At AS I ended with poor grades so worked my socks off at A2 and landed ABC. I did the most work in my C graded subject and it came out worse because I don't feel I focused on A2 modules enough.
My A needed an 85 in Core 4 to A* it but I ended up with a 74, despite my other core modules being at least 92.
My B needed 13 more UMS to get an A, though I was only after ABB, I feel if I improved on this I could get A*AB if I did:
* Core 4
* One psychology module
* 2nd year of my C subject
Is it worth it though? Opinions please. I heard some universities frown upon third year students.
