I think it was March, 2008, before the 2007 Multiple Choice were released.
My student thought the MC were harder than the Free Response, which also has been worried. I assume that most of the MC are the same for the 5-year period. My students of the previous 4 years did not think the MC were that hard.

Hi. Since it's been since 2007 that the multiple choice were released, will the 2012 ones be released??
