Anyone know any Highschool / comedy like anime?

Ouran High School Club
Fruits Basket
Kaichou wa Maid-sama
K-On!
Uta no Prince-sama
Special A :DDDD

Vampire Knight must see :)

Baka and Test:Summon the Beats is a HILARIOUS anime that involves a lovable idiot named Akihisa Yoshii and his vrienden in Fumizuki Academy; a school that divides their students in classes (A to F) door their scores on a special test that basically judges how smart they are. At Fumizuki Academy all the students can summon "avatars" chibi versions of themselves that gain power from how high their student's test scores.
I won't explain it all. Just watch it, it is great.

Clannad, Lucky Star, The Melancholy of Haruhi Suzumiya, Full Metal Panic, Heaven's Lost Property, The Familiar of Zero, Shuffle, and K-On. Those are the only ones I've seen (besides rosario vampire) that match both your criteria.

A Certain Magical Index and Is this a Zombie? both are action comedies where the main character is a high school student, but school isn't considered one of the genres.

I highly recommend Sket Dance.

How about Danshi Koukousei no Nichijou/Daily Life of High School Boys. It's a pretty interesting anime. And in the main cast, 2 of the seiyuus are link as Hidenori Tabata and link as Yoshitake Tanaka

I recommend Negima!?, an awesome anime that takes place at a high school! It's about a wizard who goes to be a teacher at an all girls school, and it's pretty funny. ^_^

maid sama

Seitokai Yakuindomo ;D

Ouran High school Host Club. its one of my favorite.
and there's an English dubbed one on Netflix

Give Nichijou, Toradora!, of Daily Lives of Highschool Boys a try! Those are pretty great.
This is Nichijou's opening.

I recommend u to watch Prince of Tennis,it's full of sports,comedy and,school and slice of life...
