I just did it in Clinton last Friday, I did practice the serpentine, and hard braking but it turned out I sure as hell didn't have to. There was myself and one young guy that was on a Harley that didn't put a foot down or run over any cones, and all six of us moved on to the road part. But give you a rundown, it is the same order as in the book, walk your bike in a figure 8, then do the serpentine there and back, (now don't go too slow, a little quicker and it will be much easier without any deductions) then slow down the centre of the pylons then fast back and brake, now the tester I had preferred us not to skid as I have read some want you to skid, but they will give you the opportunity to ask any and all questions before you start and there is nothing wrong with asking that. Once you do these, it takes all of 3 to 5 minutes, and you pass he will tell you to go park and wait for everyone else too finish. We all passed this part even though some of the guys were just brutal!
Next we drove to a small parking lot at the main intersection of the town we were in and one at a time he gave us instructions as to where he wanted us to go and as the other posted said, make a left in an intersection (make sure you are in the proper tire track) and then go through some back streets and back to the main intersection from the opposite direction and again make a left in the intersection, again make sure you are in the proper tire track and remember as the one guy that failed, pedestrians have the right of way, even if they just stepped out.
But it was very easy, and as I said, only one out of 6 of us failed.
Good luck and don't stress, it was very easy.
