Despite being the youngest member of the team, Khai has always shown himself to be a strong student. In the first national exam season, he excelled and won second prize in Mathematics. In grade 11, Khai continued to win second prize in the national excellent student competition. However, he failed both times in the selection of the national team to participate in the International Olympic Competitions. As a student who always yearns for victory, Khai admitted that he was very disappointed.

When he calmed down, Khai analyzed his own limitations and proactively adjusted his learning methods. In grade 12, for the third time participating in the National Excellent Student Competition, Khai surpassed his own limits when he won first prize with the second highest score in the country. For the third time participating in the national team selection, surpassing 46 other students, Vo Trong Khai won an official spot to participate in the International Mathematical Olympiad in Australia.

“Since I was a child, I have had a special love for numbers. The deeper I delve into Mathematics, the more I see its magic. The more I love Mathematics, the more I long to test myself in the international arena. The dream of wearing the national team jersey has become the driving force that urges me to strive every day. I understand that this journey is not for those who lack perseverance, but only for those who can keep the flame of passion, have enough determination and perseverance,” Khai confided.

Proud and moved

In preparation for this year's International Mathematical Olympiad, in addition to studying at school, Khai and the team members mostly focused on reviewing in Hanoi and studying with many leading teachers in Vietnam. In addition, timely encouragement from the leaders of the Department of Education and Training, the school board, teachers, family and friends helped him overcome psychological pressure, stabilize his spirit to enter the competition with the best mindset.

The male student said that the exam has 2 different rounds, the structure of the exam consists of 4 main parts: Algebra, arithmetic, geometry and combinations. Each part requires high levels of logical thinking, creativity and problem-solving skills.

“During the first exam, I was quite nervous. After reading the questions, it took me nearly 5 minutes to calm down. The exam was completely new and candidates had to use their knowledge, thinking, and creativity to find the answers. In the second exam, I was more confident. After more than 4 hours of taking the exam, I spent half of the time completing the first two tests. As for the combined test, it took me quite a lot of time because it required thinking, flexibility, and skillful application of knowledge,” Khai said.

With a total score of 38/42 points, Vo Trong Khai became the highest scoring contestant of the Vietnamese delegation and ranked 8th overall in this year's competition.
