Okay so here's what I found with taking notes in classes with this tablet. I am an avid fan of taking notes with my tablet. I used to do it on my Galaxy tab 3 7 inch but I found that I needed drawing capabilities because I'm an engineer and drawing out the free body diagrams on the board was nigh impossible. So I bought the Tegra Note 7 for its stylus and awesome processing power. Here's what I found through taking notes on tablets (both the Galaxy Tab 3 and Tegra):
1.) It's not paper. It won't feel like paper. It won't act like paper. You can't move it around like paper. So trying to take traditional pen and paper notes on a tablet is not feasible, even on the more expensive Galaxy Note tablets. We're just not at that stage of technological development yet. That doesn't mean styluses don't have their use though.... (I'll explain later on)
2.) If you want to take notes on your tablet, invest in a good physical bluetooth keyboard. This is so much nicer than trying to type with the on screen keyboard. Heck, I've even stopped taking pen and paper notes because its so much easier, faster, and more useful to type out notes than handwriting them. I use evernote. This syncs all the notes I take to a cloud. That means I can access those notes on my computer, my tablet, AND my phone. Without having to rewrite it or downloading it manually to every device. This is so useful when you're taking a poop and you're like, oh hey I can use this time to study. Just pull out your phone and boom! all your notes right there to read during your... lets just go with leisure time. So invest in a good physical bluetooth keyboard. And not one of those crappy ones that come with the cases. I use this one: Logitech 920-003390 Tablet Keyboard for Android 3.0 Plus.
3.) So what is the stylus good for? I find that its useful for more annotating PDF files and pictures. If I have time to prepare for a class before hand, I'll go through the professor's lecture and put in a base guideline for what my notes will look like. I'll place all the images that he/she will talk about and I'll pretype out notes for what's going to be said. Then during lecture, I just make adjustments to my notes as the professor talks. When he comes to a diagram or photo, I pull out the pen, and use the annotate feature on evernote to highlight or draw on important parts of the figure. This only works with classes where the professor gives out the powerpoints before class however.
So thats how I've been taking my notes. Hope it helped you decide!
