In high school, I hardly took any notes and I managed to do ok. I'll try to do the same thing in college and see how it works. You may have even said these things. In college, you are expected to learn the material, to be challenged by the difficulty of the material and to absorb it at a faster pace than in high school. This may be a tall order depending upon your past study habits in listening and notetaking.
College is a time of growth.
It is a time to take responsibility for that growth by being an active student. Do not be turned off by dress or remarks. Listen for the underlying message. You are there to learn. Take advantage of that time difference to Evaluate what you hear.
