Words from Dr. Yi He’s students

Dear Dr. He,

AP Chemistry was a challenging class for me during junior year, but you helped me bring my grade up and understand topics more deeply. I am grateful that you helped me master complex concepts, showed me how to write good lab reports, and prepared me for the Chemistry AP test.

I really like your teaching style and how you always found a way to explain a difficult topic clearly. You also taught me how to approach experiments and lab reports like a college student.

Your AP chemistry test preparation class prepared me for the AP exam well, because you went over key concepts, assigned useful classwork/homework exercises, and explained complicated chemistry problems from mock tests.  

I also want to thank you for your encouragement throughout the year.        B.W.
