Memorise exercise 6 (S&L) because altho seemingly easy fer tha stoodunt it can be a pig to teach when you start out! If you're in the air on a check out remember to check the stoodunt (CFI) has the ball in balance when assessing they are achieving S&L - the CFI's (and myself now!) have a cunning habit of applying a little rudder just to see if yer playing close attention.
Show that you are commited to teaching and even if you're a knobhead who can't stand people at least pretend that you enjoy being around folks cuz it makes all the difference to a business when a trial lesson punter says "that was super! I wanna fly again!".... most, if not all, of that reasoning is down to the FI they flew wiv.
G'luck!
VFE.
