- Try looking at the modules they offer and see whether one interests you more than the other.
- If there's a placement year at one or if it's a sandwich course you may benefit better if you want to go into psychology later as you get experience included into your degree.
- Maybe look at the research of the people working there and see if there are any particular people you would want to work with.
I think they're both fairly good universities for psychology; not top 15 really, but probably #15-30, so fairly good.
