I went to Southampton to do my erasmus. I was studying in Spain and I went to finish my studies in Physics there. In Spain my degree was five years, and maybe that is the reason why I found the level quite low. I didn’t have the chance, but I know that in the last year they do some research studies and there the level is supposed to be quite high.
Apart from that, I found that, compared to Spain, the university was very modern, professors were really good and did everything for the students to learn.
The university had plenty of societies for you to join, many social events, a pub, disco, taxi service to go back home after studying in the library until late or having some beers, I have not seen anything like these in the other universities were I have been.
All in all, I highly recommend this university.
