EM Semester Review

The main topics are listed below. Keep in mind this is covered in chapters 21-26. There are numerous worked examples and odd problems we can try, along with chapter review pages. There are videos on just about every topic. There are AP Free Response Problems and Solutions  (including a multiple choice folder); be sure to be logged in with your eths202 account for access. There are review sets in each topic folder on the school web site. There are practice problems and notes on the SAT II website. There is practice materials at the Learn AP Physics C site. Get into a study group. Come in for AM Support or lunch periods. Review old quizzams, HW sets. Review the essential questions you've received for each unit, and the objectives file. Review the equation sheet. Lab questions and concepts are fair game.
