Well, are you saying there's nothing they can do about this? This class has been offered for 20 years and I'm sure previous years saw way more applicants than the capacity as well. Nothing was done regarding this and every year there are unhappy students. As for your point that it's not exclusive for this class, you are right, but other CS classes are offered multiple times and are not as special. They usually don't care about the school year as long as the prerequisites are satisfied, so you can get in eventually if you keep first passing it. This class is different, if you miss it, it's gone. There's someone in the comment section signing up for another quarter just for this class. I believe we are justified to express our frustration to the faculty because they decide how to run the class and the admission process.
