@hollystorm’s advice is solid. I would just add a few points to that: start early to get an idea of how much you need to cover, don’t discount Ethics, and get familiar with your CFA calculator as soon as you can.
Nov/Dec is definitely possible. I’d say take 2 weeks to research whether CFA is something you’d like to do, then decide/register latest by end of May to give yourself the best start.
If you have more specific questions, just start another topic!
