I don't think you have worked out some of your extras correctly, eg:-
Cabair £1400 for accommodation, £1200 for food.
That's only £43 per week for a 60 week course!!! More like £125 -150 per week = £7500 - £9000 - if not more.
Oxford £1190 for "food and living costs"
Again, that's only £20 per week.
A lot of your others are similar.
