I'm not from Jersey, but I'm guessing the test is pretty much the same everywhere and it can't hurt you to do extra practice.
1. A lot of people have been known to fail within the first few seconds by crossing the line next to the stop sign. make sure you stop IN FRONT of the line! Also, make sure you make a complete stop and look both ways before you continue.
2. You have 2 minutes to parallel park, they time you with a stop watch. When you're done, you have to be within 12" of the curb. For this part, just stay calm and concentrate. You can practice in a parking lot using a broom inside a trash can as a "car" or you can practice in your neighborhood (there are always cars parked by the curb and you can just park behind them)
3. There's more than enough space to make a 3-point turn
4. You have to reverse straight back (make sure you look in your rear-view mirror
and turn your head to look through the back windshield)
5. Fill out your log book that you got when you passed your permit test!
6. Bring money to pay for your license and enough books, magazines, and/or music to last a few hours at the dmv (for when you're waiting in line..it's always long).
7. Smile in your picture because you will be stuck with it for the next 3 years or so and most of your friends will probably ask to see it and they will laugh at you if you look stupid
Good luck~
