Again, I echo what everyone else has said.
The main attraction with CATS was the one week brush up, as there is no way I would have got three weeks off work in one go.
They are very flexible, like other people I am starting with Stage 3, then Stage 2 and finally Stage 1 as it fits best with my requirements.
So far I have found the training materials to be of high standards and instructors are always on hand to answer any questions.
