I graduated with my B.S. in biology last year. My plan was to go into grad school for bioinformatics, but it turns out I need a lot more computer classes to do that.
I started working on a computer science major at a state school last fall. My first semester went very poorly. I put all my time into calc2, but half of the calc2 class failed because the exams were too tough to finish on time.
So all the classes I'm taking this semester are courses I started taking last semester. But I'm sure things will go better this time.
