You begin the game at SciLab, and once you gain control of Lan, talk to everybody. Once you're done, a cutscene will trigger, and you will jack in. Time for the god-awful tutorial. Follow it through then jack out. Another cutscene will happen, and you will regain control back at school. Talk to Mayl, Yai, and Dex to arrange to go to the park. Get out of school and walk down to get there. Another cutscene, TV guy walks up, tells you to go to the preliminaries of the N1 Grand Prix in ACDC square. Do that. Jack into your computer and get on the net, then complete the missions. The first answer is "x," second is "o," third is "x."
