Baka to Test to Shoukanjuu, R-15 Recommendations
Similar humor,both are random and funny :D, both have a touch of shonen ai between the main characters, similar art.
Both are comedies set in a school scenario. R-15 is more ecchi kind of funny while Baka and Test is more the stupid kind of funny. Both are great, and you should like both of them if you liked one of them.
R-15, a guy with an unusual talent trying to survive this genius academy he goes too with his friends.
Baka to Test a guy being put inside the F class, and is seen as stupid and is trying to prove to the school that tests aren't everything.
these animes both have really great personalities for all characters except for the fact that I hat short haired guys in baka to test to be loved by a beautiful long black haired girl but overall these two anime are really good especially if you want to have a laugh and at the same time have school life and romance added on to that
