you could add the costs of living/food/extras around £5-10 max i believe??
depends on where you live also..some weekly rates for your room at OAT are 150£ per week, 110£ or 100£..so
150x52 weeks that a year has =7800£
110x52 " " " " =5720£
100x52 " " " " =5200£
Of course you have to have in mind that you will not spend the entire 52weeks of a year at OAT.. u will go home for christmas and stuff like that.. but i believe the APP takes around 12 to 18 months to complete so.. that plus food.. it's not cheap. Many students get to hire some places out of OAT after beeing on site a period, my suggestion is that you start looking.. some APP students hire out their hiring house of 4,6,8 students etc during the period they are on the states..many possibilities you have to get it a bit cheaper.. when it comes to thoose prices i can't help u on that..
