Hint: Do more than a 900:
Go to the Downhill Jam level. Go to the part after the first Mountain Dew sign but
before the second, where there is the top of a hill. Move into the right wall on the end
closest to the water and press A to do an Ollie or Up + A to do a Nollie, and hold L or
R. You will not see yourself spin but when you land it result in either a 1080, More
Nollie or Mega Ollie.

Hint: Getting air for Tony Hawk's 900: 
If you are having trouble getting enough air to pull off the 900, do a 540 Board Varial
by pressing Left(2), X. This will provide more than enough air for you to earn 8,000
points on the next trick.

Hint: Upside-down wall ride (demo version): 
Find a corner of the warehouse where you can go from wall to wall. Do a wall ride on
the first one and jump off to get higher in the air. Then press L and do a wall ride on
the other wall. You should now be doing an upside-down wall ride 

Hint: Go through the fence (demo version): 
Go down the ramp that the game placed you, which should be the one with the fence.
Go down that ramp and jump into the fence while doing a Kickflip To Indy. Keep
spinning into the cage. After a moment, you should go through the fence and land on
the other side.
