I would like to take some sort of classes for the step 1 to refresh my knowledge as its been a while since i graduated from med school. I am an img. I was wondering if anyone could help me decide which one to take. There are s many out there that i am confused. I am more inclined towards the kaplan but am not sure whether to take 7 week or 14 week course as i am an img and am am weak in basic science.
