This zipped file includes AP Physics with Calculus Mechanics free response questions, answer keys and presentations for all three free response questions in 2013. 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) YOUR presentation of the 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. This collection would take 4-12 hours for a teacher to assemble and create personally. Use the time you save for family and fun!
