the digestion and absorption of carbs is unit 2 whereas insulin/glucagon is unit 4 so was really easy to link
you misunderstood me (my fault really i didnt explain it very well... you said that you needed to get something to do with an AEA - is that what step is???
Anyways, he got an offer of either AABb where one A has to be further maths or AABb and a certain grade in the step paper (don't really know anything about this exam but i think you get a number as a grade rather than a letter)... so he doesnt need both. Cuz your amazing at maths you'll get an A in further maths so i can't see you not getting in...
Hopefully uni will be great but i'm a bit worried about the work load
