Worked on calculus. Took a few hours to read, work examples, and work problems, but we're on a rather tedious topic right now, so being able to grasp the concept and work that as many problems as I did (about 25) in only a few hours is reasonable.
I also, for the first time since the start of the semester, had to work on a programming lab over the weekend. Somehow I didn't finish it during the actual lab session yesterday. Well, I would have complete it, but the TA gave a piece of advice before I turned it in, and that saved me from submitting a program that failed to account for a few odd scenarios you normally wouldn't think of. So I would have completed it, but it would have been poorly completed.
As for the rest of the weekend, I don't have many plans. For the most part, I'll still be doing school. Tomorrow will be dominated by music and calculus. I may read the next chapter for programming and glance at physics, but honestly, those classes are beyond easy, so I could easily fit them in over the week and save tomorrow for more time-consuming classes.
