That's just off the top of my head. I know there's a couple I'm missing. Carranza gave the best advice though, just keep practicing, you'll get it. OCRC has a great facility for beginners though because you can practice on the small track without the fear of getting in the way, then once you feel like you've improved your skills enough, you can take it out on to the main track.
