I think that's completely misguided Maries. Making notes ahead is a great way to prepare you for the lessons that you will have, that makes classroom time MORE productive because you aren't trying to grasp the basic concepts, so you can just add to your knowledge. Yes, your teacher will give you extra information, so if you are making notes in advance you need to be prepared to modify them an ENORMOUS deal when school starts again, but I do believe that making notes ahead IF time permits, is a worthwhile measure.
