This course finally mitigated my immense interest about Universe. I really liked the content and evaluative process of this course. Thanks to Caltech for this amazing astronomy course.

I really loved the course!

The explanation was clear, and I loved the way the professor added information between the texts! A must-take course for every astronomy aspirant!

Amazing course. Gave a complete overview of entire universe. Just perfectly what I was hoping to learn from the course. Very interesting.

Muy buenas explicaciones, temas interesantes, y diferentes puntos de vista para comprender mejor lo mas posible de todo el universo.

Me gustó muchísimo, aprendí bastante sobre todo lo que quería aprender de cosmología. Ahora a seguir profundizando!

A bit dry, but so vey interesting. Thank you very much for the course. I loved the Course Cal Tech.

Impressive. You can learn a broad range of things and get an insight into the universe.

Useful for every beginners starting to follow their dream of astrophysics

i really really love it... its highly inspirational!!!!!!

Very nicely planned and covered all the important topics.

Amazing introductory course to astronomy. LOVE IT!

Very useful and much needed for beginners.

Excellent course and highly recommended.

Thank you for the really nice course!

Learn a lot in very little time.

GEORGE DJORGOVSKI IS THE BEST.

Great Course and content

Excellent course overall. I learned a lot and it sparked my interest to study more about astronomy. The only caveats I have to offer here are that this course is not for total beginners: a student really needs to have a background in basic calculus and physics in order to get anything out of the course. Sometimes it feels like the professor is presenting results at a research conference rather than teaching students with no astronomy background---which can be exciting to watch but it can also be baffling to beginners. Also, I felt the course presented a little too much material for a single session, perhaps the course should be split into two parts? Other than that, highly recommended.

Prof Djorgovski's lectures are excellent, especially Week 4. I may be biased, as I knew much of the Planetary & Stellar material before, I didn't know much about galaxies, so week 4 was all new to me. The quizzes are well designed to test the student's understanding.

I'm giving the course 4, rather than 5, for two reasons: a lack of further reading, which many other courses provide; and the forums are almost completely dead. Generally I learn by discussing things with other students, with help from the instructors when needed. The course could work better, IMHO. This should not be interpreted as a criticism of Prof Djorgovski'slectures, which are worthy of Caltech!

Great course overall. Detailed coverage of the subject. Learnt a great deal of information. There is alot of content to cover and hence not much time is spent reinforcing concepts. Also, marks arent recorded in the free version of the course to allow you to track how youre progressing. Waiting to see if notification appears in completions. So far i havent seen a notification of course completion under completions or achievements. This may take some time to appear though.

great online course. it covers mostly all the astronomy topics in a deep-general way.

advanced math and physics knowledge is RECOMMENDED to understand several topics, otherwise, you'll need to research a lot.

engineering-level math and physics are REQUIRED to follow some exercises and examples.

Great course! Not only learned the concepts, also learned the math and how we know it, something that does not happen in school. The only problems is that some classes were mush harder than others so it was kinda like a rollercoaster of noledge.
