that blasted schedule

so I think I've got it figured out what all classes I need to graduate in 4 years. If I take 16 this upcoming fall, then 12, then 13, then 12, I'm home free. Of course, that's for just the math and ENGR degrees. I want to take other stuff, intro to quantum physics, maybe 1st semester latin or Japanese, an econ class- well, now they've got too many restrictions now :(. <-- not a pimple. I was thinking of signing up for Psych 101. I know I've heard from people named Alice that it's waste of time, that it's more efficient to just read material o your own. True, but that would bring me to 19 units, so I'd be kinda swamped as it is. But the issue is that I AM signed up for 19 units now. I signed up for 2 engineering classes that I could use as electives, and I was gonna drop the one I liked less. But one is in serious distress of being dropped for lack of enrollment (9 of 35 seats- not too good) and the other one I'm not 100% sure if it actually counts as an elective because it's hosted by another engineering department.

To be specific:

AME 460- theh low enrollment one. Mechanical vibrations. Free and forced vibrations of simple mechanical systems; effects of damping; introduction to multi degree of freedom systems.

SIE 431- the one I'm not totally sure counts. Simulation Modeling and Analysis. Discrete event simulation, model development, statistical design and analysis of simulation experiments, variance reduction, random variate generation, Monte Carlo simulation.

So I don't know. I don't have a lot of wiggle room, but I might have too much. Not sure.
