One middle school student in Georgia got the highest score in National Middle School Bio/Chem competition after taking USABO and TJ summer chem class 2023.

One student in CA had a consulting because parents thought that the student was behind everything. The student was too smart and did not want to talk with normal people. The student got MENSA membership and reviewed all the recorded USABO/Chem class 2022.

Ones student in Florida took USABO/chemistry class in 9th and made both chem/bio Olympiads 2021. 

One student in Texas got the highest score in 2020 USABO first round exam.

One 7th grader in Idaho took TJ summer chem in 7th, took AP chem in 9th and passed Chem Olympiad.

One Langley HS student in Va took chemistry and passed chemistry Olympiad, 2018. 

One 7th grader started USABO from 6th, is taking USABO class and understands very well.

Some smart students failed TJ for no reason. Then, instead of disappointing, start chem/bio/physics/math for Olympiad and passed, resulting in a dream school.
