So I am writing this review one day before my final. Guys she is horrible.
I have attended every lecture, done every homework, studied for every quiz and still dont feel confident.

She is mean, and unconsiderate. I might get an A but I wont pay a penny to take a class with her. Even if someone pays 1k I will proly not take her class. She does not deserve to teach man!

She is a b****

Stay away from this teacher. If you are to take her, prepare to be mind raped.

PROS:
- material in lectures she posts online are very organized – it was easy to find where any particular topic is

- uses Bruin Cast for the lectures, so you can always log on and hear the audio or watch the video of any past lecture in case you missed it or did not comprehend something the first time

- examples provided in the lectures were clear for the most part

- depending on your preference, the textbook can be helpful, but because though Sanchez never really referred to the textbook specifically within the lecture (just more listed as a reference at the beginning of the lectures so you know what section the lecture came from), the textbook is not vital to the class

- weekly homeworks made up 10% of the grade (one is dropped); all you have to do is attempt them, and you will get credit for them (this also depends on your preference if you actually want to know if you’re doing the problems correctly)

- NO FINAL; there are 3 small, relatively easy projects done for the class instead that were just 5% each

CONS:
- pace of the class at times was too fast, and even with re-watching the video streams and taking multiple hours to study the material, it was hard at times to stay caught up with the material in class as I was trying to comprehend the previous material

- 2 midterms at 30% each midterm toward the overall grade; there was only the 50 minutes to take each one, and like many of my fellow peers expressed, I felt that this was not enough time to sufficiently complete them. (A fact to back that up: Nobody got 100% on the first midterm – the high grade was somewhere in the low to mid 90% range.) This issue was brought up to the professor by some, including me, only to fall to deaf ears.

- lack of making the discussion section worthwhile; there was not much going on in those sections – it ended up being more of a place to ask questions rather than also having some additional examples available to help comprehend the material, something I felt would have been helpful at times (though maybe it was just me who feels this way)

- sometimes treated the lectures like it was high school all over again (such as being a stickler on how we labeled our assignments – it had to be all done a certain way or we lost points)

OTHER INFO ON THE CLASS:
- you still have to attend lecture because she has you do participation problems in class (10% in lecture; 5% in discussion)

- occasionally, there are problems where you have to use computer software (SOCR and R Studio, both of which are free) to complete them

- does base some problems on the midterms from homeworks and lectures one-to-one (maybe just changing a number or two)

I have never written a course evaluation before because I've seen it as a waste of time but for Professor Sanchez I will make an exception. DO NOT TAKE THIS PROFESSOR. By far the worst class I've ever had at any level. She cannot teach, makes simple subjects--like the normal and binomial models--extremely convoluted, and runs the class like a high school class. Attendance is mandatory, even though the lectures are worthless. The lecture notes are garbage, and her examples are anything but enlightening--usually they end with a probability of zero or one which, if you know anything about these models, should rarely happen. Don't make the mistake that I did thinking that if you know stats already you'll be fine in this class, she manages to somehow confuse you on what you already know.

She was a really horrible lecturer and could not stay on topic if her life depended on it.

HOWEVER. She gives you a course reader with all the material you need. So honestly, her lectures aren't really necessary considering they are directly from the course reader. So you can easily teach yourself everything you need to know.

When I took her class, she did random pop quizzes and attendance when she noticed the classes were getting low. They were partner quizzes so you got to work with someone if you wanted to and they were easy. Homework solutions could for the most part be googled or were done for you in section. If you know someone who previously took the class, get their old homeworks because they are EXACTLY the same.

As for the testing, I was so scared when I first went in becuase of all of the reviews on here talking about the lengthy tests and what not. Yea, they were long, but majority of them were MC...which wasn't bad. We got a calculator and a cheat sheet so that was helpful, but she does check the cheat sheet to make sure you didn't put any examples in it. After the first midterm, I learned she's a lazy test writer. She reuses old test questions, examples from the course reader, and questions from the practice exams in the back of the course ready (which I'm sure no one looked at).

She wasn't the best, but she definitely wasn't difficult. She was fair with no surprises and relatively nice.

I had a miserable quarter with her. She was a terrible teacher. She never fully answered any one's questions. By about half way through the quarter her T.A. realized what an idiot she was that she basically just gave us the answers to everything. She could not teach what so ever. She spent the entire class going over extremely simple examples, then assign homework that did not relate to it what so ever. Do whatever you can not to take her class.

Avoid her if you are not familiar with self-study

Here are some more details...
- can't write right: Omit assumptions when presenting definitions & theorems..
- she sometimes spends more than 5 minutes to just give people's homework back.. call every single people's name, then, fail to finish materials that she was about to finish that day.. then, let students study the remaining materials by themselves, finally, the remaining materials appear on exam.

Also, you need to go to lectures cause she usually gives us a pop-quiz at the end of the lecture.

I would not recommend taking Professor Sanchez. Although she is nice to most people, she came off very rude to me. Her lectures are not clear or effective and she does not add anything to the course to make it remotely interesting. The only pro is that she has a very generous grading policy (optional final) that makes taking the class worth it if you can stand her accent and boring lectures.
