First of all, you should determine the learning method. If you study full-time, it will take at least 4 months to complete 500 class hours. But if you study part-time, it will definitely take more than 2 years. The test is TCF or TEF. My friend used to study in the Great Wall. She studied for five months and got 340 points in the final exam of TCF. But five months is a bit bitter. But just stick to it! ! I can't remember the cost clearly, probably 13000. They seem to have a minimum score of 280. Ask yourself!
