They are not actually!
We intentionally keep our prices low to make classes more affordable because we know that language learning takes a long time (if anyone tells you otherwise they are lying to you). And no matter how great is the tutor, the app or the method you are using to learn a foreign language you will not feel like you've learned much after just 10 classes or so. As a matter of fact the opposite usually is true: the more you learn the more you feel like you don't know anything. Sadly it's just the nature of learning a foreign language. If we charge an arm and a leg, let's say $20 an hour, after taking 10 hours ($200 in total) you will most likely quit.
