Hi Lee,
Have you read all of bjkeates's diary? I found it very useful for getting a flavour of what is to come (I'm also on cp53 so I really enjoyed reading it!) I can't remember the exact web address but I believe it is linked somewhere earlier in this thread.
bjkeates - hope you don't mind me referring to your blog but I think its great for people wanting to find out more about the CTC course.
Regards,
G.U.N
