I only have on hand (arm amputee) and in undergrad I had to have surgery on my wrist. It was only undergrad, but profs were very accommodating in letting me record class if I asked. Make sure you focus hard during class- it was easy to get distracted when not actively writing. (It will be good that it will happen at the beginning of the semester and not during exam time). I also learned how to type with my toes for emails and such, but you wont need to do that since you still have one hand.
Wow, you're an impressive dude. I think you nailed what worried me the most, maintaining focus and not falling behind. I guess its really not too bad, especially since I don't have to get acclimated during finals. I wish you the best of luck and thanks for putting it in perspective.
