Motorcycle and Scooter appreciation

Potentially going to get a 125 geared bike when I turn 17 , anyone know where it's best to do my cbt/A1 , looking to do a advanced rider quali as well if people think it's worth doing it

For CBT anyone but Metroplis. I went with Scootech in Bow who were fine.
For the actual test, Kickstart Rider Training were brilliant.
