Viewing work
View your work on your computer - the bigger screen is normally best.
Typing work is generally easier on a computer.
If you have to do work in OneNote - you could try your phone but the screen is likely to be too small.
Submitting work
If you've typed up a document then it's much easier to submit using your computer.
If you're written work in a jotter, your phone is actually best - it probably has the best camera and is easiest to hold
