For memory and attachment I did loads of mindmaps, but it really depends on how you learn. There's quite a few quizlets for Psychology which I find really useful for testing my knowledge of study statistics etc. It's always useful to print off the spec and check you've gone over everything, and I always find it useful to then chat about the stuff I've revised e.g. with fellow classmates or just talking at my mum about Loftus and Palmer etc :P . If you're on AQA then make sure you're really confident on the studies for memory and attachment - know the procedure and the findings for Ainsworth and Loftus and Palmer etc; so many people in my class lost a load of marks in our AS mock because they got the attachment types mixed up!
I think it's a good idea to think of general evaluation points you can use as well (e.g. any practical applications); that way there's less pressure to remember individual research support studies :P
Research methods is a bit harder - I'd suggest just keep doing practice questions. (If you're on AQA their textbook has loads of practice questions at the back of the RM section). Look at past papers as well and try to do those in timed conditions - that'll get you used to planning for essay questions etc, and also for the level of research methods expected .
I hope this gives you some ideas?? honestly the main thing is just to make sure you understand the concepts if you're on AQA and ever want to chat about psychology feel free to PM me!
