I agree with Ron Burgandy on this and would like to add a little. Identify your weaknesses before you start studying & allocate more time for them. Don't spend the same amount of time on all subjects if you're stronger in some than others-that just doesn't make sense.
I felt that I needed a good foundation to start doing questions, but everyone varies here. I don't like getting 50%'s on sections before I was ready, b/c it's just a blow to the confidence. Put a little time in, start phasing in questions, then convert to mostly questions with a little review. I can vouch that First Aid for Step 1 was very good, but everyone has their faves. Ones I'd recommend-BRS for Path, Kaplan for Biochem. The rest you will get from QBank. Also, I reviewed Micro & Pharm with a study partner a little each evening, b/c studying 50+ drugs or 50+ organisms/day just won't stick.
In the end, everyone has different techniques that work for them. I'm a poor crammer, so I went with the methodical approach.
Good luck.
One of the myths that has seemed to perpetuate along the trail is that with so many applicants, if you're not from a top 10 school, your Step 1 scores are what separates you from the pack. Also, regionalism is alive and well. I thought it was all BS, but if you're really interested in going somewhere that you have no ties to on your CV, do yourself a favor & rotate there.
I don't envy you...I can still remember the day I took it & thought I went 10 rounds with Mike Tyson.
