評分和審閱
Very good material! And made to be very interesting as well! Thoroughly enjoyed my learning experience.
This course was really good but there were lot of contents in a single video.
With subtitles (as the audio is only in French) it is difficult to pay attention to the texts and diagrams on screen as one is busy reading the subtitles.

thank you so much
