Best thing I could've done

Insane experience and could not recommend more. You make a bunch of international friends, experience education in another country, and can hop on a train to get to another country. I found the modules at Sussex engaging and relevant to my future job. The course load was manageable (much less work than my home uni) and allowed for constant travelling (uni is fairly close to gatwick airport). Sussex is a very international student friendly place, in all of my classes there was a bunch of exchange students. All of the clubs and sports teams had activites and pubcrawls, which really gets you involved in the pubbing culture. Brighton is a vibrant place that is worth the visit.
