I revised for two days before PSYA3 and think I got 100% again (I did in Jan PSYA4) due to the really low grade boundaries. If you're cramming, like I had too. Use the method of loci to learn names (memory palace technique), and then remember you pick up most of the marks from evaluation and application. If you can talk about a few theories, and most of them are transparent across the bored, for example, you can talk about social learning theory in most psychological approaches, then evaluate it like a crazy man for the most marks. In evaluation, include:
Experiment type, weaknesses and strengths, ie. Lab, field, observational
Is the research ethical?
Is it a questionaire, weaknesses?
Are the participants representative of the general population?
Is it an emic construct, hence used as an imposed etic?
Are they volunteers and so a personality trait which may affect validity?
Are they providing socially desirable answers?
Are there any order effects?
Are there any demand characteristics?
Did they give informed consent?
Is it an interview, and so may not tell the truth (same with questionaire)?
Is it reliable, ie, sample size?
Is it reductionist?
Is it deterministic?
Is it ethnocentric
Is it geynocentric?
Is it androcentric?
Is it correlational, and so cannot dirently infer cause and effect?
Is it based on empirical evidence?
Is it falsisiable, and so a valid theory (Karl Popper)?
Hopefully this helps, just remember; cram the theories, rape the evaluation!
