Which are the best schools for EJU classes?

Hello,
My name is Leticia, I came to Japan to try study in a University here, Now I'm just working, but I plan start Japanese and preparatory classes on October.

I searched many schools, But still I on't know which one could be better for me, Of course I'd like to try the University of Tokyo, I know that is not easy, definitely. I'd need a high score at EJU (Math II, chemistry, biology, Japanese).

Does anyone know schools where I can have good preparatory classes for EJU?

I saw about one school affiliated to a Japanese university, it got my attention because the students can share places with Japanese students (cafeteria, library, the entire campus, I guess), But I don't know about the application deadline. I sent an e-mail, I'm waiting for the reply.


Please, I really need this, do you have any recommendation about schools?
