How does the difficulty of a given MCAT version affect your score? I took the MCAT on 9/1/12, and from what others are saying, the BS section was significantly harder than what people had on other dates. Is it better to have a harder or easier test? Some people say that they did not have time to answer some of the discrete Qs at the end of the exam...will this be taken into consideration for the curve, or is it pre-curved? Thanks.
