I did all my ground school with them end of last year, in 5 days. I couldn't recommend it highly enough. They were excellent. Harrogate is a lovely town as well.
I then carried on my training down south, and contrary to the experience of bose-x above, I requested my docs, and they were with me within a few days.
I've just booked up to finish my training and do my skills with them test this weekend.
