I'm coming to the end of my first year (6 year part time) Comp Sci course and have seen that we have options for AI and Machine Learning modules in future years. Where should I go to find something like a list of what I should be brushing up on, or learning completely from scratch, in order to not fall flat on my face during those type of modules. I understand there are very set starting points in math subjects because concepts build on one another but I don't know what I should be starting with and where to go afterwards.
