HP(of computer and printer fame) offers some great free classes and learning tools at:
HP offers a wide variety of computer and IT classes, as well as basic business and home office education. The classes are free, totally online and lead by working professionals. You can ask questions of the instructors and chat with your 'classmates' on the discussion boards.
After succesful completion of your class, you can print out a certificate for that class.
You won't get college credit (unless your college accepts these as life long learning credit. You could ask!) but you will get excellent information and training for free.
I've taken several of these courses and I learned some skills and information at HP that weren't included in the advanced IT courses I took at my community college!
