Dear Friend
we have lots of topics about Toefl and prearing for that, But I just recommend you to improve your english knowledge before attending Toefl classes,because Toefl classes are just about Toefl and nothing else.
About classes, we are not allowed to introduce any class here

, and also everyone has different ideas about describing the best teacher and best institutes.
In my opinion all English classes like kish, kanoon, safir and etc are good. In fact learning English depends on your try and effort in learning it.So teachers and institutes are just some tools to put you in the right way. Try to expand your knowledge through watching movies, listening to radio and reading lots of books.
Wish you luck
