You're probably finding this page because you're worried about taking the AP exam. Perhaps your frustrated with the existing online resources available, or maybe you're having a difficult time keeping up in class. Contrary to popular belief, the chemistry exam is actually quite easy to do well in, and this course will provide you with the steps and tools to succeed on test day.

Hello everyone.

My name is Sunny and I've been a professional Chemistry tutor for the past 4 years. As a 5-scorer on the AP Chemistry Exam myself, I've invested over 800 hours in tutoring dozens of students for their AP chemistry courses/exam. In 2019 I started RhomiTutoring, which provides online 1-on-1 tutoring to students around the world. By far the most requested subject amongst my students was chemistry, and particularly Collegeboard's Advanced Placement Chemistry. The combination of mathematics, problem solving, and memorization of the contest can make it daunting for many students.

At present, there are many educational videos you can find on the subject but few are structured in such a way that follows a detailed curriculum, and the vast majority don't provide practice problems to students, or the practice problems are simply not at the level of difficulty that would be needed to achieve a 5.

That's why this course was designed to have an emphasis on problem sets. It contains 6 broad topics, with each topic containing quizzes, lectures and 40+ exercises, along with 10+ hours of lectures and 12 problem sets.

1. Mathematical Foundation for Chemistry

2. Chemical History and Elements

3. Stoichiometry

4. Kinetics and Thermodynamics

5. Equilibrium

6. Acids and Bases
