Good Luck with M4ML its a great course! Covers a lot, I was impressed, wish there was some videos or more visuals but it doesn't hurt to use youtube. I took maybe 7 pages of notes on my github and each over 4000-8000 lines (I used the notes to do the step by step exercises it was easier for me to type notes and do the exercises on computer than pen and paper this is what I used to do).

I take the notes because I will probably forget, but I think its key to always be learning and keep practicing even when your done the course.

Once I get hired again I will def take Discrete Mathematics. In the mean time I've just read books on ML and LLMs, free online courses, youtube videos etc.
