Hai Tran


Hai graduated from UC Berkeley with a bachelor's degree in molecular and cell biology.  Having been a teaching assistant for math classes in high school as well as a biology lab course in college, he enjoys figuring out how to help students learn in ways they can easily understand.  Hai struggled in math at a young age but made a remarkable turn-around towards the end of middle school.  In high school, math became his favorite subject mainly due to the teaching methods of his teachers.  He knows that no matter how much a student dislikes doing math, there must be a way to teach it for them to enjoy learning about it.  In the future, Hai plans to pursue a health career as a physician's assistant.
