you may want to consider this:
I am about to take my first TP test this Feb 06.
What I gathered over the lessons which has get me pass even my skill is not 100% -
All tested (regardless of TP ot instructor) like to see a decent humble rider. Therefore it is important to behave decent and humble. Don't try to be smart, if the instructor say at this "position" you need to check blind spot, do as told.
Ride slow when near to blind spot, take your time to turn your head to check blind spot. There is no "point" deduct when you ride slow near to "turning bend" but ridding fast, you will have less time to perform a "check blind spot slow head turn action" which is what the TP tester want to see.
Will this is what I think will get me pass, after getting the lesson, only me would know if I have check the "blind" spot.
