Any useful iPad apps for college?

I was thinking of getting the new iPad Mini 2 when it releases but I was wondering if there's any useful apps I could download for college? Plus, is it good for reading? Cheers :)

I couldn't tell you if the iPad mini 2 is good to read on as I'm not aware of the specs, but I can tell you I've been a little disappointed with the current iPad mini's resolution. I use the Papers app for storing and reading scientific papers, but I have difficulty with the smaller fonts in some of the PDFs (when at full screen). Unless the mini gets a bump in resolution, I'd recommend the larger iPad if you plan to use in a similar way.
