Chemistry 20 Summer Class

Instructor: Alison Wang

Hi everyone! My name is Alison Wang, and I’m a current full IB student about to enter grade 12 this fall at Western Canada High School! I’m extremely passionate about the sciences, especially chemistry—I was a bronze medalist two years in a row for the Canadian Chemistry Olympiad, and received a special merit award for this year’s Canadian Chemistry Contest—and I really love talking to people about science (it’s about all I do as a science club exec). I’m so excited to be working with you all on the concepts covered in Chem 20, and I hope you’ll walk out of these classes with the knowledge needed to succeed in the course when you do take it!
