Note that Kevin choked the 2018 MATHCOUNTS School round (reason is in his blog), so he did not make his school team in 2018. He made his own team with friends, instead of kids that are good at math, for ABMC in 2018.$^6$

Kevin moved into Lexington during the summer of 2018, and switched to Lexington High School in the fall for ninth grade.

"My ultimate goal is to get accepted into Massachusetts Institute of Technology or some other very good college, and from there, study mathematics very deep", said Kevin. He has now finished his third year of PRIMES STEP, a research program held at MIT once a week for kids grade 7-9. He got admitted to his third year without an admission test but got rejected from PRIMES.

Some more interesting facts

  • Kevin has 15 medals and 8 trophies from math competitions.
  • Kevin has scored $69 \cdot 2$ on AMC 10 twice in his lifetime, and that is his high score.
  • Kevin is now taking AP Calculus BC in school.
