Each coding exercise includes code the student needs to complete its missing parts, and submit. Taking this course, if you feel that you would like to have more exercises of a specific level about a specific topic please don't hesitate and let us know. We will take your needs into account when working on the next version.
If you encounter an exercise you fail to complete and have difficulties understanding its solution please let us know and we will prepare a video that explains that specific exercise and its solution. If a video already exists and you still need more explanations please don't hesitate and let us know so we could improve the video that already exists or prepare another one.
