Are you in the UK Ellie? It's the replacement for the old Cycling Proficiency Test. I found my instructor by asking at a local bike shop, but you can also ring your local council and ask for details of cycle training for adults. There's also a Cyclecraft book by John Franklin that I think covers everything.

I wobble on left-turn signals until I've worked up a bit of speed. But not as much as I did.

Hello and welcome!
