Watch Bozeman Science videos. If you are a visual learner, or if you need a break from reading page after page of a chemistry textbook, give Bozeman Science videos a try. Mr. Anderson, the creator of the videos, explains the chemistry concepts you need to know for the exam in a clear, concise, and friendly way. He also includes slideshows and concept maps for each of his videos to help explain things further. The great thing about watching chemistry videos is that you can rewind if you missed something or need it explained again, pause if you need to digest something before moving on, and even fast-forward if you already have an understanding of a certain topic.
