It was the third course I've completed (secong in foreign language-English). I speak English at intermediate level and I can say this course is not difficult (thanks for russian subtitles sometimes). As for me, to understand the course is not difficult too.
It is kind of short course, and I think it is very good. There is no long videos, so you can practise "pomodoro"(one of the tricks which you will learng in this course).
The course is very informative and helpful.
In the corse I found many mistakes I have when I am learning. So, I can avoid them in the future.
So, I DO reccomend this course for everyone (for one who just starts his first course or who is advanced learners).
Thank you Barbara, Terrence and your team for the very great course. I hope I will learng something new from you in the future:)
