Took another step towards PhD-dom yesterday when I registered for 3 courses and paid up tuition for them (ouch). Started with two courses for 4 credits, and then ended up adding a third 2 credit course when I learned that it was a required course only offered in the fall. I was originally only going to start with one class this fall to ease my way back into student-hood, but I figured since it's only offered once a year, I might as well get it over with and add the third course.
First courses on the docket: BIOE 800 (Seminars in Bioengineering), BIOE 801 (Biomaterials) and CGS 710 (Responsible Conduct of Research). I've heard CGS 710 (offered by MUSC) doesn't require a lot of work, so BIOE 801 is probably the one that I'll end up spending the most time working on.
Now to find the textbooks for the classes.
