Toiletries such as shampoo, soap, toothpaste, deodorant, bogroll and mouthwash shouldn't set you back more than about 10 quid a week. A reasonable burger can be had for about 2 quid and a pizza will set you back about 3 to 5 quid. Meat isn't as expensive as the EU and a steak, chips and salad should go for around 5 quid at current rates.
Good luck with your course...
