This is the third or fourth time I've reviewed this course but it still keeps asking me to

Great course, contents are very accurate and comprehensive, explained in a simple manner.

Course with deep notions. Prononciation can be difficult to understand.

Very knowledgeable instructor. A wealth of information in this course.

Exceptional for an intro course to astronomy,cosmology,astrophysics

good course. good content

speed it up to 1.5 - 2 x speed

I have really appreciated this course.

I found this course very interesting.

great course for physics enthusiasts

covers a lot of ground in short time

Great Content! Very recommendable.

Requires more reading matterials

It is good for biggners

Very nice!! Thank you!!

good course

There are number of positive things about this course but...

I'm only going to say about thing I don't like about this course;

1. Slide presentation; yeah it's now a norm but in slide presentation large amount of information flashed in your screen which is hard to track; there are some adventages of slide presentation but I prefer blackboard.

2. Derivation are not shown and that might be the reason you find it boring after some weeks and I'm not satisfied with the knowledge I am getting without derivation.

This course was very informative, but know that you definitely need to have some prior knowledge in physics. As a high school sophomore, I hadn't taken any prior physics classes and the class was extremely difficult. While I was ultimately able to complete the course and get a certificate, each week took much longer than advertised and it was very challenging. However, this class taught me about many interesting aspects of astronomy.

Good material covered. Very comprehensive. The courseware is not always working correctly. I completed the course, and it shows that I completed all the assignments with the green checkmarks, however it lost the grades for some tests in the first weeks, so it is not flagging that I completed the course. Some exam questions are also not working - there are discussions about this also in the forums.

Very useful and interesting course. It gives scientific answers to a lot of questions. The only drawback is that it does not offer a certificate and I believe that this is very important because it is the only one that gives this type of information about the universe.

Awesome course! Intensive learning. I recommend a few studies of astronomy before take it.

There are some issues with the feedback of others proffesors

So much handwaving! An introductory course for student who already know what the course is about... Yes, it's wrong.

the teacher is boring. other then that its an ok class. need to explain things more.

Probably a good course but by week 2 was way above my brain power!

require more efforts!

The course may be fine for engineering students and those who have a pretty advanced knowledge of Physics, but not for others. The answers to many of the questions on the quizzes and reviews were answered in subsequent lectures, rather than in ones prior to the questions. The lecturer was not very articulate, and when he corrected errors that he made in the lecture often was unclear about what he was correcting. otherwise, there was still some good information provided in the course.
