You also have to do some IR Theoretical Knowledge exams before you can do the CBMIR skill test.
Ground school is by distance learning and is much reduced from the previous PPL/IR studies - only 80 hours now required.
The brush-up course is also much reduced: GTS at Bournemouth, for instance, do one day for each module. I am sure that the other providers do something similar.
By the way, the minimum 10 hours training must be done in an aircraft - not a simulator.
I agree with Mach Jump. It is almost impossible to keep up with the changing rules. My job involves me referring to Part FCL, CAP804 on almost a daily basis and changes still catch me out sometimes.
