Going to be blunt, and a little rude.
This professor should not be teaching, isn't mentally capable to teach anymore at this point in her life. Constant typos in important graded materials to the point where it looks like it was written by a senile person. I wish I didn't buy her textbook, as I didn't use it once the entire quarter. I cant remember if it was needed to access cognella (literally a ripped off version of ccle software). Doesn't care about the wellbeing of students at all, is not consistent on assignments. The way her assignments are valued changes on a weekly basis. If i had to guess, they moved professor sanchez to online asynchronous cause the students who had to suffer her in-person classes complained to much. Frankly I dont think she should be teaching at all, and it appears like the TAs do all the grading for her anyway. After taking this class, I still feel like I have learned nothing about stats. I dont know my final grade yet but im expecting anything from a B to an A-. I would have rather taken the class in person with a competent professor but they were not available to me. I wish I had waited to take Stats 100A instead. DO NOT TAKE THIS PROFESSOR. You are not going to be the top 1% of the class who gets an A. If you think you are, then you probably value your education, which in that case DO NOT TAKE THIS PROFESSOR since you will learn nothing. I am fuming that I spent money to "learn" in this class frankly, and she should use the money she has from scamming the university and their students to just retire.

If I was to blow my brains out, I think this class would be #5 on the list of things that made me blow my brains out.

It is incredibly frustrating the amount of work this class is. Notice how other sections fill up first. The midterm averages of other sections are significantly higher, have less material, less work, and less mental torture.

If I could equate this class to a piece of Greek mythology, I am Sisyphus and Professor Sanchez is the boulder.

I fucking hate it here.

Stats 100A is not supposed to be that hard a class. Content-wise it's not the worst, but Professor sanchez makes it way harder than it needs to be. She grades on an absolute scale where an A is 95+ and the range for B+ is 88-89 but B is 80-87. She overloads us with work, there is always lengthy homework, participation quizzes or random participation assignments due. She basically had 3 midterms, although she calls 2 of them "formal quizzes" and even though they're easy on content, it's IMPOSSIBLE to finish them comfortably in time. Lengthy computations make it impossible to score well in these exams, and a couple points here and there can get you down by 3 grades. She's also extremely intimidating, and unnecessarily condescending. I respect that she wanted us to be thorough with the material, but she treats us as if Stats 100A is our only, and hardest class, and gives too much work. I took this class thinking how hard can she make 100A, but trust me, avoid it if you can.

Professor Sanchez is infamous among the stats professor and I took her class knowing it was going to be a very rough experience. My expectation for her was low as yours will probably be, so surprisingly she did exceed my expectations. She is not as bad as other reviews describe as long as you follow her "rules".

Some things to note:
1) She takes attendance every single class. Sometimes twice every class! Sometimes it's on a sign in sheet, sometimes she roll calls, sometimes she tells you to turn in a in class exercise, sometimes she calls on random student's name to answer a question, sometimes it's all of the above.
2) There are a lot of in class participation points throughout the quarter based on the correctness of your answer and you will most likely not be given much time for those. However she is nice enough to let you drop the lowest two.
3) She assigns official homework once every two weeks. BUT, there is often smaller, shorter take home exercises that she will assign in class(and she may or may not post on CCLE about it). So pay attention in class!!
4) There are two quizzes in addition to one midterm and one final. She takes these assessments very seriously and will write you many many many bullet points on rules to follow. FOLLOW THEM! DO NOT OPEN YOUR BACKPACK WHEN YOU ARRIVE IN THE EXAMINATION ROOM. One time she was very annoyed at a particular student who looked through his backpack inside the classroom before she handed out the assessment. She yelled at him in front of the whole class and order him to sit at the very front.
5) Homework needs to be turned in within 10 minutes of starting class or else she will begin to deduct points. Try to turn it in BEFORE CLASS BEGINS, or else your P(getting yelled at ^ humiliated) = 1.

Despite my comments above, as long as you follow her rules and pay attention in class, have a decent TA, attend office hours, you will do just fine get at least a B+. She gets through a lot of material and you will feel like you've mastered a lot of material after her class. You learn a lot, more than other more "easy" stats 100a professors. And a bonus, she is quite entertaining, the way she talks, her sarcasm, and her occasional analogy of probability and life/death is quite accurate. She is very intimidating, but deep down, I believe Juana truly cares for her students.

Shout out to Lenny for being an amazing TA!

> Overall, Professor Sanchez has some strict rules but they were easy to get the hang of and the class structure made it really easy to learn the material without outside study. The class would be best for people who learn well during lectures and are detail-oriented.

> I understand why students would be frustrated with Professor Sanchez, she has a lot of very strict rules and is a bit rude to students who break them. But I found that if you just follow what she says as best as possible (it is hard sometimes) she's a fine professor. The class was easy and I feel like I retained a lot of the information. When she was rude in class it was often the student who started it by complaining about one of her rules, so just do your best to follow them without complaining and you'll be fine.

> She takes attendance randomly in lecture but discussion section attendance counts for extra credit so it's still easy to get 100% attendance missing a few lectures.

