From teaching secondary school physics to launching satellites into space

SAT across from a couple of Ministry of Education (MOE) scholarship interviewers was Mark Lim Jian Wei, with his A Level result slip laid on the table between them.

From the get-go, he knew he wanted to be a physics teacher. His goal was to inspire kids to create innovations that make a meaningful impact, because he felt he could only do so much on his own.

So when the interviewers asked what he wanted to teach, he replied: Physics. They pointed at his results and said: "But out of all your grades, you did the worst in physics."
