The thing I love about Professor Sanchez is that she is the best at making concepts easy to understand:

(directly from 02/20/2015 lecture)

SANCHEZ: So, would you say that the people that are in the ‘college or higher’ group are independent of the people that are in the ‘high school or lower’ group? Do you think they are independent? Yes or no? Be, be courageous.

STUDENT: (shy) Yes.

SANCHEZ: Yes, yes. That’s it. Yeah. No, they are not. They are independent, right? No. They are not independent. Right? What did you say. Yes or no. No. You said yes they are independent, or yes they are not?

STUDENT: Independent.

SANCHEZ: Yes. They are independent. No. Yes. They are not independent, okay? They are not independent. I mean, sorry. Yes. They are independent.

Fuck this class.

This is the first C that I have ever received at UCLA. Honestly, I couldn't understand anything that she or the TAs were trying to teach us due to their heavy accents. As far as her tests go, for our second midterm, 60% of the class received Ds or lower, and she would not curve. On testing days, she spends the first ten minutes trying to arrange everyone in the right seats, tries to make sure that all students have different test colors, and does not let us start the exam until all of the late students are sitting in their appropriate seats. Lab discussions/normal discussions are a waste of time because she expects the TAs to cover a lot of information in a short amount of time, and its impossible. The TAs just end up writing a bunch of answers/codes on the board and expect you to get it (aka this class is all about teaching yourself).

From what I have heard of other Stats 10 teachers, I would avoid her at all costs. She was so confusing, hard to understand, not helpful, and just made the class as painful as possible. I took it during C sesh, so maybe it was due to crammed time, but the class was easily the worst I have taken at UCLA. The coding and exams are such a pain. If you are naturally good at statistics or already have basic knowledge, maybe this class will be fine. If not, I would HIGHLY recommend avoiding her.

CLASS: STAT 100A

Worst class I've taken. I had to use the slides from Christou because she was just awful. She has no idea how to give lectures and is extremely rude to students. Office hours are horrible and she is very condescending. During lecture she can also be very rude. She is all over the place when she lectures and she doesn't explain why equations work. The class itself isn't too difficult but she makes it unbearable, and the amount of homework she gives is unreasonable, this class was a lot of busy work.

Worst professor at UCLA. Unhelpful and not understanding. Counted me absent because I came 5 minutes late from the discussion section for that class right before. I explained this to her and even asked my TA to talk to her but he would not because he knew she would not listen. Horrible teacher

If you're like me, you read the (overwhelmingly) negative reviews for Professor Sanchez and thought "I'll be all right. I'm good at stats, I'm a solid student, it won't be a problem." In hindsight, I now realize that was the stupidest possible thing I could think. Sanchez is truly a horrible professor. I guarantee you will regret taking her for any and every stats class she teaches. DO NOT TAKE SANCHEZ. Even if that means you have to delay your plans by a quarter, do it. It's worth it.

Technically, this review is not for Stat 10, it's for Stat 20, but her teaching ability is equally bad across all classes (I have friends who have taken her for upper divs and for Stat 10 and wholeheartedly agree with me). To add some background about me, I took the equivalent of Stat 10 at a community college my senior year (got a 97%). I also got all As and Bs my first year at UCLA. I took Sanchez during the summer for 20, and oh. my. god. Sanchez is horrendous. She takes points off for absolutely no reason (trust me, read the other reviews). Her tests are confusing and unnecessarily difficult. Her notes are full of errors and her lectures are impossible to follow. I ended up dropping the class as I was struggling to even reach for a C-. It's not the material, it's 100% her.

Look, I realize taking a class in the summer is already going to cause it to be a lot more difficult. With that being said, the fact of the matter here is that whether or not Juana Sanchez is a brilliant researcher and wonderful head of the Statistics department, she is by far one of the most outrageous professors I have dealt with in more than 4 years at this university. This needs to be addressed.

To start she is so impossibly difficult to understand during her lectures that it has sparked more than one heated discussion among ALL of the students in the class about the difficulty of figuring out what she wants. An example: after the first lab was assigned, when we went to turn it in everyone, and I mean EVERYONE, had completed the lab in a completely different way because of the way she attempted to explain the directions. And not just because she has a thick accent and poor English, but she sidetracks herself during the lectures by ranting about her bad Bruinwalk reviews and berating students who are less than 5 minutes late, thereby completely forgetting her own lecture and backtracking on her own ideas.

She then assigns such a ludicrous amount of lab work that even our TA has blatantly complained to the students about the amount of work she inundates the class with, but even with his suggestion she refuses to change the workload. If all that isn't bad enough, she also took away a girls water during an exam simply because, and I quote:

"You have to suffer along with everybody else." I mean really? Sanchez isn't a bad professor, she is a completely unacceptable one.

She is horrible. I would wait another quarter if you need to take a stats class, or take 100A with Jaffe, then take this class. Both herself and the TAs are UNCLEAR and act like you are stupid when you don't understand a concept. Jaffe literally explained her entire class in a matter of 3 weeks and I understood everything. Avoid this class at all costs.

Very unclear. Her powerpoints and the textbook helped me self-study but there was no real teaching from her whatsoever. Spending 50 minutes in the classroom listening to her talk is a waste of your time.

There is an attendance sheet and she doesn't give enough time for exams because she talks about random distracting shit for the first 15 minutes.

There were midterm practice tests but she didn't provide a final practice test. Wanna know why? If 90% (I think it was 90%... it was something absurd) of the students didn't fill an evaluation for the course, she said she wouldn't make a practice test for the final. We didn't reach the number of evaluations she wanted so we didn't get one.

If you took stats in high school you'll be fine. If you've never touched stats, this won't be fun.

Lectures are pointless, she gets off topic and speeds through the slides before you have a chance to write anything down. She takes attendance so you kind of have to go through, but you can sign in and then leave and watch it on bruin cast if you want. If you can teach yourself, this isn't a bad class. It's pretty doable, everything is multiple choice though and she supplies practice exams for the midterms and final.
