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.

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!

Dear Professor,

You're skipping over many vitally important bits of information. For example, how exactly is stellar spectra taken. How is it performed and where are the results recorded? There is just too much information missing between the slides. Also, please try to speak more clearly -don't mumble or let your voice trail off toward the end of some of your sentences. Thanks!

Lessons contents are incomplete and quizzes are clearly above the level of the lessons. Don't know if I'm learning anything. I quit and will look to other alternatives as I don't want to waste more time and effort on it.

No real interaction, it's like sitting on the outside of a lecturer through an open window.....

You are assumed to know Science bachelors level math. When math is lectured there is no explanation of how it operates. The lecturer even says in one lecture that you should know this from your university physics. Not taught at all and glossed over and all lectures are a bit incoherent and not precise and all over the place. This lecturer is certainly not a teacher. I thought this was graded a beginners course???

Lectures are quite interesting, but the numerical exercises are a shit there is no way to really know how to put correctly the numbers, in spyte you could obtail the correct resultin your calculator. For that reason i will not recomend to take this course. REALLY BAD!!!!

En los cuestionarios, seleccionaba las respuestas correctas pero en la segunda pregunta no me contaba como buena (Aun y cuando salia la paloma verde), provocando la falta de ese punto.

Hard to listen to. Unlike other courses this course was just series of video taped college lectures. Very dissapointed

The difficulty contradicts Courseras slogan "education for everyone"

Too difficult for the non-science minded.

It's useless and lacking enthusiasm.
