There are two power boosts in Mario Kart. 1 is when you first start off, just before the "blue-ish" light goes, hold the A button for a boost at the start. remembering to steer away from the other people. the other is when you are cornering. hold the R button, and the corner must be over 90 degrees sharp (I think!) and once you come out, should get a boost. REMEMBER, you must hold R the whole time around the corner
You must have a mushroom. When you are 10 feet back use your mushroom and there will be a jump. It will put you 3 or 4 Rankings
(this cheat only works in time trials)
On Koopa Beach 1, get a boost start and turn a hard right. Use a boost across the deep water tapping R. Do this every lap (it even works without a boost
You must hit all the dash plates to go off the jump. You may fall off track. This will put you a couple of places
You must hit both dash plates or have a mushroom. At the first jump, use your mushroom or the dash plates. Turn on the second right. You will be right out in first
Go to Sky Garden and drive to (a little bit before) the second vine bridge. Look to the left an you should see a cloud. Hop on to it and hop on to the other road. This should put you one place ahead.
On Snow Land after the third bend go to the left side of the track (on the hard shoulder) and you will see a path cutting a huge bend. You will also pick up about 20 coins and go over a series of boosters to get you well ahead in the course.
There is an almost 180 degree turn before the first bridge well there is a jump near it. I'll giveyou a "drawing" to look at.

AND you can use a boost before the jump to skip over tons of track!!!!
You need a star or a boost for this cheat to work. When you have a star or a boost wait until u get to where the lake is there is a munching plant there so be careful. When u see the pool take a very sharp left use your star or your boost there will a munching plant the boost will be to quick for it and the star will just go over it after that there will be a vine bridge there jump over it. This cheat may put u 2 or 3 places up the grid. This is especially good for time trial.
