They asked me 5 questions, I remember four. I can't remember the exact wording of the four but it went like this.
"What extra curriculars did u do and how does it relate to your passion in science?"
"Global warming or overpopulation, choose one and why?"
"Name a scientific principle, a device that follows that principle, and how does that device work"
"What is your favourite scientific topic, why do you like that topic?"
The fifth question which I can't remember was either talking about my school-life balance, or why I wanted to join JMSS.
