Thanks Dr Canelas! You gave me confidence.

so useful, and a professional teaching way and a genius professor.

When I entered this course, I wanted to expand my knowledge on the foundations of Chemistry. This course helped me to do that and much more. Through this course, I was challenged enough that I can confidently walk into a Chemistry classroom and ace the pretest. I recommend this for anyone who is trying to get a degree in anything branched off of Chemistry.

I would give the course 4.5 stars if I could. The course is a great introduction into Chemistry and I really enjoyed it. Professor explains non-trivial topics in lovely and easy to digest way during first 4 weeks. However, the course shifts gears in weeks 5 and 6 and I had to watch lectures twice to fully understand concepts. Moreover, to solve advanced problem set for week 6, I had to read about Ksp calculation outside. Apart from this inconvenience, the course and professor are great.
