How do you get 2500 points in the pain and panic paradox cup in kingdom hearts 2?

The trick is the round with all of the rabid thrusters. When the round starts, use Magnega and Thundaga as much as possible. With this, I got 2000 points just in this round. If you can't seem to get this, just remember to kill all the enemies yourself. The ones that Donald and Goofy get, I think, do not contribute to your point factor. I'm not sure of this, but definitely use Magnega and Thundaga.

Good luck!
