Level 30554 Lol
I wonder if you people used the mouse instead of the keyboard :P
Simple: Press the Tab button sometimes to select the button (Sleep, Study) that you want and then hold the Enter button.
Just get some intelligence and then work. When you get enough money, use the above trick and select Work Out. If you get bored of having your finger on the Enter button, just put something on it. After some minutes your level and strength will get over 10000!
