Not in a specific order
1. Location (don't want to be the other side of the country from family, or groups I do where I live now, Also location meaning near to certain venues is important for the course of outdoor actiities, don't want 2 hours in a minbus to get to each practical..)
2. Support. I have a disability and loads of medical conditions so support is really important. I rejected 1 place simpley because when I went on a open day (would not arrange a seperate visit because lots of people is hard because of my disability) they basically would not do anything I currently got at college.
3. People. I had some bad experiences with important people (tutor, or like head of subject if you need them, also student services like for accomodation or finances are useful, as are if there is a doctor or nurse etc..) mainly my tutor at college, so meeting the tutors was quite important to see what their like just as a person really.
4.size of campus. partly disability related really, because I struggle with crouds so a small campus is easier-also harder to get lost at if that's a worry! and hopefully less noisy, party, alchol etc as it's not really in a city either.
5.The course, I wanted a foundation degree so if I hate it im only stuck there for 2 years not 3. Also, my subject is rare so the choice was fairly small for the course.
