THE BEST WAY TO WIN is repetitiveness; race on a track enough times till you remember where the sharpest corners are & learn how to best take each one. Also don't worry about trying to over take all 24 cars in lap 1, try to get down to about 7th place when lap 2 begins concentrate on perfecting the lap not the cars & before you know it you'll of beaten them all. Also you can try to complete most the achievements by repeating level 1 a few times aiming for a particular achievement to pass each time
