Do you need to take Step 3 or the score prior to applying for cards fellowship or can you take it in interview season? Does this put you at a disadvantage (i.e. do you get screened out by various programs for not having taken it)? Last time this question was asked was in 2013, wanted to see if things had changed since then (http://forums.studentdoctor.net/threads/need-step-1-2-and-3-to-apply.984672/)
