Which starts a group of kids that are in a gang, that are into horror movies. They find out that monsters are real and that dracula is his teacher. Does anyone have any ideas to the name of the movie?

I'm going to say its Monster Squad. http://www.imdb.com/title/tt0093560/
Though that may not be correct, there is however a scene where the mother tells her son who leads the "gang" that someone from school called named Alucard. Which of course is Dracula spelled backwards and it shows him writing that out and freaking out about it.
