A while ago I reviewed the first season of this, and I just found this show to be hilarious. At the time I was thinking 'just how can you top the first season'; well now we'll find out with Baka and Test Season 2.
If you read my review of season 1 you'd know that there is some sort of story, but with this season it's more like a series of jokes that have they're own stories that span one, or two episodes. Some of these tiny plots last half an episode. There is one story that does span at least three episodes that's all about Akihisa finding out who's blackmailing him, but that does turn into a complete and utter 'laugh you're ass off' story that is so stupid that you just have to laugh.
In terms of plot there really isn't one apart from separate stories, but this isn't a bad thing by no means. This just gives the series a chance to delve deeper into character development, along with trying to be funnier than the first season.
ANIMATION & SOUND
While the animation is slightly better than the previous season the art style is still the same, and the voices are just as good as ever. I even like how the women that plays Minami puts on a very accurate German accent in one episode, which is saying something as when it comes to anime accents never sound that accurate.
If you liked the previous season of Baka and Test then you should enjoy this season, as this is, in my opinion, the funniest so far. There are some moments in this season that are the funniest in the series, and just stand out. Like the first season you can watch it again and again, and always notice new things when you re-watch it.
For these reasons I recommend to buy this if you are a Baka and Test fan. Though this series can be stupid at times its just a bit of fun.
