You might consider responding to your classmate with the following points to facilitate a constructive discussion:
Hi [Classmate's Name],
I appreciate your insights on the student's notes! I agree that the repetition of "Four" was notable and that once an observation is made, it shouldn’t necessarily need to be repeated multiple times. It can be more effective to focus on a variety of points instead of circling back to the same one.
I also see your point about the different quality of annotations. While some corrections are helpful, having clearer, more in-depth notes can often enhance understanding and retention of the material. It’s interesting to hear that you apply this method to help friends and family with resumes—it's a great way to reinforce the skills we learned in school.
Have you found that certain strategies work better for different types of texts or subjects? I’d love to hear more about how you balance detailed notes with overarching themes when studying!
Best,
[Your Name]
