Hi! I'm Kaleb, and I'm currently a homeschooled high school student. I love math, participate regularly in various math competitions like the AMCs, and I'm always excited to share this love with others! I'm a 4x AIME qualifier and also qualified for USAMO this year. I help coach a middle school competitive math team and often discuss math with others. Some of my hobbies include listening to and making music, reading philosophy, gardening, and photography.

Here on, I serve as moderator of the Pre-Calculus Subworld, and was previously a member of the advanced peer review team :)

Competition Math Advice / Q&A

This session was requested by Ariel L but anyone is welcome to join. The time will be quite informal and we'll be having conversations about high school level math competitions (esp. the AMCs and AIME), and everyone is welcome to ask questions! I will try my best to answer them, based on my own experience.

Thank you for the amazing suggestion and prep. You explained the problems in great ways and let me leave with new knowledge and ideas on how to approach problems.

The best series I've done. The way you explain things helps a lot. Thanks and have a good summer.

Hi Kaleb! Thank you so much for this super helpful session. I wasn't really confident in writing equations from trig graphs prior to this session, but now I know what I'm doing. I appreciate your help and I look forward to attending more of your sessions in the future! :)
