Not studying psychology but a masters student at Sussex, they have tons of psychology placements on the careers site at Sussex so you will have a wide selection of placements at least. Generally it's a really nice uni and you can get into a psych with foundation for sussex if you are worried about grades. Also we do socialise accross unis because Brighton does not have as many or as big societies as we do, the student unions have an agreement that Brighton students can join Sussex societies. Also they have plenty of placements in both therapy orientated and research orientated (only know that because of how frustrating it is how psych orientated they are which in your case it's great but for me not so much lol). Hope this helps a little and best of luck!
