Then the commercial won't be that bad.... Take your time, the most important part of being a "professional" is being ready for everything, that especially includes setting up your maneuvers. Hopefully you don't have 25kt crosswinds! As for the written and practical, if you have your instrument rating, remember how to use all your private pilot calculations (because as a whole instrument pilots are lazy, myself chief among them) because that was the most difficult thing for me. Good luck, and hopefully you don't have a brake lock up on you like I did on the checkride!!!
