SDN Members don't see this ad. About the ads. I was browsing the official USMLE website and came across a section for MD/PhD students. They have a pdf file on their website: <a href="http://www.usmle.org/news/md-phd.pdf" target="_blank">USMLE info specifically for MD/PhDs</a> I didnt know this before, but apparently USMLE Steps 1, 2, and 3 must be taken within 7 years of each other. According to the pdf, some states will grant exceptions to this, but some will not. It recommends that MD/PhD students take the USMLE step 1 after their grad years (before entering year 3 of med school). Have any current MD/PhD students considered this? How do you find out which states will grant exceptions to the 7 year rule?
