Hi Nadia,
I'm in my third year of psychology at Uni of Liverpool. I'm currently doing a forensic psychology module. It looks at psychology in the court room, for example eye witness testimony, interview techniques, but also things like offender profiling and psychology in critical situations. I'm really enjoying it.
As for studying psychology in general, you tend to do all the modules the BPS make you do in the first and second year, but you get to specialise in your 3rd year.
I hope that helps, although that was just a bit of ramble from me ha
