This site offers a 20 hour review of the NYS Physical Setting/Chemistry curriculum, but it can serve as a review for any high school level chemistry course. It is a crash style review of all that you need to know to pass the Regents, and any exam on the individual topics covered. Each unit is covered with a separate video presentation, notes to follow along and dozens of questions (multiple choice & constructive response) with detailed explanations. All you have to do is print out the notes and click on the video of the unit you want to review. You can pause, rewind, forward and replay the videos as many times as you want, at your own pace and convenience. The cost is $25 for one month or $75 for 4 months of unlimited access. Group rates are available. Just submit a request via the contact form.
PLUS, there are extended units on Organic Chemistry and Nuclear Energy which cover these topics in greater depth than on a review level. This is especially helpful to students who were rushed through these topics at the end of the year due to lack of class time.
