That’s very true. Everyone does learn differently.
I was the type of student that always copied my notes over. My notes were a mess and rewriting them was really a great way to study for me. If I had the tape recorder, I went over my notes and added what I missed. That was a way that I learned.
I had an embryology professor that gave detailed essay questions and would take a huge amount of points off if you missed one tiny detail. She didn’t really teach from the book and half the time she forgot what she mentioned. More than once I went to her with my tape if she deducted points because she forgot to mention something and took points off.
I was able to pay attention more to the lecture when I knew I had the tape as a backup. They also helped me for exams.
