AP Chemistry Summer Crash Course


Hello everyone! Will you be taking AP Chemistry this year? By joining my series, you will review the whole curriculum this summer! NO prior experience is needed! Doing so will give you a strong understanding of AP Chemistry when school begins, and you can succeed in the class! In each session, we will get an overview of the unit. We will begin with easier practice problems to gain a basic understanding of the topics. Then we will progressively move our way toward more challenging ones to solidify that understanding. AP chemistry is a daunting course that may be difficult to understand. If you have any questions, please do not be afraid to ask! I was once in your shoes as a chemistry student and completely understand how you feel. Please don't hesitate to reach out to me, and I can schedule office hours in your free time! NOTE: TIME LISTED NOW MAY BE SUBJECT TO CHANGE. Who is the course is for: - Motivated and hardworking learners (There will be a lot of information, and slides will be posted after each session) - Students taking AP Chemistry this coming school year About me: - I am a rising senior in high school. Hopefully I won't be too intimidating like a chemistry teacher ;D - I took AP Chemistry in my sophomore year and earned a 5 - I have tutored AP Chemistry at schoolhouse throughout my junior year, and I have incorporated feedback from there to make this series even better!

When we had questions you made sure to slow down and explain them to us, and the explanations were very helpful for understanding the subjects. The practice questions were also a really good tool!
