Amazing resource. I recommend starting with this course + Susskind's theoretical minimum. You can go anywhere from here:D

Lecturer is very difficult to understand, lectures do not seem to flow well

It's very interesting course. I get understading about quantum mecanics in short time. But at week1 will be very useful give more information about complex number and at week4 some examples of propability calculations and vector description of two spin states.

A good introduction to quantum mechanics that does not require excessive mathematical skills.

The course starts getting complex pretty fast. Although the professor says it's an introduction to an introduction, it throws mathematical details at you. Week 1 is straightforward and encouraging; nonetheless, if you plan to get an overview of Quantum Mechanics and atoms, it is a good overview to navigate your learning.

It was a great experience to have this course. The instructor taught in an effective way. The course is extremely useful for learning quantum mechanics. This course really developed an understanding of the subject. I am thankful to Coursera and HKUST for making such a course.

Quite an interesting class with an extremely passionate Professor (Instructor) of the course: Understanding Modern Physics II: Quantum Mechanics and Atoms

A gentle, but fascinating introduction to quantum mechanics. The lecturer did a phenomenal job and the assignments felt challenging but fair. Really good!

I extend my thanks to speaker for the elaboration of the content in a systematic order.

Very nice and brief introduction before learning quantum mechanics...

well explained.

thank you
