Having seen the many comments concerning the M/C being relatively easy and the free response being very difficult, I make the following observation as one who has taught AP Calculus for many years--Calculus students almost always offer the same comment.
My concern having seen the Free Response and talked them over with my students is that they felt they needed to respond with extremely detailed explanations. I cannot blame them with no prior exams to guide their way; however, the readers for this years exam are going to have an agonizing task in front of them. I anticipate that the Board has not considered this and may well have far too few readers to do the task in the time allotted.
I hope that those of you who serve as readers will be willing to post your comments on this net as guidance to us next year.
Let me also thank everyone on the net for an extremely interesting year and offer my thanks for all the comments.
