Spring 2022 - This was a great class! Definitely the kind of class that you get out of it what you put into it. Lectures are very engaging-- lots of participation opportunities (participation is extra credit btw) so if you're like me and you enjoy active learning rather than dry lectures, this is a good class. The professor really likes space and robots, which is great, because so do I! Many, if not most, lecture & hw problems have something to do with space, which is AMAZING. Also, there are no longer any MATLAB assignments! Just week-long HW's and quizzes-- HW tests your calculation skills, while quizzes test your ability to understand and explain concepts clearly, and derive equations. The class is definitely graded leniently, but it's also genuinely informative. (Btw, if you take this class, heads up that the professor uses a bar over a character to indicate a vector, rather than an arrow over that vector.) Overall, would definitely recommend this professor, especially if you're a space/robot nerd who likes engaging lectures.

He is nice and has a sense of humor, so that's a positive. It's really not worth it to attend his lectures. He goes on and on and it takes an hour for him to explain a single problem. 102 is a really difficult course because of the subject matter and it doesn't help when the professor can't explain the problems effectively. If you can, take 102 with another professor.

FOR 101/102 Klug is a good prof who takes the time during lecture to explain himself clearly and do good ex probs. He assigns way too much hw, but if you make the effort to go to office hrs, he'll work out entire probs with you. He really cares a lot about your understanding and isn't set out to fail anyone. He sometimes does extra credit and his exams are typically a lot like the hw/quizzes. You must submit work for EVERY hw prob to pass the class, though he post soluts you can copy later if you don't get it.

Spring 2024 - There are weekly homework assignments (~5 quick problems) and quizzes (one problem, 20 minutes, start of discussion). There's also one midterm. We're allowed half a page of notes on each quiz and midterm. I was able to get through most of the homework and quizzes just applying knowledge from physics 1A with ten minutes of google queries. I stopped going to the lectures after a while since I didn't find them particularly useful — still ended up with an A-. This class isn't too hard.

Fall 2020 - Her lectures were derivation heavy, so I ended up not watching them and just using the equations that she spent the lecture deriving on the homework/tests. The clicker questions aren't reason enough to watch the lecture if you're not paying attention to them, they are a very minor grade boost (less than half a percent). You are required to attend the first 20 minutes of discussion to take a weekly quiz, and those end up being a large part of your final grade, but they are pretty simple. You can leave the discussion after that, but discussion is probably a bit more useful since the TA will just be doing example problems. There is weekly homework that has pretty complex problems (much harder compared to tests/quizzes), and if you are able to figure those out (which is doable if you give it a few hours of thought, just start them early and try to work out the path to the answer, if you get stuck then wait a day and look again, don't look up the answers), then the quizzes and tests will be insanely easy compared to those. The midterm and final were just like a normal midterm and final, all in a Zoom call with the professor. They had the same level of difficulty as the quizzes (aka much easier than the homework).
