No Theory Test but what I know BBDC got a complusary Theory lesson (only 1 lesson) you must take before you can book for your TP. Not sure about the other Driving Centres
Also, if you got the time try to take in the mornings or afternoons (Off-peak hours). Firstly, no much vehicles in circuit and also smaller lesson group so instructors got more time to pay more attention to you. Lastly, not so expensive!!!

I took started my lessons in mid feb this year got me lic in early April. 1 time pass. 2 points only!!! I don't even believe myself!
Lessons is just like your 2B but got additional bumpy course. Longer route in the Circuit.
Because you already have 2B, TP now look for your traffice rules, road confidence and your handling of a larger class bikes (or so I heard....). Should not be a problem unless you did not ride since you got your 2B. Maybe then you need more additional pratice!!
Good luck!
