Quarter: Fall 2023
Grade: NR

1. No practice exams, may easily bomb if you take it easy
2. Need careful review after class, as TAs do little help
3. Requires strong self-study ability to do well in the class (this class is not as easy as it supposed to be)

Quarter: Fall 2025
Grade: A+

I had Johnson for my first quarter at UCLA. Maybe she made it easier due to earlier classes, but I found this to be a very reasonable math class. This was also thanks to my GOAT TA, Kye (shoutout to him). Long story short: do your homework as soon as it’s published, know how to solve all the problems, and you’ll be fine. She rarely tests the most difficult concepts—if anything, I only lost points on the easiest stuff (like forgetting to label “lim n → ∞”). She also gives partial credit.

Honestly, her notes are very clear and cover exactly what you need for the class, and you can always cross-reference with your TA and Khan Academy. There’s nothing scary about this class—just study consistently, attend office hours or go to the math center at least once a week, and you should be able to pull out an A 🙂. Also, make friends in this class—it really helps for studying.

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

Grade: A

Prof Johnson is a good lecturer. She does examples in class which are helpful. Exams are more difficult than homework, but partial credit is given. Uses 2 different grading schemes and used which ever scheme gives you the highest score.
