I agree with ‘vanguardian’ – I am a graduate of Visual Communication from ASU. And I would also ask you what you want to achieve. Is it just Photoshop and Illustrator, etc. or do you want to learn about typography, illustration, layout, design, color theroy, and the like? If you just want the Photoshop I would honestly just purchase a good book (The ‘bible’ series of books worked great for me) and practice at your own pace and for a much cheaper price. If you want to actually learn desing and layout and use it to “profit”, I would go with the courses that your school offers, assuming that they teach design theory and are capable of critiquing your work on a professional basis, and not simply how to work a certain program.
My 2 cents.
