I made it a point to take detailed notes for all of my lectures in college, and I did pretty well in my courses as a result! So here's some advice. Consider taking notes by hand instead of using a computer. I found one study from some time ago that suggested handwritten notes are better: https://journals.sagepub.com/doi/abs/10.1177/0956797614524581 https://journals.sagepub.com/doi/abs/10.1177/095679761452458... I personally find taking notes by hand better for me. Since I can't find any studies replicating the result of the one I cited, I suggest trying it out and see if it helps! When I was taking notes for class lectures, I would split sections of notes by date, titling subsections in a given day as appropriate. This sort of chunking will help you remember the notes better, rather than writing in one continuous stream. If you're taking online courses to learn some programming languages, I think this method will work! If not, I would suggest keeping a notebook per programming language and just organize your notes by day. When taking notes, you do NOT want to copy what's on screen or what's being talked about verbatim. You want to capture just the highlights, so that they'll jog your memory later. I generally write tons of bullet points instead of complete sentences, and I end up with more of an outline at the end than paragraphs of information. If you need the finer details, it's better to go back and review the source material itself. Once you have your notes, you can review them by going day-by-day. For your case, if you need to refer to previous sections quickly, consider bookmarking them with sticky notes. (Not sure how you would do this digitally.) You might be surprised to find that the act of writing down the notes was enough to keep them in your head, and you may not actually need to review your notes often. Hope this helps!
