Depends on your state. In PA, if you take the test at the DMV you need to parallel park so if you live here I'd suggest you learn to do that. Other than that, do everything enough to know where all the important buttons and switches are because they normally ask you for that. Other than that, just practice stopping at the white line (when it's there), and making legal turns and stuff. The kind of shit most people get docked for is really simple.
