I went to school for audio/video production and have a job as a video editor/ specialist. Before getting picked up full-time I was planning on going back to school for another 2 year degree, this time in graphic design, seeing how now-a-days motion graphics and video editing go hand in hand.

I work at least 40hrs a week and have recently started paying back student loans, so I'm looking for a cheap and effective way to get some design chops while learning at my own pace.

I'm quite familiar with Illustrator, Photoshop, and After Effects, so I already know how to use the tools and would like to mainly focus on learning the aesthetics and principles of graphic design.

Rather than just reading and trying to retain information, I'd like something with a lesson plan and exercises to work along with. I'm not trying to get a degree or certification of any type, this is strictly for my own personal growth. Any suggestions would be greatly appreciated!
