  • Kristina Šekrst completed this course and found the course difficulty to be easy.

    This course gives a much broader overview than it seems, it's an introduction into physics in general, into our Solar system, and into topics like relativity or quantum mechanics. It's more of an introduction to astronomy, rather than introduction to exoplanetary astronomy. The lectures are nice, with interesting videos (loved the Dyson one!), too bad Princeton does not offer any certificates whatsoever, and that this course is an on-demand one. Peer-reviewed assignments would function better if it were a live course, this way this nice course seems a bit lonely.
  • Sampath Kumar

    Sampath Kumar completed this course, spending 5 hours a week on it and found the course difficulty to be medium.

    I did not completre this course and hence repeating it. The course is pretty detailed and requires concentration. The length is one inhibiting factor for those interested to learn about exoplanets.
