Took this professor's course in Galaxies and Cosmology which was for 2nd year physics majors. I think this course is a more general course for non-physics-majors. Excellent course!

Thank you Prof. Djorgovski. For a school student like me, this course was an exposure to the fascinating world of astrophysics, which I plan to pursue while at college.

it was highly educational and it helped me to gain more knowledge in astronomy, with which i qualified as world finalist for the international astronomy and astrophysics competition!
When will I have access to the lectures and assignments?
To access the course materials, assignments and to earn a Certificate, you will need to purchase the Certificate experience when you enroll in a course. You can try a Free Trial instead, or apply for Financial Aid. The course may offer 'Full Course, No Certificate' instead. This option lets you see all course materials, submit required assessments, and get a final grade. This also means that you will not be able to purchase a Certificate experience.
What will I get if I purchase the Certificate?
When you purchase a Certificate you get access to all course materials, including graded assignments. Upon completing the course, your electronic Certificate will be added to your Accomplishments page - from there, you can print your Certificate or add it to your LinkedIn profile.
Is financial aid available?
Yes. In select learning programs, you can apply for financial aid or a scholarship if you can’t afford the enrollment fee. If fin aid or scholarship is available for your learning program selection, you’ll find a link to apply on the description page.
