Need Advice

So I’m currently approaching the half way mark as an OMS II, looking to take the usmle and comlex sometime within the next 6 months or so. I’m pretty set on ortho as of right now and I’m looking to do better on my comlex cause I figure a high score on that will open more doors for me with AOA residencies v.s. the same score on the usmle with allopathic residencies (especially since I want to do ortho). So I was wondering if anyone out there had any advice as to when I should start studying for these two exams, how much time I should give myself in between exams, and if anyone had a schedule that they found very effective I’d sure like to hear it. Lastly, any advice from fellow osteopaths or allopaths will be greatly appreciated. Thank you for you time!
