Moggiee, I do take your point with regards to it being a benefit for the hours building, but the original question was whether it will aid the CPL course. I would suggest pound for pound no.
If you want to ‘use’ your IMC for CPL it’s going to cost you in the region of £3k to get it .
To clarify, yes there are obvious benefits in doing an IMC if you still have your hours building to go, but as an aid to speeding up a CPL it probably won’t help.
