I have been teaching AP Calculus for two years now and I have one quick question regarding the multiple choice section of the AB exam. Is it better for students to make an "educated" guess for problems they are not sure of? Would you recommend that they leave that question alone and not mark anything on their answer key? I remarked to my students that I would not leave anything blank and make the best possible guess.
If anyone can bear any light on this, especially those connected with grading the exam, I would appreciate your feedback.
