That's awesome, congrats!!! I personally found it best to type my notes out on my computer during classes, mostly because it's just faster. Most, if not all, the class notes are in powerpoint, so there's tons of space to type your notes out in the little "notes" section in powerpoint. It was probably a 50/50 split between writing and typing in my class. And when it came to studying, I would just study straight off the powerpoint with my notes. You'll find out soon what's best for you!
As for the CNO exam, there is also a time in January/February where you can write the exam. The CNO just doesn't have that on the website now because it's already passed for this year. I finished the program in December 2017, and wrote my exam at the very beginning of February 2018, and once I passed, I started working right away. You can even begin to apply to jobs in January if you would like because a lot of places will hire you under the condition that you pass your exam. So you don't need to worry about that, you can write as soon as the end of January and then start working!!
Don't be anxious to start, everyone else will be feeling the same. The program is so small that you get to know everyone really well really quickly, especially all of the instructors and I think for me, that made all of the difference. If you have any other questions, I'm more than happy to help!
