I Need a Computer Tree

My school has this crazy idea that they can assign homework that requires a computer to me and my two brothers on the same night, while my parents need to use a computer for day to day stuff, too. There are three computers in my whole house, one of which we got just to meet these computer-required homework assignments, and one of which is old and loaded up with spyware and viruses and junk filling up the RAM, and only one of which has a printer attatched, and only one of which has the proper software installed to complete my homework assignment (which is not the one with the printer). Long story short, I couldn't get started until 8:30 tonight. I'm still not finished, so this is a short entry.
