About me

Hi! I'm Minkyu (Andy) Jo, a senior at Renaissance High School. I've been doing competition math since 7th grade.

• 7th grade: USAJMO Winner
• 8th and 9th grade: USAJMO Honorable Mention
• 10th grade: USAJMO Honors, AMC 10 Distinguished Honor Roll
• 11th grade: perfect score on the AMC 12, USAMO qualifier

I'm also part of MIT PRIMES-USA, and these days I'm really into differential geometry. I've been to SUMaC and RSI too.

The site keeps a simple count of how many times each practice test is started and finished and each PDF is downloaded, so I can see what's useful. It's only totals: no cookies, no accounts, and nothing in them says who you are.

If you have a question, email me at andy.jo2008@gmail.com.
