General Tips
When going for faster times, try to keep as close to the ground as possible as you can skate faster on the ground than you fly through the air. Make small hops where possible!
For Jet Tech there are a few rails in the game that give you much more points than normal. Find one of these and just use Y tricks backwards and forwards down the rail until the time is up. Put in a jump and some tricks just before the end.
