Hi, I commuted from Paignton all last year, I went by train but got used to it after the first few weeks. Its quite cheap as well, £6 return.
After the first week or two and you've made some friends you'll find that because they know you travel far they let you stay over at there places, because the trains stop really early 9:30pm or something. There is a late one that leaves at 11:40pm or something but that will only get you to Newton Abbot. Hope you enjoy your time there it's a really nice place to study.
