This channel[1] (by the sounds of it) isn't exactly what your looking for, but I feel like it's appropriate for the topic and might act as a supplement to whatever course(s) you end up taking, depending on where you are having difficulties.

He has an amazing ability to break math down into intuitive visuals which highlight the underlying nature of math, rather than being hyper focussed on a specific problem. For myself, the videos have allowed me to pick up other/adjacent math concepts significantly easier because I've developed a signficantly better understanding of what's happening "under the hood", so to speak.

Might be worth a quick look at least!
