July 2022 Invited Speaker at Benchama Maharat School

Summer teaching, Benchama Maharat School, Ubon Ratchatani, Thailand, 2022

I’m very honored to be invited as a lecturer to help prepare high school students at Benchama Maharat School for the POSN 1 camp this year. For those who don’t know, POSN 1 is the very first regional round which leads towards the International Mathematical Olympiad. I taught the students from July 1st to August 15th, which was during the time I visited my home in the summer. The duration was short, but we did cover several topics that appeared in past exams. Most of the problems are from POSN1 problems in 2019 and 2020 on this website and also from the AMC12 problems. Please visit this page from the Art of Problem Solving website for its incredible collections of AMC12 problems and solutions.

Here are some photos of my students and me in class. My class was from 7:30 - 8:30, which is basically the so-called 0th class of every day. We might look tired but were actually full of energy!

The following are all of the worksheets and solutions that I used to accompany my class.
