      • AP Physics B Optional HW: Spend 35 minutes this weekend taking this multiple choice exam. Spend about 2 minutes per problem. Important: you will likely not finish on time, nor will you score particularly high. That's ok: more than 98% of students who got scores of only 35% on the multiple-choice section of AP Physics B passed the exam. If you get more than half right, you're in the company of those who got 4s or 5s on the exam. Grade your exam with this key written by Max, then turn in your graded exam to the inbox in Room 310 on Monday. Remember that your performance on these optional HW assignments do not affect your Physics H grades -- we want to look at your scores in order to figure out how to help you. Do not go back and correct your work in order to give yourself a higher score -- there's no point.
