Before I took my final ATPL exams last year I did a brush up with Oxford. It was sooo frustrating trying to get on the course, but I did and the instructors were great.
After the ATPL I revisited Oxford and HANDED in an application form to start the CPL/IR.
I NEVER recieved a response. Needless to say I went to a school who appreciate the business and put in the effort with their students (and they're a lot cheaper with no compromise in quality!).
OATS are a shower IMHO!!!
