In order to get an “A” in chemistry you need access to high quality instruction, examples, and lots of practice. Through videos on my YouTube channel, and content on my website at www.Breslyn.org, you’ll have the tools you need to be successful in general chemistry.
Note that about 25% of people (in the US) who take general chemistry don’t pass. Many even end up changing their majors from science or medicine to another field.
For each section on Breslyn.org there’s a video, practice with immediate feedback, and links to specific content in quality online open textbooks. I recommend you watch the video, practice, and consult your textbook or one of these free online texts if you need more help.
