, a, 86
Math, c, 68

which I may whine all day saying I was having dengue fever during bio and chemi P2 , and missed a huge mark question on math P1. Yet I understand most of it was my fault and so I won't whine so much of it here. (ITS MY OWN FAULT)
So I'm going to push for all A for A2.

But what are my chances of getting into local medicine/dentistry if I get either:
A*AAA
AAAB
ABBB
ABBC
?

And how competitive is it to get into local medicine, since I heard that the twinning program is more competitive.
