He was so good he was asked to perform at a number of festivals around Europe.
This year he was invited to the live auditions for the Royal Academy course.
"I couldn't believe it. I was stoked. I spent the entire summer preparing for it."
The auditions - which included around 30 people from all over the globe - went over three days and six stages.
"After the first day, we thought they'd cut it down to maybe 10 people. But a woman came out and read six names and that was it, the rest had to go home.
"I was the fifth name called out, and I just thought: 'Phew'!"
He was later told in an email that he was one of two people chosen to take part in the course, starting this September. The other successful student is a young man of similar age, Chan said, from Boston.
Asked what he thought helped make him a good conductor, he said he had one secret - listening.
"I think I'm good at listening; not just at what's happening in the music, but also listening to people who have been in the industry for a long time and are offering you advice. You need to enjoy [the performance] as well.
"As conductors, we influence the orchestra with little moves in our hands. If you're stressed, then the music is going to sound tense and it's not going to be a good night," he said.
"Other than that, I always have dark chocolate and a banana before going on stage - like a good luck thing."
Chan is planning to hold a number of shows to help raise money towards his fees, as well as living costs, which will cost up to $60,000.
