Mute City: Twist Road
This is a track where you can confidently use your boost the whole way around. Use the slow first lap to put yourself in good postion for the rest of the race. Maximum points shouldn't be a problem here. The track is wide and easy to navigate, so it worth taking out a few cars. If you are tackling this on master mode this will be handy if you can take out five for a vital extra life. Other than that, the game doesn't get easier than this.
Casino Palace: Split Oval
With so many boosts on such a short track, it could be hard to take any cars out here, so you should probably concentrate on winning it instead. At the fork, take the left hand lane to get energy on the second and third laps. But for the start lap take the right, as there are four booster pads up there. Again, boosting all the way round isn't a problem so you should make it two wins from two.
Sand Ocean: Surface Slide
This is the first track you encounter where a conscious boosting strategy comes in. you should use two boost in the tunnel where the energy lanes are. Then you have to watch out for the chicane as you exit the tunnel, a sharp right, then left. This will lead you on to a straight. Boost twice on this straight. That is then followed by a long left hander, stay as close as possible to the edge round here. Then on the end straight, boost twice. This should get you in the top three if not a win.
Lightning: Loop Cross
This is complicated because you are bound to take hits from the other racers. There are two strategies for this one. Either try and take out the nearest racers to you on the total rankings board, or go for the win, which can be tricky. Nothing is guaranteed, even at the end some erratic racers just come from nowhere and smash you into the side (i.e. Black Bull!!!) and you correspondingly lose five places. So it up to you which to choose. But despite this, it's probably more safe to try and take out your main rival, and then go for the win.
Aeropolis: Multiplex
If you boost wisely on this course, you rivals will never beat you. There are two tricky turns though, the square hairpin at the start, and the chicane after the jump half way through. Boost on all the long straights as much as possible. To avoid crashing on the hairpin at the start, spin attack around it instead and boost to make up the lost speed. If your lucky or just deadly accurate you'll take a racer out here. The best killing zone on the track is the dirt ridden straight. Also the jump at the start is great for a bit of traffic jumping, and can often shoot you into the lead. With all this in mind, you shouldn't finish any lower than third.
