New science curriculum with hands-on learning, coding and food literacy gets top marks locally. By Kate Dubinski · CBC News


Mr. Sun is very friendly and makes learning so much easier. He goes through each point thoroughly and will always make sure that all of the students understood clearly. Amazing teacher.

Strongly suggest you try it if you want to learn any programming language or computer science! Trust me, programming is hard but Teens Programming made it an easier experience for me.

Napu taught me a couple of years ago and was very kind and professional. I have heard many great things about this school recently and I am glad to hear that the quality of his teaching is still among the best I have ever had
- Jason L
The course offered here is organized and covers various computer science and coding topics. The contest course will prepare you well for CCC and any other computer contest. Learning from Teens Programming definitely prepared me well for high school computer science class and helped me get my offer of admission to UWaterloo CS, CFM and CE. Overall I highly recommend anyone interested in computers take classes from Teens Programming.
