I use OneNote for my digital note taking. I create a section for each class, and start a new page for every new topic introduced in class. This usually goes by chapter, but sometimes I do it by class period.
There are many options for types of notes. Sometimes I simply type out my notes, using lots of bullet points to keep things organized. Most of the time, I take notes with my stylus on my two-in-one laptop directly onto a blank page. This method is my favorite, as I retain things better with traditional pen and paper notes, but there’s the added bonus of the technology that organizes everything into folders. Another strategy is to download a PDF of the lecture notes and write directly over the top of them. This is useful for powerpoint presentations because you can write down what the professor says and still get all the information on the slide.
Overall, digital note taking saves paper and is much more sleek and organized.
