great application
The app is a very good . There is a clear structure for presenting teaching material. All videos are close to life situations. Many subtle points are discussed that are not written about in books. And also I want to note the gradation of the material by levels. And I want to catch your attantion that there is a wonderful support service that will be in touch with you all 24 hours and will help you solve your questions. I want to express 1000 thanks to the creators of this application and their team! Best regards, Elena
