About

We'll be learning Geometry through the use of Introduction to Geometry by Richard Rusczyk, published by the Art of Problem Solving. The textbook we're using really helps you get a rock-solid foundation in Geometry since it includes many challenge problems! Join if you want to be challenged.

We hold TWO sessions of the same chapter each week. These are:
  • Friday 10PM EST (starting 8/22)
  • Saturday 7 PM EST
You may choose to attend EITHER session. Don't attend both (unless you missed part of one of them)

Hi everyone! I'm Divya, a freshman in a public high school. I love reading, writing, cats, badminton, and performing arts. I'm super excited to learn and teach at the same time! I'm hoping to study and prep for the courses I will take in school next year, as well as the SAT. I was a part of my school’s MathCounts team (top 10 in a school of a 1000) and we recieved 2nd place at the Chapter competition. I am currently a MathCounts coach. I love challenging myself through problem-solving and competitions like the AMC 10. I also sing and have a huge interest in musical theatre. I am currently studying for the AMC 10. I do competitive dance and I also perform a lot in theatre and singing. I'm so excited to be here - can't wait to learn with you all!
