Just wanted to put it out there but with Psychology exams both AS and A2 it is impossible to predict what will come up. This is because with Psychology everything is potentially a 12 mark, 8 mark or 6 mark question. For that reason never listen to predictions even if it given by teachers. The best thing to do is to do all past papers from 2011 onwards. This is the best way to prepare for the exam. Not only are you aware of how of much each question requires but you also realised that similar questions come up every year with different wording. For example, With Psychology AS the previous year the 12 mark question can be on Social Psychology, this does not mean they won't ask a 12 mark from Social Psychology again. They can do it! If you're in year 12 and think you did not do well (hope you did), when re-taking this module next year do not forget to do past papers!
Secondly, Psychology A2 perditions are bullcrap! Just do every single possible 24 mark essay question that could come up! Get your teachers to re-mark it several times until every essay is over 18 marks.
I wish the best for everyone who does psychology, it really is the best a-level but the hardest too.
