1) Lectures are nothing like the HW which is great because directions are also very vague! She often changed what she asked you to do on the hw half way through the week. Expect to spend HOURS on the homework just trying to figure out what you're even supposed to do, then get a bad grade on it because you didn't do it right (and yes, I asked for clarity and she just paraphrased the same instructions given earlier). Sometimes it seemed like she didn't even know what she was assigning/talking about.
2) Tests were a joke which makes me super confused about the hw difficulty and harshness on grading
3) Final is is a group project with a VERY open ended question & she urges you to interpret it as you want. I quote "There are no wrong ways to model if you provide the proper justifications" yet she docks points because she doesn't like your model. When our group met with her to go over what we had so far, she said everything was looking great, then dropped all of us a full letter grade because of the grade we ended up recieving.

Overall-- this class already sucks because of how all-over-the-place it feels in terms of content, but she makes it worse because directions are never consistent and grading is extremely harsh on content we were never taught in lecture. Sorry that you'll probably have to take it with her anyways because there are no other options! Enjoy!

Avoid when possible

Didn't enjoy taking this class at all. Professor Johnson was unclear in her lectures (took bits and pieces from the textbook, didn't explain anything clearly) and her grading on the quizzes/ homework assignments was very harsh.

Sometimes the homework assignments took upwards of 10-15 hours to complete. I will say that she wasn't very good at teaching Math 42 because she had no idea what she was even teaching to begin with. Overall, I wouldn't recommend taking this class with Prof. Johnson. If you don't have a choice, I'd suggest learning everything from the textbook (showing up to lectures isn't worth it).

I’m sorry for whoever has to take this class. Pro tip, wear protection before you let this class fuck you up.
