Thanks for all the replies, I really do look forward to doing the driving.
I did find the CPC 2 module kind of challenging but I passed it, just though.
I got 42 out of 50 and the pass mark was 40.
CPC 4 was quite easy, basic understanding of daily checks and security of the vehicle. I did that in a C1 Iveco.
Another question to add, do you just ring up agencies or wait till they advertise?
Thanks again.
