Sunfish,
Congratulations!
The way I figure it, no examiner is going to pass you if you aren't up to scratch - that reflects badly on their rep, so if you passed, you must be doing something right.
I don't see the problem with leaving the chocks in, although I recently heard about someone leaving one wing tie-down on. The lesson must have been spin recovery.
You're right - I hope I can't get an STD from a 152, cos all the ones I've given oral have been awful old sluts.
