Same for me with biology (kinda), I was predicted a C by my teacher which I was actually kinda pissed off with, I wanted atleast a B! anyway I worked soooo hard and apart from the empa, found unit 1 and 2 okay! I ended up getting a C in unit 1, a B in unit 2 and a C in the empa, making a C overall. I need a B in bio for uni, so I'm gonna have to retake unit 1 I think - it's so strange seeing as I found unit 1 okay when I came out?? Its also strange what you said about the aqa psychology, I know lots of people who failed, but I got an A to my amazement..
