Reminded me of the Feynman’s technique. I relate completely. One of my biggest challenges in returning to university after several years of work was exactly having lost the grasp of prerequisite knowledge. Unfortunately, from experience, more often than not lecturers just play the “you should know this from previous courses/high school” card and you are pretty much left alone in your struggles. Gets even worse if an exam problem relies on some borderline trick that wasn’t practiced throughout the course. You could probably tell I haven’t let go of some grudges.
