Syrian President Bashar Al-Assad's eldest son, Hafez Al-Assad, finished in 528th place out of 615 participants at the International Mathematical Olympiad, which took place last week in Rio de Janeiro, Brazil.
Answering only 14.17% of the questions correctly, Hafez ranked last in the Syrian team.
Meanwhile, Syrian student Mark Jabbour made the country proud and took home a silver medal.
The 15-year-old headed to the Olympiad, the global mathematics competition for high school students, with the Syrian national team, which traveled under high security.
With a cumulative score of 50%, the Syrian team placed 56th overall out of 111 countries.
The team's score was boosted by Mark Jabbour's 86.81% result, for which he won a silver medal, after winning bronze in 2016.
Since its first participation at the competition in 2009, Syria has won two silver and four bronze medals.
"I know what kind of man my father is"
Hafez's participation in the Olympiad has stirred quite the controversy, with many social media users mocking his results.
According to Brazilian news site O Globo, supporters of Bashar Al-Assad considered Hafez's participation in the prestigious event as a demonstration of his potential to become the next leader of Syria, as the regime describes him as highly intelligent. Meanwhile, opponents saw his publicly-advertised attendance as a "propaganda move".
Speaking to O Globo, Hafez defended his father, saying, "I know what kind of man my father is. As president, people say a lot, many are blind. But this [their accusations] is not the reality."
He went on to describe the Syrian crisis as a "war against the people," which he hopes "is nearing its end".
"The population and the government are united against the invaders who are taking the country," he said.
