Go to a different DMV location that doesn't test parallel parking!
Lol all of them up by me do.. I'm 23 so I can't go through a school. Lol
Have you practiced at all..i like to move my side mirrors as im parking, but good luck =)
Remember keep both hands on the wheel. And just take your time. Since you already been through it once you should know what to do this time around. And i've heard every instructor is different. So Good luck to you. Let me know how u did!
Go practice in a parking lot.
