Her class is more disorganized than her Bruinwalk page.
Keep in mind this is a review for her Stats 101B class (Intro to Design and Analysis of Experiments) during Session C.
I'll emphasize she likes to ruin your weekend plans by assigning a test for the weekend. For this class, both the midterm and final were timed (2 hours) on Gradescope. However these exams didn't open until Friday 5 PM and it closed Sunday at 5 PM. So yes, my weekends were ruined because I had to worry about the exams.
I will also emphasize that she has no idea what she's doing. That's the story. Disorganized notes. Typos on the notes, homework, and homework solutions.. She makes mistakes during lecture.
I won't say it's a hard class but she's just not good at teaching.

I really have no idea why the evaluations for her 101B course are so bad. The class wasn't bad at all and she's a very nice person in general. She's very willing to help students and cares a lot about everyone's progress.
I guess some people might find the lectures useless, but for me, going to lecture was enough to get an A- with very little extra studying. Even when I missed 1 lecture, I found the notes to be pretty clear.
The grading is actually fairly generous, so there's no need to sweat about your grade too much. It's not exactly a massive curve, but the class isn't nearly hard enough to warrant one.
Overall, Mahtash is a pretty good teacher, and she has a motherly "aura" around her too (someone else mentioned something along these lines too). As for the class, Stats 101B isn't that hard, only slightly harder than 101A if anything. This can't even come close to the grueling 100ABC series.
Would definitely recommend taking this class with her! If you do at least decent, you'll get a good grade.

I have taken three classes with this professor. She genuinely cares about student learning. I think she does a good job teaching the theory behind statistics. Some of the other comments mention that she is not good at math but thats not what she's trying to teach. Anyone could use a calculator to add two numbers but not everyone could interpret logistic regression. It makes me sad that so many people are attacking her because she is such a good professor.

Do not take any her classes. She is worst and terrible professor at UCLA. She does not know how teach the class.specially, Her lecture note is trash and lecture is waste time.I can definately say that she is just middle or elementary school teacher. You have to study by yourself. In addtion, she is very lazy & do not prepare the class.

To take her for 101B is a big mistake. I don't know why she is so obsessed with group work. I mean group work is not a bad idea, but when you have so much to do, and you have slackers and semi-slackers in your group, your grade is pretty much done so!!! effing this professor...

Don't take her class. everything is useless & lecture is very confusion. you have to study yourself! lecture note also useless....... I hate her!
