Studying English is like learning to play a musical instrument. Whether you want to learn how to speak English, learn how to improve reading English, the more you practice - especially spoken language, the better you get at all the other skills. It's a simple principle. It's still a lot of work, but if you follow that, you will be successful.
Most ESL classes spend too much time learning English grammar. It's true that grammar is important, but learning language is like learning to swim. You can't do it by reading a book -- you have to practice!
Very good school. Teachers and staff are really friendly, and I made a lot of international friends there.
