Im studying for step II now, and did poorly on both OB and PEDS shelves (70 and 65, respectively).......Would it be too ambitious of me to read blueprints in entirety for both, or worthwhile? I have 17 days til exam and still have other things to study. Or is First aid + B and W + USMLEWorld sufficient for these even though i suck at them? Any advice would be appreciated! Thanks!
