Hi, I'm Erik. I am here to help you with Math - whether that is understanding a challenging concept, preparing for an exam, or working through homework problems. I've helped many students prepare for the SAT Math section, as well as in a variety of Math topics from classes ranging from Algebra 1 to Multivariable Calculus and Linear Algebra. I love learning about Math, Physics, and Computer Science, and enjoy helping others learn these subjects as well.

Integration Bee ∫ 2024 dx

An Integration Bee is a math competition where competitors race to solve integrals fastest. It might not surprise you that this competition originated at MIT, but now many other universities host Integration Bees as a fun way for people to develop their Calculus skills and compete against other math-lovers.

You can register as a competitor or a spectator and if you change your mind later, please send me (or another Calculus mod) a message so we can update your status for the tournament bracket.

Note: the start time and duration of this session are both subject to change. We know that any time we could host this will be inconvenient in some time zones, but we want to have a time that works for as many people as possible.

Thanks mate, you are so good at explaining that I learned where I need to work a bit. The session was needed. Best wishes for the future, and I really hope we can be friends!

I really loved how we were able to try tutoring. I learned how to better explain students why their answers might be incorrect. I feel much more confident about my SAT Bootcamp. Thank you!
