由 MV 提供Mar 29, 2019
To try to compress the universe in only a few lessons is incredibly hard so we can only say this is an introductory course. I hope other courses are developed to explore this subject more deeply.
由 JH 提供Jul 15, 2017
Wonderful course! A brief introduction to cosmology but with plenty of material to cover. I recommend researching for papers additionally to the material, but you'll need more time than 4 weeks.
由 JI 提供Apr 27, 2019
I really enjoyed every lesson. It's an incredible and very complete course. Anyone who loves astronomy should do it. In addition, I was able to improve English, which is my second language.
由 AN 提供May 23, 2020
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.
常见问题
我什么时候能够访问课程视频和作业？
Access to lectures and assignments depends on your type of enrollment. If you take a course in audit mode, you will be able to see most course materials for free. To access graded assignments and to earn a Certificate, you will need to purchase the Certificate experience, during or after your audit. If you don't see the audit option:
- The course may not offer an audit option. 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.
我购买证书后会得到什么？
您购买证书后，将有权访问所有课程材料，包括评分作业。完成课程后，您的电子课程证书将添加到您的成就页中，您可以通过该页打印您的课程证书或将其添加到您的领英档案中。如果您只想阅读和查看课程内容，可以免费旁听课程。
退款政策是如何规定的？
您可在付款后两周内，或者在课程第一个班次开课后（对于已启动的课程）两周内，获得全额退款，以其中较晚者为准。获得课程证书后，您便无法再退款；即使您在两周的退款期内完成了课程，也是如此。请阅读我们完整的退款政策。
