I will briefly outline what I did for step 1. I didn't take the USMLE, I only took the COMLEX, but the study schedule is applicable for both. I cannot remember exactly what I did for each subject but here is a rough estimate.
Anatomy: 2 days
Physiology: 3 days
Histology: 1.5 days
Micro: 3 days
Pathology: 4 days
Pharm: 4 days
Biochem: 1.5
I think it was very similar to that. Then I had a individual daily schedule that went something like this:
8-9am: Quiz/review from the day before (with study partner)
9-1pm: Study (audio lectures/First Aid)
1-2pm: Lunch
3-7: Study
7-8pm: Work out/personal time
8-11pm: Practice questions
That is what I did for 3.5 weeks. Then for the remaining 1.5 weeks, I went thru First Aid again and did practice questions. I did not take a review course or anything like that. I just had a study partner, Gold Standard CDs, my First Aid book and extra books depending on my subject at hand. For me, the key was practice questions. By the time the exam came around, I was doing over 300 questions a day. I bought Kaplan Qbank from COMLEX and did them religiously. I also had a classmate who had Qbank for USMLE, so we did questions together at night as well.
That is what worked for me. I passed (above average).
