Having no chemistry knowledge at all, i found this course very interesting but also very challenging. Such a sense of achievement now that's its done, and relief!

It is excellent course. Mentor in this course are very helpful. Teacher is also very good with her knowledge and there is no doubt about way of teaching.

This course was amazing.

It was my first online course and i am so happy to meet Professor Canelas and use her training.

Thanks for this amazing course.

Really great course! I have learned so much over the past few weeks. I would recommend to anyone that needs to freshen up their chemistry skills.

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.

this does not seem like an introduction

What can I say ..?! Things I learned or at least tried to understand but mostly failed 60 years ago ..by now explained..and..and understandable thus massive Wow..w´s at large..Thus only explanation must be the design of course and and just an dedicated excellentmaster of teaching....a thousand an one thanks

Fantastic and challenging. But to God be the glory. And its a course a scientist should take on. Love it.

Excellent presentation of the topics, easy to understand the instructor.

Clear and well organiz

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.

Explanations were easier to understand and it was clearly understood

it was a good interesting course the instructor taught very good

Очень доступно и интересно. Преподаватель позитивный.СПАСИБО

after submitting quiz please give answers with explaination

Great introductory course for refreshing chemistry concepts

This course has helped to understand the basics concepts .

Thank you very much, I have learned a lot of knowledge

Buena maestra se ve que es exigente pero es divertida
