Here are some resources for your preparation for the AP Exam!
Official AP Chemistry Website - Here you have information about the details of the test, the topics covered in the class, what sort of calculator you need, as well as here where the free response questions from the last four years, with answer keys, are located.
Paul Groves Youtube site - Former AP Chem teacher who participates in grading the AP Chem exam. Good tutorials, walks through FRQs, etc.
Chemmybear - resource website for Paul Groves, has things like more tutorials, handouts, and graphics
Bozeman Science AP Chem - fantastic individual videos covering every single small topic in AP Chem. Great for last minute review of a specific idea or concept. (also has pages for nearly every other science!)
Bob Ayton's AP Chem site - Incredible AP Chem teacher in Florida (he makes Mrs. Julian look like a pile of garbage, OMG, he's so good). I especially recommend his three brief videos that cover review of all the main ideas in AP Chem. He also has planners and review outlines to prepare for the exam, but most documents are password protected. He also has videos on individual topics, like Bozeman Science.
Officially Sanctioned AP Review Slideshow (below) - a group of AP Chem teachers put together this super rad slideshow that covers, like, everything in the course. The presentation was so good that the College Board adopted it as "Official Review Material." Just click through on your chromebook!
Mr. Klamm AP Review - another teacher's website that has a slew of review resources. I particularly like the NMSI unit reviews (toward the bottom of the page) - good unit recaps.
Blog Article on AP Chem Review - has links to other resources, has some strategies, etc.
