There are several posts around the forums here based on tips for achieving 3-star ranks in each of the cups. Look around, and I am sure you will find some. Oh and no one cares if you completed all of it 3-stars, lol quit saying it. Your right, it was the easiest, so why are you bragging about it? Do you brag about brushing your teeth every day? How about putting in a microwave meal each night? Hmm, or writing your name on those reports, you brag about that?
- Don't hit walls too much(try not to at all).
- Stay in first place 90% of the time. If you've fallen back, and you go almost a lap being in anything but first, you mind as well restart.
- Stay out of grass or other areas.
- Don't hit items or obstacles - Don't fall off the track(you can get away with it once I think).
