Good stuff. In that case 92.5% comes in as "Bl**dy annoying as it should have been 100%."
Have a chat with the school and if they don't agree, tell them to read LASORS and maybe ring Flight Crew Licensing. The CAA say that the licence cannot be issued and the priveleges of the licence can't be used before your 17th birthday, it doesn't say that you can't do the test.
If they still argue, tell Ted to ring me!
