Aup, I'm 19 and in july i passed my CBT and now drive a Honda CBR125

, but i want to do my full bike test before october. Now i know i can't do the Direct Access because i'm not 21 yet, but i turn 21 within my 2 year CBT and read something about Accelerated Access Scheme, but its not clear to me what i can ride, just sound like a posh name for the CBT test, Can anyone give any more info about what i can do?
Thank You
Michael
