The Callan method is a fast and fun way to learn English focusing on fluency, understanding and pronunciation.
You can learn to speak English in a quarter of the time. It's possible for a student to go from complete beginner to an advanced level in a year of studying, which is much faster than with other methods.

The teacher asks questions designed to practice a particular piece of vocabulary or a grammatical concept, which the students answer with the teacher’s help. 70% of a Callan lesson is speaking (with a little reading and writing), so everybody gets lots of speaking practice.

Callan teachers speak at a natural speed; the same speed that you might hear when you’re at work, out shopping, having a meal in a restaurant, a beer in a pub or watching a film. The speed of the Callan Method gives you no time to translate into your language, so it allows you to think and speak automatically in English, using correct English sentence construction.
