I'll have to second the whole "teach someone" the material. Not that my Fiance cares to really hear about it all the time
she still listens, and it allows me to find my weak spots, even in answers I thought I knew. When going through the PTS, use that as a study guide. Example, when you get to the emergencies section...take the time to review emergency procedures, etc.
I guess the biggest issues to take into consideration besides knowing the regs and everything, is to make proper use of the checklists, and just use common sense (ADM). Lastly, just relax. It's the first checkride, so the tension is always there, but just try to relax and everything will be fine.
Best of luck. Make sure to post your result.
