One of the features of beekeeping in this country that you will soon find is that there are many ways of doing it. There are many you will meet who insist they have the "one true way" and they will all be different. That's probably the most confusing aspect for beginners. The only way out is getting in a variety of opinions and working out what's best for you.
This forum probably has as wide a range as you'll find in any single place. If you have several local BKA alternatives, try going along to several. They are not geographically exclusive. And they do vary in attitude and interests, local BKAs are all volunteer based so you wouldn't expect any different. What they do provide is a chance to view and talk about bees. Nearly all affiliate to the BBKA (or WBKA, SBKA, UBKA, FIBKA) and membership at both local and national level is far better value than only national.
In the meantime, courses outside local BKAs are still relatively unusual. Let us know how you get on and what it's like. What we have noticed locally is that most of the local BKA who run spring courses have seen numbers peak a few years back and fall back again. If other organisations are making efforts to expand training now, they may find that difficult.
