1) Not sure of a specific answer to this, it'll involve a loan from the bank for a certain amount secured and a certain amount unsecured I think.
2) I think you'd only be able to borrow to the tune of £50,000. So you'd need the remaining £13,000 and living expenses.
3) No, it hasn't been running long enough for them to complete the course.
4) No, they aren't likely to either. When finishing the iCP course, you only have a CPL / IR with 200 hours. On top of that, the chances of you being offered a job just like that, before the end of training are very, very slim. The chances of you getting a job straight out of the iCP scheme is, at the moment, slim. Why? Plenty of cadets from other integrated schools or modular students could well have the MCC / JOC.
That said, you could be in a favourable position with CTC if you do well on the course and if the ATP course is open, you are eligible to apply.
