Probably best if you are a student to pay tuition for abroad as you are now at your home institution, if you are a current student at a university. Whether that be from your pocket, loans etc. Say you go next fall, start working asap and over the summer to get some cash saved up. I think i spent around 1200 or so for one semester for "fun" expenses. Food, drink, travel. I did have some included meals at my homestay, but still ate out a lot. Lunches, some dinners. 1200 bucks over 5 or 6 months can go a long way. You can also blow it real fast if you make a habit of going to expensive places, and there are a lot of them.
