Well done!
At least you didn't squawk 7700 by mistake like I did on my IMC renewal recently. Though I passed, amazingly. Fortunately the controller who'd just said 'squawk 7000, good day' had realised what I'd done and telephoned the tower at my landing airfield so they could tell me...
Note to self: Remember... 0 is THREE clicks right from 5, not two...
