Ok guys, I've got some great news. The guys over at maxconsole constantly amaze me! RoBoZeO has just released 2.4 of his awesome GTA:SA trainer. There is now a schools option. This will give you 100% on all schools.. Yes it works on the extremly difficult, terrible, dreaded "learning to fly" mission
All you need to do is take off and fly that baby straight into the ground and you will pass. He's also added an option for unsensored girlfriends. Icing on the cake! Anyone having trouble with any of the school missions should go grab this gem of a trainer and save yourselves alot of time and frustration. Maxconsole Forums
Oh yeah.. a little tip for those having hell with the Zero missions. Theyre all optional. I've only done 3 of em and I've unlocked all of the cities. Have fun!
