Heres a good tip to newbies.
If you arent sure, ask. People are always wlling to help, and dont worry, we have all done it.
Also, driving wise( I still do this if I goto a new track) Stick to the middle of the track. Then, after a few laps, you will naturally begin to get closer to a corner, or take one wider to get the next one tighter e.t.c. Thats how you build up speed. Don't try run before you can walk
