learn how to use photoshop

I started learning to use Photoshop several years ago. I was able to teach myself how to use nearly every feature it offers, and I became excellent at editing photos and creating graphics. When I started to study graphic design in college (which I did for only one semester), I took a Photoshop / Illustrator class, but I already knew everything they were teaching about Photoshop. My professor was kind of pissed off that I knew the stuff, and it made me sad because he actually didn’t like that I finished my projects so quickly and ended up with free time. It was stupid. So, the lesson here is, learn to use Photoshop, but if you study graphic design, don’t let your professors know that you already know how to use it. :P
