This zipped file includes AP Physics with Calculus Mechanics free response questions, answer keys and presentations for all three free response questions in 2012. The files questions and answers are free from the College Board. The presentations are step by step solutions assembled in open document format (without the use of transitions to help with flexibility in assembling in your format). YOU can easily edit the presentation of this same material in whatever format you may use. The presentations are also provided in portable document format.
I found (over 30 years of teaching AP Physics) that student exposure to previous free response questions had a huge impact on exam performance. I would carefully review the questions and discuss solutions with the students but NOT allow them to take notes, copy or photograh the material. The next day I would use of the 3 questions for a quiz. Students that genuinely took part in the discussion would be best prepared for that quiz!
This collection would take 4-12 hours for a teacher to assemble and create personally. Use the time you save for family and fun!
