BTW, I’ve just read some of your notebook entries, and I want to congratulate you, because your English usage is already more accurate than the English on the website. It’s quite clear that you are a lot more advanced than the low-level learners the “Callan Method” is designed to teach.

First of all, this so-called “Callan Method” doesn’t seem to be anythings special — rather, it’s an attempt to market a random “method” that can be quickly learned by anyone, in order to create instant “language teachers.” Second of all, I’ve just looked at the website you mention, and I can say that their page describing the method was obviously not written by a native English speaker. I can’t imagine why you’d want to hire a Polish person to teach you English. Any good teacher knows lots of “methods,” and will choose the best ones dynamically, based on the needs of the student in front of him. I’d strongly suggest you take advantage of italki, where you can see videos and get detailed information about real teachers who use italki as a platform, instead of dealing with completely unknown people hiding behind their own slick website. (Do you realize that anyone could start a website like that today?) I am honestly curious why you wouldn’t just find a teacher on italki, where you can see detailed information about hundreds of teachers (just for English) in all price ranges.
