Skillful Quiz, the best understanding of chemistry. Although a little difficult to pass, U will be proficient in Introductory Chemistry.

This course is a cruel bait and switch. It's actually part two of a two-part course, but nowhere does it mention that. To begin, you need Introduction to Chemistry: Reactions and Ratios, by the same instructor. Otherwise you'll be left in the dust with tons of stuff from the first half you're required to know in this second-half course.

Three weeks of work wasted.

Amazing teacher with great practical examples of the abstract concepts covered, and an overall fun and interactive way of teaching. The exercises highlight the course material and rely strictly on it, with some additional but minor personal research.

Upon solving the exercises, they seem to additional reasoning and problem solving abilities.

The course is structured in a coherent and clear manner, each subject logically following from the other , and the ratio of learning content (videos & reading) to exercise content (exercises) is in harmony, and is a good ratio for an actual understanding of the topics covered.
