How are you doing? Studying lots? I think you are going to do great this time. Like Tony said, examiners do not like to fail anyone, they just want to see good pilots. Now you know what to expect and you can just go in and show him what you know.
As far as the transition, think of it as a new plane that you can fly. Don't be in a rush to get to the test. Go when you feel really comfortable, think of the extra time as training that you would have done regardless if you were a Private Pilot or not.
Keep us posted, and if you have any last minute questions
