Extremely informative, however I just wish there was more hands-on learning rather than just watching videos. Nonetheless, it is still a great course worth taking.

The course is technical, a challenging aspect to an non-IT graduate but very easy to go through thanks to the explanations of the lecturers involved in this course.
