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.
This is the best course for beginners.
First of all, I found the course really interesting and fun. It has helped me develop new insights in to the world of satellites and how our day to day activities are supported by them. Now i would like to mention some areas of future improvement.
First, more numericals should be included where ever they are required.
Second, lecture slides should be made available for reference. Although I understand students are encouraged to make notes, but for quick future reference, lecture slides are always helpful.
Third, the Last week by Julien should have been more detailed and systematic. I got confused while attempting the last week quiz. Even after revisiting the videos my confusion has not cleared.
Thats more or less it. I would like to thank the entire team for creating this wonderful course. I look forward to many more offerings in the future.
This course was really good but there were lot of contents in a single video.
