If you've passed your class2, it's unlikely that you'll fail class1. (Eye tests are the most likely thing to trip you up, but unlikely.)
Catching a ruler? New one on me. Formal testing of most reflexes usually consists of tapping a tendon with a hammer, tickling things and shining lights in your eyes.
In all honesty, it usually tells the clinician little, but makes him look knowledgeable and helps him justify his bill.
Put a post on here when you pass. :-)
