They do have some good people there. The course was (is?) run by Ray G4FON (of the morse-tutor software fame). He reminded me of the best physics teachers at school years ago - lots of background knowledge so he could expand upon the topics and back them up with real life experience rather than just reading the material from a textbook. He got through the syllabus fine, but was willing to go off on (relevant) tangents and explore things of interest, encouraging discussion of the whole hobby.
The foundation course is one weekend, the intermediate takes two. I much preferred that format to the “an hour a week for 10 weeks” that some clubs do. As a side-interest thing, the course is very close to Greenham Common. We went for a walk over there afterwards. Whilst the runway has gone now, many of the old military bits are still present, including the missile silos which are all open (but behind security fencing with warnings not to enter as they are still a prohibited area). It’s very interesting to see the place that was in the news so often when I was growing up.
