I've noticed that I have a habit of copying the annotations that my professors do during lectures. Ex: if they circle a diagram and underline a word, I usually do the same on my iPad. I think this may be distracting me since I usually listen to recordings on faster speed (1.5x-2x). Is it useless to try and mimic what the professor underlines/circles? I've been thinking of just annotating whenever the professor says a certain topic is "important" or "high yield"
