I remember this same sort of thing for mcat-some poeple told me its better to take it in august cause the poeple that take it in august are the people who didnt get in or are the slacker people but some told me poeple in april is better cause teh people in august have all summer to study. I think when your dealing with that many poeple that take a step 1 and the fact that there are so many randomized questions, if you think of the chance of every single person getting a set of totally random questions, some of which they dont know and some which they do, times the huge number of people they will curve you against, i am saying no matter when you take it has gotta be the same but ihave heard otherwise. I keep hearing take it has early as possible but that made no sense to me as every school takes it at a different time. who knwos.. take it as soon as you can get ready i guess.
