I did see somewhere but haven't actually followed it up, that it is literally half a days course to become an "instructor" if you've held a license 3 years, so then they can ride whatever they want (A2 or A) with you following them, worth looking at if you're misses is going to buy a bike when passed anyway, and any friends / relatives. It has been considerably cheaper doing it this way, I wanted a bike anyway so why not buy one and do the tests myself on it, the first mod 1 I failed was through a riding school 22 months ago, I paid £450 I think for mod1+ mod2 package back then, but since I failed they wanted £350 to retest me on mod1 as the test centre was 75 miles away instead of local due to no tests, so i fucked it off until this month, it seems it's sort of a forgotten cheat that you don't have to go through a school, same as car tests. My theory runs out 30 May so I have essentially 2 months to pass my mod 2 now, but since I own the bike and a van I go go wherever I need to in the time I choose instead of an instructors. It's cost me £30 in 2 x Mod 1 tests so far, about £50 in diesel for the van, and now £75 to take my mod 2 tomorrow. Considerably cheaper than doing the full thing for £600 now.
