For some people it helps to just go in and fail the shit out of it if they are that nervous. Then its like, well that's the worst thing that can happen.. and then they kill it the second time. But honestly the drive test is so insanely easy. Look at all the retard Asians on the road today, they somehow made it through and so can you. The only thing that will cause you to fail is nerves. So just visualize how happy you are going to be when you pass right before the test.
