No midterms, just quizzes throughout the quarter. They were take home with plenty of time to complete. The final was in the exact same format, just a little less time to complete and a couple more questions. As professor said, he doesn't want you to be concerned about the grade, just learning. The grading scheme follows that very well (homework is extra credit, extra credit problems on the quizzes). The book covers the content very well and is useful for the quizzes.

Really cool class, and Artur was a cool professor. He wasn't very responsive outside of class, but he was fine over Zoom.

Maybe the least amount of effort I've put into a class to get an A. Optional homework, tons of extra credit, and take-home week long tests.
