Ola's class was somewhat fairly structured. Her lectures were a little frazzled and sometimes it seemed like she had a hard time understanding the concepts herself. But it was curved very fairly. It is a lot of work outside of class since the homework is graded on correctness. Between the homework scores, two midterms and final, her class is fairly graded.

She is OK, compared to other math professors I had at UCLA. The class was not easy to me, but exams were doable, the average on each exam it was about 70%, and she gave us lots of study materials from previous years. Her lectures were often (but not always) helpful, she spends time both on examples and on proofs, she closely follows the textbook.

If you do homework, work through some old exams, and ask questions if you are lost (she is very helpful during her office hours and she will answer your questions when you approach her after the class), you will be fine.

Going in to Math 3C I had no idea what to expect as I was not really exposed to Combinatronics and Probabilities much in high school. The material covered is not unbearable and although I do recommend going to lecture it is definitely not required as long as you understand the sections covered and pretty much all the practice problems at the end of the sections. I personally never went to discussion due to a schedule conflict but I can tell you it is not impossible to get an A in the class even so. As for her midterms, majority of the problems are concepts that surface within the homework but she will also include a few questions that require a little more work/thinking but they are definitely within the scope of the class. Overall my experience with this professor was decent. As long as you put in the work for the class you will get the grade you deserve.

Hope this helps

Avoid her class at all costs. She makes the midterms a little too easy but only roughly 25% of the class will get some type of A, which is about 26 people in our class this quarter; so any small mistake WILL prove to be costly. Her lectures are useless, as she doesn't even deserve to be called a professor. She is hella nervous and doesn't even speak properly. And don't bother trying to ask her a question because she never knows the answer. Her lecture consists of copying things straight out of the book, so it's a waste of time even bothering to go.

Considering the variable difficulty of math professors, I would say that Kwiatkowska was not too bad. She was not at all a good teacher, but she had a generous curve and fairly easy exams. Our class was 10% HW, 25% per midterm, and 40% final exam. We only had 4-8 problems per section, and each assignment was graded out of 20 with 4 random problems chosen. The TAs do the problem in its entirety if you ask them to, so just ask for the difficult problems and you should be fine. The midterms were 6 problems each, with 100 total points. For all exams problems were fairly straightforward and simple, with maybe one or two harder problems. I took this class without taking 3A or 3B so I was lost every lecture, but I just read the book and went to the TA's office hours. They were all really good. My TA was John Lensmire, and he was really good, but sometimes brusque and condescending, so I went to Julian Gold's discussions and office hours (he was very patient and graded really generously).

All in all, Kwiatkowska's not the worst, but you have to be diligent and hope your lecture has at least one decent TA.

I took her for Math 3C and got an A.
The course only covered Chapter 12 in the Neuhauser book.
In the beginning of the course, the lectures are pretty helpful...probably because probability is completely different from Math 3B. It's completely new material. However, as the course gets harder, it becomes more difficult to understand what the heck she's talking about because she doesn't really explain things well. She might also be a little nervous because her English isn't that good. You'll find that she spells "lose" as "loose" and small things like that, which bother me personally but I guess we all have to get used to that.
But give her a break because she follows the textbook exactly, which is a godsend because all you have to do to get an A in the class is to read the textbook and understand it like 90%. Just know how to do the problems. If you do every problem in the book, you will be fine (there aren't that many problems).
Homework is kind of annoying because it's graded for accuracy, but if you have Chegg or some solutions manual then you should be fine. I did terrible on homework. The curve is pretty generous, like 25% of the class got A's. Out of 200 which is 50 people.

My TA was John Lensmire. Get him! He's really good. And Charlie was good as well. Pretty much all the TA's are good, so go to their OH instead because hers are pretty much useless.
