Richard Chen has excelled so well on the American Invitational Mathematics Examination (AIME) that he has qualified for the United States of America (Junior) Mathematics Olympiad (USJAMO). Only about 500 students among the thousands of AIME participants qualify. This is a prestigious honor. The USJAMO is a rigorous 9 hour exam divided into two 4.5 hour assessments of extremely rigorous mathematical proofs. Good luck to him!
