I am 39 and taking marketing classes. I am old school, I took my iPad once and trust me.... nothing better than taking note on a real note book with a real pen. I still have my notebook with me in a drawer. When you have things into digital they get deleted and lost.
Take a notebook, improve your writing, improve your drawing, it will help you in the future big time and it cost a few dollars, do not brake and worry less.
I mean, if we had iPads in the 80's and notebooks today, notebooks would be the most efficient and fun way to take notes. iPads brake, get stolen, battery issues... buah!
For me, it really depends on the format of the class on how I prefer to take notes. Just as an example, a majority of my professors would create power point presentations for the lecture notes and what I would end up doing is printing them out 4 to a page, 3 hole punching them, and sticking them in a binder and taking notes directly on the slides. This resulted in me walking around sometimes with multiple 3 inch binders on days where I had back to back classes with no time to go to my car in between...and it sucked. Now a days, you can take notes and sync them to the cloud. If you are worried about them deleting, sync them to multiple places.
Don't get me wrong for classes like math and physics, I preferred the good old fashion notebooks. But most of my computer science professors went the route of power point or pdfs and for those classes...it sucked.
