Hey I did psychology this year and received a study score of above 45.
The advice I would have to give would not deviate much at all from the guides on the old forums (which I found very useful)
I also found this thread created by @BriMT in 2018 incredibly useful for brushing up on research methods.
Good luck and if you have any questions I'm happy to answer. I also plan to release my notes for free sometime in Jan, they are currently very unorganised and I need to tidy them up.
