Hey, I did mine with Durston Elms (Roger) really nice people! Roger doesn't put anyone through who he doesn't think are up to standard. £80 for a 3 hour lesson, which if you've been riding a while like I was, you'd not need too many. For the MOD1 practice, they tend to nip down to AMT (I think) down towards weston zoyland/bridgwater as their surfacing is much better. I passed first time with these guys, with a total of 3 minors. Super friendly people, you might be filmed during riding, to see where you go wrong on anything, which is helpful so you can see it for yourself. Best of luck
