Well. . . to do great on Step 1 you basically have to know all the information that they are covering in your classes second year (Path, Pharm, etc...). So, for the first six months, I basically studied hard for my classes and tried to do well on the exams. I didn't necessarily do special preparation for Step 1.
For the next 6 months, I stepped into high gear studying for Step 1. Bascially, I figured that my next 6 months of grades were not as important as Step 1 in 6 months. So I used the following resources: FA, Step-Up, BRS Path, Gold Standard Audio, Underground Clinical Vignettes Step 1 (highly underrated - and a great resource), and questions (taking a practice test and scoring myself once a month looking for improvement).
I went through all of these resources multiple times (at least three) during that six month period. I don't want this to turn into a discussion on reading vs. audio - but I made audio versions of all the books and actually listened to them (it fit my learning style).
So, at this point, I was familiar with all of the resources I would use to cram for the last month. At my school, we all took Step 1 at the end of the second year (M2 year). Like many schools they gave us the summer off (6 weeks). So I studied in a cramped little study carrel from 8am to 8pm for 4 weeks, took the exam, and took 2 weeks off.
There several keys that will help you along the way.
1. If it's important, it's in a lot of books (FA, UCV, Step-Up, and Gold Standard). You go through each three times and they all mention one important topic - you hear it 12 times and remember it!
2. Pick a few resources and get through them at least three times before trying to "memorize" anything. If you do the above and hear about Fabry's Disease 12 time, you won't have to sit down and memorize it - you'll already know it.
3.Don't get bogged down. 5 pages a day while trying to memorize will never do. Burn through the material.
In summary for your MSII year:
First 6 months - study to do well in your classes (this will be the same material for Step 1).
Last 6 months - transition to your Step 1 resources (this will be some of the same material you need for classes).
Last 4 weeks - cram. 12 hours per day, every day. Know your Step 1 resources forward and backward.
Finally, take 2 weeks vacation.
