I typed my notes in an app like OneNote (this is a while back, I forget what it was called). During class, I'd type an outline of the concepts and examples given in class and then organize them away later, with each tab being a different concept. If I didn't understand something after the fact, it was still in my outline, and that was a sign that I'd have to ask the professor about this concept later. A lot of people will tell you to write everything down and do something with it later. If you didn't understand the concept in the first place, that's not going to help! This is why writing notes didn't work for me. I write slow, but I type fast. Being present, physically and mentally, in class was important for me! I couldn't do this if I was falling behind writing things down. Also, ask questions if you don't get a concept. Writing what the professor says verbatim is not a note. Writing the underlying concept down is.
