probably the worst unit I have ever taken, if you don't like coding this isn't for you

Best unit ever. Drew is amazing and the concepts are constantly reinforced and well taught. There are practice quizzes every week and practicals are fun and interactive (even when done via Zoom). Definitely not a subject to be worried about although I would highly recommend you actually attend the lectures and practicals live rather than later on. There are lots of opportunities for asking questions and discussing content.
