If your spending over 600 pounds on a cpl test then I think it makes perfect sense to make sure you are up to standard. If you dont do well on a certain part of the course then you will want to make sure you get it right on the test and the only way to do that is spend a few more dollars on another lesson and nail the problem. I to am being tought by M and I think his teaching is second to none. If he says that i need some more work on something then so be it. Its far more cheeper than a re-test and having to line the nice guys at the CAA with more money!
