challenging. well organized complex information. i learned the subject matter by working through the problem sets. my thanks goes out to the professors! this is a difficult subject to teach.

Excellent course. If you are struggling with high school chem, or need a good foundation for college chem - this course moves you through the concepts and gives you lots of practice problems.

The course was very helpful to understand the important and basic concepts of chemistry. I enjoyed doing this course.

I didnt get my certificate,please tell me the reason
