how to get an overall A* at a level psychology
To score an A* grade for A level Psychology (AQA A) you must score at least 320 UMS out of 400 with an average of 90% at A2. So in basic terms you need to score 90% over Psya3 and Psya4. You can score 85 UMS for Psya3 but then score 95 UMS in Psya4 as that would average out at 90% over the A2 units.
