I have enjoy the format of this online collection of solutions for College Physics Answers. Having tutored math students over the past 10+ years, I recently offered assistance to one of my past Calculus students this summer while she was taking a two semester Physics class at my alma mater, Loyola University, New Orleans. During my time as a math major, I always took the opportunity to purchase the student's solution manual for my math textbooks when they were available. I have always held the opinion that this is not a 'cheat' but more of a silent tutor that one can refer to when the set-up or execution of a homework problem wasn't clear. Many years have past since my earning a bachelor's degree, so when it came time to assist the Physics student I was tutoring, it became clear to me that I had forgotten some of the finer details in the subject of Physics. Loyola chose to use the OpenStax College Physics textbook which brought me to the discovery of your "College Physics Answers" online. It not only gives the answers, but provides the full explanation of each step in the process. Better yet, is the video presentation that helps build confidence in solving the problems. Once again, congratulations on such a skillful publication and video presentation.
