I would also endorse the posts recommending IAM courses, 'ilmiont'.

Given your very positive attitude towards driving, you might consider joining the IAM anyway and affiliating to a local group. This would perhaps be your most economical route, allowing you to participate in their guidance sessions in preparation for the advanced test. While it is not 'intensive' as such, as suggested by 'MikeGMT', that may not necessarily be an advantage. As a member, you would also be able to take advantage of the courses that Mike mentioned.

One activity laid on by our local group was driving on the skid-pan, which I found particularly helpful.
