The course was very helpful to understand the concepts in chemistry and their applications. All the lectures were amazing. Thank you.

This is an extremely flawed course, both technically and academically. Half of the math used in the first week is incorrect (anyone using a calculator would discover this, but I also worked as an accountant for many years, as well as previously working in the financial markets as an investment analyst, so my math skills are above-average), and even when they made one correction in the video, they missed the other 20 or so. Even the textbook written by the professor has math errors in it (such as 12 X 0.99 supposedly being equal o 11.98 - not on this plant, or any other I know of, since it's actually 11.88). There are mix-ups in what shows up in what areas of the quizzes (such as Rutherford's gold foil experiment being in the first test, but the first week covers an entirely different area), and the first quiz talks about stuff that isn't discussed at all. Please explain how anyone would know grams per litre of SF6 at sea level when it isn't covered anywhere in the textbook or the lectures or the test itself. Not once did he explain the terms diatomic vs. monatomic (only the brief blip with Avogadro and how 'some molecules must be made up of two atoms then' as a conclusion, but no way to determine which ones, and not the actual meaning of the terms that ended up on a test). Nor does he talk about what (aq) is supposed to mean, where he uses it in brackets in an actual chemical formula. From my understanding of math, I'm supposed to be able to multiple aq by the rest of the formula, but since there is no element called aq, I have to guess that can't be right and it must mean aqueous solution, rather than a solid, but again that isn't even mentioned. Less than 2 seconds of time to explain, but the students are expected to search all over the internet for the answers. Um, isn't that the entire point of taking a class? So that that someone *teaches* the subject instead of students being forced to go to Wikipedia (which is generally frowned upon by academia)? Science is supposed to be accurate, and Rice is supposed to be a top university in the US. I weep for the entire country.

Excellent course, pleasant to listen to. Definitely improved my understanding of chemistry.

The lectures are great but something is really wrong with the quizzes. Sometimes you find in the test for week N a question which is to be covered only in week N+1. Often the questions are just unclear.

However, if you accept this fact as given and don't care too much about you score for the course, you may learn quite a lot. The concept development approach indeed promote a qualitative understanding and the material in the lectures is provided well and clearly. Simply the lector is good in explaining.

The quizzes are messed up (huge contrast with the lectures!) but they still made me to think and to recap what I have learned, so it is useful. This wasn't my first Chemistry course. I took it to straighten my understanding and it served the purpose very well.

If you only start learning Chemistry, you probably want better quizzes to monitor your progress.

Can I have the certificate of completion?

The course is really interesting with the concepts and application. I could able to learn many such in the basic chemistry. Since chemistry is one of the subject, which is inter related to our day to day life, the curse is very much useful.

I am really proud to be one of the learner!!! -Dr.M.Pandimadevi, Prof., Department of Biotechnology, School of Bioengineering, SRM Institute of Science and Technology, Chennai, India

I couldn't wait to take another module everytime i finished one..😍

I love to hear the detailed explanation to each topic's concept..

Thanks Prof. H..God bless you with so much strength and wisdom as you will continue to impart your knowledge to others! 🙏💓😘

Great course!! Very helpful and intresting method of study.

The best course to grasp the fundamentals of chemistry

Fantastic approach to concepts. Excellent instructor.

Excellent course. There are many questions to think.

Good Teacher, good Metodology, recomendated 100%

Awesome. I leraned a lot of this course.

course completed but no certificate

Excellent refreshing class!
