AP Preparation


  • College Board--Sample Questions
  • 2008 Multiple Choice Test (in class)
  • Review Packet
    This is a handout from a teacher in Texas.  It has a lot of information.  If there are topics that do not look familiar, they have probably been dropped from the revised curriculum.  This might be a good place to remind yourself of all the topics we have covered.
  • Mr. Ku's Tips on AP Preparation
    This is somewhat outdated because of the new curriculum (and the link to practice exam questions doesn't work anymore) but the idea about "cheat sheets" is good.  This is a useful plan to prep for the AP Exam.
  • Bozeman Science Videos
    This teacher has made tons of videos (about 8-10 min each) about all the topics in the newly-reorganized AP chemistry curriculum.  The new curriculum is organized into Six Big Ideas.  We have covered all the Big Ideas except Big Idea 2.  You could watch videos for topics you feel rusty on.

To Do:

  • Make a calendar of tasks from now to the AP exam.
  • Collect useful materials from each chapter such as Nine-Station Reviews, Study Lists, and Practice Tests
    Check out the AP "Lockers" for chapters you cannot find.
  • Make a "Cheat Sheet" for each chapter (see Mr. Ku's Tips)
  • Try as many FRQ's and MC Tests as you can find.  We will hand out two before break and more when we return.
  • Do problems from your AP Review Book (Princeton Review, etc.)
  • Watch some of the Bozeman Science Videos to remind yourself of topics on which you are rusty.
