Some of your teachers may be more technically-minded than others but here are a few suggestions to make them make best use of your iPad.

Or download materials before the lesson (especially if your class has a weak WiFi signal) rather than photocopy.

Most teachers will not agree to this but for 'lecture' style lessons consider recording what is said so you can listen to what is being said, only writing a few aide-memoires and then reviewing the recording for homework.

There are times when you will need paper but there should always be a reason for this.
