my first cabair brush up course

[atplworry]

I am about to do my first cabair brush up course and was wondering if anyone had any feed back as to what the week is like. I was told on the phone that it was alot of tests and that if I didn't pass I would not be able to sit my exams -is this true, as it is making me quite nervous, even though I am fairly confident I do not like the idea of going all the way there for a week to be told I can't sit them on a bad day or is this a load of crap and it's all lectures. I would be most grateful to know what I'm getting myself into.:{
