10 months seems rather excessive, so be careful not to burnout. Take a few days or a week off here and there to recharge your batteries. Also, ethics once a week seems a waste to me, as you'll either spend way too much time on it (to the detriment of everything else), or you're not looking at it deep enough to get it. I'd read the handbook and the GIPs stuff once a month if you want to study it a lot- more than enough to fully understand it. However, you'll never kill ethics, it's like trying to hold a jellyfish, it's far to slippery. If you're consistently getting between 80-90%, then you're doing very well.

Quant is the best place to start as far as I am concerned. Good luck!
