Reviews of professor Sarah Khankan

Rating: 4.0/5, difficulty: 2.0/5
Class used Aleks, completely async aside from in-person tests. There's a lot of weekly HW/quizzes/etc to get through but you can learn very well just by doing it. Easy to get 100s because of how Aleks works. She regularly posts lectures/tutorials/etc but I didn't look at a single one and still did well just by doing the homework. Khan Academy helps

The lectures are really straightforward, explained very well, and filled with examples. As long as you watch the lectures and do the practice problems, you'll get an A. 3 tests and 5 quizzes make up your grade, but they're all straightforward (no curve balls) and can easily be done as long as you follow along in the class.

She was great. Same lectures though.

If you made it through calc 2, you'll do perfectly fine in this class, just don't miss your weekly quizzes. She posts good online lectures with textbook practice problems, solutions, and explanations that are easy to learn from. Really doesn't require that much studying if you're keeping up with the lessons, and the practice she gives are the test.
