DON'T CHEAT PEOPLE, IT TAKES AWAY THE POINT OF EVEN DOING IT anyway i've been at it for almost a year, i'm stuck at level 78
it has 138 lvls counting the positive, negative and greeks and only 90 are certified to have finished the game... :blink:
LOL. i have cheated so much and i am still not THAT far (don't think i even passed level 25). it was fun by enjoyed seeing the answers more than trying to figure it out... some are pretty sweet!
