A good point to take into consideration though is you pay the course fees, you still have to pay your examination fees at £60 per paper...which is atleast £840 for first attempt on all papers.
You have living/accomodation fees for 6-8 months which can cost just the same as the course itself, the house i'm looking to rent a room in costs £360pm plus an extra £200 for my own food/living etc...totaling to £2520 over 7 months, so by using my example then my additional costs at base line are £3360.
Let us know what you decide.
