There was this show on some mexican channel I think it was Telemundo. It took place in a high school, and all the characters wore school uniforms in it. I can't remember the name. Anybody can help me out.
The girls in it wore black skirts and had white shirts with ties. I just can't remember the name of the show.

Sounds like "Clase 406", but it has been awhile so I cannot be sure.

Clase 406

Let me see, not too much information, but lots of description of school girls in uniforms. Somehow I knew DS would have the answer.
