The only way to study for Step

Step 1 is a huge test.  If it wrecks you, your chances of matching into the field or institution you want drop drastically.  I don't mean to scare anyone, but it happens.  On the bright side, the Step 1 score isn't everything, depending on the program you're applying to.

The only way to study for Step is to use the method that has worked for you during med school, with some adjustments for covering the material as much as you can.

The key isn't going through First Aid 1000 times like that one arrogant, insufferable and boastful medical student does.  It doesn't count how many times you go through study material if you're not memorizing and learning a little bit more everyday.

Tip List:
1.  If you've memorized First Aid for Step 1, read through it for review and focus on UWorld.
2.  UWorld tests your knowledge and recall and helps you see if you really understand the mechanisms of things.
3.  Mechanisms are key.  Know why a disease has this feature and that feature.  Know why this medicine harms or helps a patient with this condition.
4.  Step 1 nowadays is REALLY clinical.  Not in the sense of managing a patient in a hospital, but you have to tie together basic sciences with pathophysiology and patient symptoms and presentation.
5.  Studying for this exam can feel awful, but it's pretty cool when you start filling in all the blanks in your knowledge.
6.  You're going to be pressed for time when it comes to studying, so triage your subjects by how well you know them.  And by how well you know them, I mean how well you do on the UWorld questions and how well you have memorized them in First Aid.
7.  Don't read an entire separate pharmacology or embryology review book.  I can't tell you how insane that is.  People who brag about reading 5 other books on subjects are idiots with an approval-seeking problem.
8.  Regarding how long to study:  Don't be immature and say you're "going crazy from so much studying," and then take the exam before you're really ready.  Take your time, and consistently balance reviewing with learning new things.
9.  Know how things in medicine oppose each other.  I don't mean docs and insurance companies, but rather, antidotes, and how medicines affect organs, bacteria, vitals, etc.
10.  Get familiar with all the classic waveform patterns for the right atrium, cardiac cycle, pulmonary function tests, etc.  Know how to tie the changes in physiology to a graph/waveform. 
11.  Don't ignore biostats or behavioural sciences. 
12.  Spend the last week speed reviewing everything you're not solid on.   Shooting to finish  in depth studying by a week to several days before the exam reduces cramming and helps you relax more. 
13.  If you feel that working out stresses you and takes time away from studying, that's okay.  This is a big test.  Get that bikini body later.
14.  Sleep well every night.  Each study day will yield more

The Big Day:
1. Bring comfort food and fluids.  I liked bringing pizza from my favourite pizzeria, gummy bears, pumpkin seeds, and some coffee.
2.  Eat well and sleep for at least 8 hours the night before.  Actually, sleep well the entire week leading up to the exam.  That last week should be just for review.
3.  Break time happens between blocks, and it accrues.  I took my first break after the 4th block or something, so I had time saved up.  But I kind of paid for it because I had to start taking breaks almost after every block.  It

Step 1 is a long exam, but it'll feel even longer if you don't prepare right.
