yep I was wrong.
You need 200 hours to sit the test. Not to start the course
So you can start the course at 150 hours but only sit the test when you have 200.
You only get the reduction of hours for the IR when you have passed the CPL test (or you did in the old days)
So now its better to do the IR first which is then 55 hours onto the 150 so 205, then 15 hours on top of that for the CPL. But you can start the IR before 150 hours so you can still work it that you can sit your CPL test bang on 200 hours.
