Easier College Classics
To ensure your success at the College Classics challenges, start a game, then go to the AI Settings in the Settings menu (from the pause screen). Set all of the CPU's offensive and defensive skills as low as they can go. You can also change any penalties you'd like. We suggest turning off defensive pass intereference if the Classic you're trying to beat involve any sort of pass defense.

Touchdown celebrations
When you score a TD, the word "Touchdown" appears. When it first appears, press the following button combinations. Note: This could also get you an 15 yard Unsportsmanlike Conduct penalty.
[L] + [X]: Player spikes the ball, points to the crowd, then beats his chest.
[L] + [Y]: Player bows to the crowd.
[L] + [B]: Player spikes the ball, then shrugs his shoulder.
[L] + [A]: Player does Heisman Trophy pose.
[R] + [X]: Player will dunk on the Goal Post.
[R] + [Y]: Player will punch the ball towards the crowd.
[R] + [B]: Player will kick the ball into the crowd.
[R] + [A]: Player will throw the ball to the crowd.

Extra campus challenge points
Play several games at the Heisman level, however alter the AI settings in the settings menu before playing. Set the CPU levels at their lowest, and the Human levels at their highest. This will force the CPU to make a lot more mistakes and you to allocate challenge points, which can be used to purchase pennants and unlock other secrets within the game. The play level is still very difficult, but with your added AI, you should be able to be successful.

CPU control
Snap the ball. Do not press anything else. The CPU will sense that you are not playing and will play for you. They will almost get a touchdown or a very good pass or run. If you press anything after the snap, you will have to play. This works best on pass plays, and only works on offense.
