So I was looking at threads with recommendations for the IM shelf....prior to the release of MKSAP for students 3, MKSAP 2 was apparently considered the best resource....a ton of posts here along the lines of "MKSAP 2 is all you need." More recent threads that came out after MKSAP 3 was released have a lot more comments like "total waste of time, not helpful at all for the shelf." So I was doing MKSAP 3 today, and switched over to MKSAP 2 to do questions on the same topics....I've scored significantly lower on the same topics I already covered on MKSAP 3! Did MKSAP get easier with the release of version 3? The only other explanation for the change in people's enthusiasm about MKSAP would be if the shelf is harder now than it was 3 or 4 years ago. Based on what I'm seeing, the MKSAP questions seem to have gotten easier though....although I don't have MKSAP 4 so who knows. Thoughts?
