I’m knocking this course down one star because of the numerous errors in the practice problems and a few on the quizzes. And this is mainly because, judging from the dates they were addressed in the discussion forums, the errors have been there for several years and have never been fixed. They are small errors ranging from having a minus sign instead of a plus sign in front of the correct answer on a quiz, to one of the practice problem worksheets missing the second half of information needed to calculate the equation (which confused me until I finally caved, looked at the answer key and found it on there). These errors seem minor but for are confusing for someone who hasn’t taken a chemistry course in over a decade and wants to make they are going through and understanding the material correctly. Other than that, it was a great course and a great refresher.

I enjoyed the course content very much. It was a great overview of basic atomic structure theory and the basics of stoichiometry and reactions. I'm looking forward to the Advanced Chemistry course I'm doing next.

There were quite a few errors scattered about, but that's not such a big deal.

There was one question in the final text which is just wrong -- I left a post in Week 7 Forum. It's question #9 - what energy is associated with the process X(g) --> X+(g) + e-? My (correct) answer was "first ionization energy" but that was marked incorrect. I even tried going back and changing my answer to "electron affinity" (which is related but is not an energy, per se) but that was rightly marked incorrect too. So I didn't get 100% on the test and I'm not going to just keep randomly guessing other answers to get a "correct" response.

Most of all the subjects are explained very thoroughly, however there were some instances where some examples were not explained period, which effected my understanding of certain concepts. Overall, the course is very good and recommendable for those who have an easy time learning, but those like myself who need many examples for every type of equation and whatnot will have a rough time.

Very insightful and informative. The instructor was extremely thorough with her explanations which allowed for easy understanding. This course covers various topics that act as a good extension to the IBDP Chemistry syllabus. So grateful to have found this course and am willing to do more in the future!

In the quiz test, most often I have to recalculate my solution till I can get a match in the answer selections. That process greatly improved my comprehension of the concepts of that particular chemistry topic.

I love the resources (slides, questions). I found thermochemistry the most challenging- a recommended textbook or additional resources would be helpful in this section.

لقد كان هذا الكورس الخاص بالكيمياء رائع جدا ،تعلمت كل شئ يخص الكيمياء العامة ،إنه حقا مفيد ولكنه صعب بعض الشيئ،شكرا كورسيرا وشكرا لمنظمة تجمع الشباب السوري

Good course, however formatting on exams was sometimes extremely detrimental to learning. (e.g., almost no tables are used.)

El curso estuvo muy bueno, un poco complejo.

Por favor podrían ayudarme con el certificado. At, Nely Vallejo 1711426161

Good course for high school students or college underclassmen to refresh on chemistry knowledge.

Needed external course matter help for clarification purposes. Otherwise, excellent content .

Great course for after/during school on advanced chemistry. Interesting and manageable course.

Good course, well explained. Errata could be included in slides, or put on the videos.

The course was easy to understand. Clear explanations provided.

This course teaches me the basic about chemicals reaction,etc

Me ha ayudado mucho este curso para mi evaluación de química

GOOD. BUT CERTIFICATE NOT GENERATED FOR ME AFTER COMPLETING