> In terms of the lectures, she gets turned around sometimes but overall the slides themselves are very clear and follow the book exactly. She does multiple-choice questions in class with color cards which some students found stressful but it doesn't count for anything so it's really fine. I actually found those questions super helpful because between those and the homework assignments I found I didn't have to study much to do well on the tests.

> For the tests she lets you have a full front and back cheat sheet with all the formulas so as long as you understood the homework (which is exactly like the book example problems) you'll do well on them. The hardest part is remembering formatting and details like writing down labels for the sets and events.

Take Sanchez If:
-You learn better with structure and someone constantly keeping you in check
-Dont mind going to class
-Learn by practicing
-Want to learn the basics of probability really well

Don't Take Sanchez If:
-You prefer to cram the night before tests
-Care more about getting a slightly better grade than learning Stats

Her class isn't hard, you are just going to have to do a lot of problems. The upside is the night before each test you will barely have to study because Sanchez already made you sure you've done each problem literally 10 times.

She's not as bad as people say! If you follow instructions and don't mess around, you'll be fine in this class.

I think a lot of the bad reviews just come from miscommunication/misunderstandings. There's definitely somewhat of a language/cultural gap between Prof Sanchez and her students, but if you treat her with respect, she will do the same. She is honestly very nice towards her students and cares about our success.

I emailed her multiple times and she was always willing to help and added words of encouragement and niceties in each of them that a lot of the reviewers below won't tell you about.

She is somewhat disorganized and goes extremely fast in lecture! Pay attention or get left behind (I often found myself in this situation multiple times). The homework is easy and can be finished in a couple hours at most, but her quizzes and tests often are too long to finish (in my opinion) without rushing super fast. Practice proofs! That's what separated me from getting a way better grade in this class.

The book isn't really necessary. You need it a few times in the class when her homework questions (maybe one or two per fifteen question assignment) ask you to go to the book for reference, but it's not worth 60-70 bucks, just go look at it rq in the Science and Engineering Library.

If anything, don't procrastinate taking your Stats 100a class because Sanchez is the only professor taking it (i almost did because of her reviews), just push through and you'll be fine.

Well, I don't wanna say she is a bad professor. However, she SHOULD NOT be your first choice. I took part of stats 100A with another professor last quarter and dropped it because something happened. It become get me feel regretful now.

She always let you do lots of meaningful work. For example, the class is MW but the deadline is Friday midnight. Although the grades is not based on correctness, you have to do everything perfect to get full credits. Then, you will have a quiz before Sunday midnight. Something like posting commonets is still part of your grades... FUCK

I promise, knowledge in stats100A is not that difficult. The only difficult thing is to finish all of your work. Normally, a stats class should only contains weekly homework, 1-2 midterms and a final. Some quizzes are still acceptable.

操,我不想说了。远离丫的!!!!!这里是地狱!这里是对你校园生活的折磨!!!我要不是因为着急毕业肯定drop掉。

This class sucks. Professor Sanchez is extremely unclear at explaining concepts, and it's not even like you can look at the textbook for a more clear / different explanation of concepts -- she wrote the textbook herself, complete with grammatical errors and non-insightful explanations. She has you complete these ridiculously long and tedious homeworks every week, making this class have one of the toughest workloads of my quarter even though it was by far the easiest material. A couple examples of non-related and non-helpful homeworks include one where you had to record an interview of you with another student about how probability was relevant in your major and another one where we had to submit a 2-page biographical paper on a historical mathematician in the field of probability. She hands out worksheets in lecture as opposed to discussion and has you talk to group members in the middle of lecture, so you can't even skip those even though they're borderline useless. The questions she asks are usually unclear or very poorly worded, and on top of that she can be eccentric to a fault - on our timed midterm, there was a question with a link to a YouTube video of a parody of 'Someone You Loved' by Lewis Capaldi with probability models, where the question was "which probability model was not mentioned in the video?" Something that would have maybe been funny to someone with a weird sense of humor and who wasn't in the middle of taking an exam. All in all, avoid taking this class with her as you will leave it with little useful knowledge except for how to get by in a class with an awful professor.

My grade isn't reflective of how heavy the workload for this class is. I am an individual who is super passionate about statistics so keep that in mind as you read this review.

- Her lectures were very intense because she had this whole ritual of pre-lecture readings with post-lecture slides to review for HWs, Quizzes, Exams.
- We had about 15 HWs through the quarter (so more than 1 per week) and they would take a while, especially if you were not engaged during lectures (which is entirely possible).
- Participation quizzes accounted for 25% of your grade...not bad right? They were a pain to answer because every lecture had a quiz you had to finish, a few had like 20 Qs (idk why she didn't just call those HWs).
- Midterm and Final were timed, which isn't a problem because frankly I prefer that, and her questions were fair and not impossible. Our distributions were how you'd expect them to be for a stats class with this large of a syllabus for 10 weeks.
- She did offer EC opportunities but those were in the form of more quizzes, which I was done with and did not attempt (to be exact I attempted 20% of ONE quiz out of 10).
- Her grading scale was that you needed a 95% for an A, so if you were not on top of your game from Day 1, you're likely going to heavily depend on a thick curve for one of the tests.

