Dear Khan Academy,

I am writing this note to express my gratitude for Khan Academy. I am a high school student who self-studied all my standardized tests. Without your detailed explanation of Natural Selection, Calorimetry, and Differentiation, I would not have achieved my academic goals today. I sincerely appreciate your work and dedication towards free and high-quality education. 

Because of Khan Academy, I became a tutor on Schoolhouse for SAT Reading and Writing, sharing my knowledge with more people. It was 7:00 pm, and I opened an email about a shortage of August SAT R&W Bootcamp tutors. Even though I didn’t have previous experience as an English tutor, I stepped out of my comfort zone to teach others. This boot camp also helped me to familiarize myself with my second SAT. Through teaching, I fortified my knowledge and improved my speaking skills. It was more than a boot camp.

In the future, I want to continue contributing to society just like you guys. Once again, thank you for your work.

Best regards,

Chien-Yueh Liu
