DS1 has in teh past struggled with maths, he was in the 4th out of 5 sets for maths at his Grammar school. His GCSE grades weren't earth shattering 2 As 7 As and a B. (As in physics and chemistry)
he is doing AS in Maths, chemistry and physics and (because he couldn't think of anything else, Biology) However since he has started A levels he has really lifted his game .It is entirely possible that he will finish his A2s with 2A*s (chem and phys as he has had 100 UMS in his AS modules) and probably an A in maths (comfortable A at the moment)
The trouble is he doesn't know what to do at Uni.He has since found out that he really should have done further maths to do physics of engineering.
I am sorry it is so vague but he really doesn't know where to start!
