    A nine-year-old child will become the youngest ever person to complete a university degree.

This December, Laurent Simons will gain his electrical engineering bachelor's degree (学士学位) from Eindhoven University of Technology, a challenging course even for 18-year-olds. It has taken Laurent only 9 months to complete what should be a four-year course. Laurent's teacher said, “He is three times smarter than the best student I have met in my long working experiences. He achieves what many adult students never reach.” The young gifted child finished easily the entire primary school courses in only 12 months and then took just 18 months to complete his secondary school studies. Laurent comes from a family of doctors, and his parents cannot offer any explanation as to why their son is so academically gifted. Every time he can pass every test effortlessly with flying colors.

While Laurent is clearly able to learn faster than most, his parents are being careful to let him enjoy himself too. His father said, “We don't want him to get too serious. He does whatever he likes. We need to find a balance between being a child and his talents.” Laurent enjoyed playing with his dog Sammy and playing on his phone, like many young people.
