You will have to play to the strengths of your professors and to your own strengths in note-taking. For me, I have some professors that have powerpoint slides that stand entirely fine on their own (which warrant no extra note-taking), whereas others have their slides more in an outline format (which warrant note-taking). Going off of what
@okramango said, I do the exact same. I do half and half. I am a type of students that absolutely needs to read the textbook for each class. Other students have found success on relying on slides only. Each student will be different
It is also important to realize that you will be asked to grasp material pretty quick, and you will need to latch onto that material since each class builds upon one another. That being said, make sure you to develop a good schedule that allows you to have a decent pace with your classes. Your goal will always be to 'not fall behind'. I have heard this, and since day 1 I honestly have never felt 'ahead'. So now that statement now translated to 'not fall too [far] behind'.
