Don't know if you're 141 or 61. But remember that a lot of instructors aren't real high time pilots themselves (at least at the instructing gig) so make sure you get someone really experienced to put you through the ringer with a mock check ride before the actual event. Wish I had. (Ironic how we take people with too little time to make it to a 121 or 135 operation but expect them to do something as critical as teach new pilots how to fly but that's another issue) Try to keep your training in the actual aircraft you will use for the check ride too. I ended up training in two different Arrows with different radio setups and it didn't help simplify things.
By the way. I passed the check ride a few days ago...