Finally,
Take this class if you have to, its not unbearable if you are passionate about stats and need it as a prereq for more computational upper-divs. But if this class is one of four, maybe five classes in the quarter and you just want to explore the field...hold it off for the next quarter.

Take Sanchez If:
-You learn better with structure and someone constantly keeping you in check
-Dont mind going to class
-Learn by practicing
-Want to learn the basics of probability really well

Don't Take Sanchez If:
-You prefer to cram the night before tests
-Care more about getting a slightly better grade than learning Stats

Her class isn't hard, you are just going to have to do a lot of problems. The upside is the night before each test you will barely have to study because Sanchez already made you sure you've done each problem literally 10 times.

She's not as bad as people say! If you follow instructions and don't mess around, you'll be fine in this class.

I think a lot of the bad reviews just come from miscommunication/misunderstandings. There's definitely somewhat of a language/cultural gap between Prof Sanchez and her students, but if you treat her with respect, she will do the same. She is honestly very nice towards her students and cares about our success.

I emailed her multiple times and she was always willing to help and added words of encouragement and niceties in each of them that a lot of the reviewers below won't tell you about.

She is somewhat disorganized and goes extremely fast in lecture! Pay attention or get left behind (I often found myself in this situation multiple times). The homework is easy and can be finished in a couple hours at most, but her quizzes and tests often are too long to finish (in my opinion) without rushing super fast. Practice proofs! That's what separated me from getting a way better grade in this class.

The book isn't really necessary. You need it a few times in the class when her homework questions (maybe one or two per fifteen question assignment) ask you to go to the book for reference, but it's not worth 60-70 bucks, just go look at it rq in the Science and Engineering Library.

If anything, don't procrastinate taking your Stats 100a class because Sanchez is the only professor taking it (i almost did because of her reviews), just push through and you'll be fine.

Well, I don't wanna say she is a bad professor. However, she SHOULD NOT be your first choice. I took part of stats 100A with another professor last quarter and dropped it because something happened. It become get me feel regretful now.

She always let you do lots of meaningful work. For example, the class is MW but the deadline is Friday midnight. Although the grades is not based on correctness, you have to do everything perfect to get full credits. Then, you will have a quiz before Sunday midnight. Something like posting commonets is still part of your grades... FUCK

I promise, knowledge in stats100A is not that difficult. The only difficult thing is to finish all of your work. Normally, a stats class should only contains weekly homework, 1-2 midterms and a final. Some quizzes are still acceptable.

操,我不想说了。远离丫的!!!!!这里是地狱!这里是对你校园生活的折磨!!!我要不是因为着急毕业肯定drop掉。

This class sucks. Professor Sanchez is extremely unclear at explaining concepts, and it's not even like you can look at the textbook for a more clear / different explanation of concepts -- she wrote the textbook herself, complete with grammatical errors and non-insightful explanations. She has you complete these ridiculously long and tedious homeworks every week, making this class have one of the toughest workloads of my quarter even though it was by far the easiest material. A couple examples of non-related and non-helpful homeworks include one where you had to record an interview of you with another student about how probability was relevant in your major and another one where we had to submit a 2-page biographical paper on a historical mathematician in the field of probability. She hands out worksheets in lecture as opposed to discussion and has you talk to group members in the middle of lecture, so you can't even skip those even though they're borderline useless. The questions she asks are usually unclear or very poorly worded, and on top of that she can be eccentric to a fault - on our timed midterm, there was a question with a link to a YouTube video of a parody of 'Someone You Loved' by Lewis Capaldi with probability models, where the question was "which probability model was not mentioned in the video?" Something that would have maybe been funny to someone with a weird sense of humor and who wasn't in the middle of taking an exam. All in all, avoid taking this class with her as you will leave it with little useful knowledge except for how to get by in a class with an awful professor.

My grade isn't reflective of how heavy the workload for this class is. I am an individual who is super passionate about statistics so keep that in mind as you read this review.

- Her lectures were very intense because she had this whole ritual of pre-lecture readings with post-lecture slides to review for HWs, Quizzes, Exams.
- We had about 15 HWs through the quarter (so more than 1 per week) and they would take a while, especially if you were not engaged during lectures (which is entirely possible).
- Participation quizzes accounted for 25% of your grade...not bad right? They were a pain to answer because every lecture had a quiz you had to finish, a few had like 20 Qs (idk why she didn't just call those HWs).
- Midterm and Final were timed, which isn't a problem because frankly I prefer that, and her questions were fair and not impossible. Our distributions were how you'd expect them to be for a stats class with this large of a syllabus for 10 weeks.
- She did offer EC opportunities but those were in the form of more quizzes, which I was done with and did not attempt (to be exact I attempted 20% of ONE quiz out of 10).
- Her grading scale was that you needed a 95% for an A, so if you were not on top of your game from Day 1, you're likely going to heavily depend on a thick curve for one of the tests.

Finally,
Take this class if you have to, its not unbearable if you are passionate about stats and need it as a prereq for more computational upper-divs. But if this class is one of four, maybe five classes in the quarter and you just want to explore the field...hold it off for the next quarter.
