Pretty easy, overall.
This course is rather easy, especially if you're a STEM major. If you read the textbook and do the work, there is no reason that you wouldn't get an A or at least a B. The professor lets you use an 8.5" x 11" paper during exams on which you can write anything you want. Just make sure that you spend the time to prepare a paper for each exam.
I learned about each planet and other objects that orbit the solar system.

Advice for students:
For exams, write down the questions and answers in the online quizzes of the chapters covered in that particular exam. Also write down the conclusion of each chapter. For the online quizzes, the questions that are fill-in-the-blanks and those that are true-or-false are sometimes statements that can be found in the textbook. The fastest way to get the answer is to copy and paste the statement into Google and add the title of the textbook. You still need to buy the textbook though because this method leads to the Google Books link of the textbook, which only shows a few pages. You can also try doing a Ctrl + F on each page of your copy of the online textbook while taking a quiz.
