In the Moscow level, find the place where there are a lot of tanks and a building that reads "AEHNH". Stand in front of the building to the left. Line your self with the brown ledge. Climb up it. Stand on the brown ledge that you are about to grind on. If you are in the correct location, to your left should be a tree and straight ahead should be a big red building palace-looking thing. Grind that ledge and jump toward the previous viewed window. You should go down a ramp. Where the ramp is located, is a ramp that goes up on the right, revealing the "Tony Hawk 2" icon as you went down the ramp to unlock the Hangar level from Tony Hawk's Pro Skater 2.
In the New Jersey level, cross the bridge, then get on top of the large building immediately afterwards. Shimmy across the tall gate and pull yourself onto a ledge. There will be a "Tony Hawk 2" icon on the ledge alongside a tall building that will unlock the School 2 level from Tony Hawk's Pro Skater 2.
While off your skateboard (walking), when you jump the first time, you can also jump a second time while still in the air (if you keep tapping Jump). This is very helpful for out of reach places. Note: You can only jump twice.
Create your own deck or get any pre-made one. Grind a lot with it by doing tailslides, noseslides, boardslides, and lipslides. After grinding for so long, your board will wear on the bottom and the picture will be all scratched up.
