Joshikousei doesn't do anything crazy, but everything is well made. Dialogue, characters, art and sound are all pretty good. I was actually pretty surprised at the soundtrack--nothing crazy amazing, but certainly for a comedy anime, top quality. OP and ED are also enjoyable, and I found Teishoku-P to be pretty good, it was probably the least expected place I thought Volcaloid would be played, honestly.
I'd say that the story arcs and dialogue are well constructed, and carry the anime to great heights. None of them are particularly bad, and the interactions are quite well made and pique your interest, even though the situations are typical slice of life.
That being said, the reason why this is an 8, and not, lets say, a 9 out of 10 is because of the characters. The main cast is amazing, but some of the side cast and characters are really gimmicky and one dimensional. Robo, Baka, Ninomae, Wota, Yamai, and Waseda are fun characters to watch in action. While you wouldn't call them extremely unique, they fit in their niches and aren't characters you can predict to what they would say, and they can fit in a lot of different dialogues, environments, and interactions with other characters. Then you have Saku, Lily, and Majo, on the other hand, are pretty much one-liner characters. They're pretty predictable, it even shows with how they interact with in terms of the rest of the cast. They are restricted to talking to a few select people, and how they even became on talking terms is also not exactly established either. It's a hit or miss when those characters are part of the focal point in the "skits," stories, whatever you want to call them. On the other hand, what I would consider the "good" cast usually won't disappoint.
I think it is a little nitpicky, because I still enjoy more than half the cast, but I just wish that there were less archetypal characters. Yamai is enjoyable because of the way the author presents herself in situations, but she too, is quite a trope in these types of shows. I wished that the cast was smaller, and focused on the main cast. I mean, Asobi Asobase had only 3 main cast and few side characters, yet it managed to pull it off brilliantly. While I wouldn't just want 3 characters in Joshikousei, I would want a more concentrated focus.
Overall, a great show for comedy and laughs. As a person whose favorite genre is comedy, I was too easily taken in by this show.
