Hey all, hope you are all good. I have held my A2 license for 8 years and ride every day and have finally decided it’s time i upgrade to the A license. I am thinking of having a few hours to trim and adjust to the bigger bike prior to mod 1 test (taking the test in the afternoon) then the next day doing the same with Mod 2. my main question is I have moved multiple times in those 8 years and have lost both CBT and A2 pass certificates. I ofcourse have my plastic license stating I have held A2 license for 8 years. Will I need to obtain these other certificates to undertake the test? Would my license be sufficient? If so where can I get these (the test centre has since closed)? thanks all
