After all the negative negative reviews written about her these years, I DO think she deserves a somehow OBJECTIVE and even POSITIVE one.

I took 100A and 130 with her, and right now I am a senior stats major student. Firstly I admit that some of her habits and regulations might make you feel uncomfortable or even a bit tired. But isn't it good to keep things organized and regulated? If she gives out clear instructions to follow, at least there will not be any unclearness or inconsistency in terms of homework assignments to turn in or exams, etc.

She is not really a bad or mean person,and I do think that she cares about her students. The reason why people think she is mean or cold is probably that she does not talk in a very passionate way I guess? I do think that she will see all the terrible reviews about her on this website, yet each time whenever she saw her students like me and my friends, she would give us a smile and a friendly greeting.

Can you guys imagine how she has made through these negative and malicious words against her and still be kind to students around?

In terms of her homework and exams, they are really pretty fair and doable. The class average is always not quite bad, and to be honest, even if her workload seems a bit much, she gives out grades very generously, as long as you do work hard and pay attention to her instructions.

So those of you who are still hesitating about whether or not to take her class because you are confused by these negative reviews, I do think Sanchez deserves a chance !

she is so unclear and mean. Worst professor ever in ucla. Her lectures are so useless and she never cares about students. Her office hour is literally a disaster. You have to wait like an hour, cuz she only lets one student in at a time and it's also useless office hour.

The material itself is very easy. Topics covered are just about the same as you would cover in STAT10 with the same level of detail. The professor was boring and rambled often so it made it difficult to follow. Examples in class were extremely easy but the homeworks and exams weren't as simple as the examples. The homework is excessive and is not very helpful. I'm going to avoid her if I ever see her taking another STAT course

Sanchez is not even close to what you'd call a decent professor, but I would highly recommend this class for an easy A without too much workload. The midterms are pretty easy (she didn't give us enough time on the second midterm, but she curved it so it was fine; otherwise, her midterms aren't curved). We really don't do R programming at all, whereas I heard you actually have time consuming R projects for 100A with other professors, so that's a plus with her. Although her teaching skills are generally lacking, the content is very useful and you can learn it effectively by watching lecture and doing the homework.

You really shouldn't have to go to her tiresome, boring, and mistake-riddled lectures since they're Bruincasted anyway, but keep in mind that she gives 5% extra credit for attendance. I couldn't attend most of her lectures due to a class conflict, but still managed to do fine without much extra credit.

Also, keep in mind that mistakes on her exams are not at all uncommon. If you're struggling with an MCQ that doesn't seem to have the right answer, or has more than one, just trust your instinct and choose one of the right answers, or what is closest to the answer, since her wildly incompetent self probably screwed up.

I really enjoyed this class. Sanchez's lectures were pretty good. She would always make these little jokes here and there so it made the lecture kinda interesting/kept me entertained me. But I'm guessing the person who submitted the evaluation below mine doesn't agree.
Anyway, her midterms were very fair, I would say that some (half?) of the question were from the homework, practice exams, or lectures. So you don't really need to study that much for them, and if you pay attention to lecture and keep up with the homework, you might be okay by not studying at all. The final though was hard though so you should study for that one.

Attendance was 5% of the final grade, so those are easy points.
Also in exams she's kinda strict about her rules of no talking and cellphones but that's not really a big deal. Well, I didn't think so but other people might disagree.

Most of these reviews for Sanchez are pretty humorous because they make it seem that the class is literally Hell and being in it is like the world's greatest injustice lol

The picture is pretty inaccurate; She's fatter and older now. As far as whether or not you should take 100A with her... she's really hard to avoid since the Stats department apparently won't let anyone else teach 100A.

She's really petty, makes unfunny jokes, doesn't have very good lectures or slides, and enforces attendance/participation on a class that has bruincasting as well as participation in discussion sections. She made left handed people sit in only left-handed desks for the midterm/final.

I spent most of my time in this class dicking around with my phone, and falling asleep. The result is that I had to spend about 2 hours studying for the midterm to get fully caught up (should tell you something about the pacing).

The class itself is pretty dumb. You don't really have to learn much, just write down the formulas and memorize your distributions.

Luckily for many people, this is the only stats class they have to take... I feel sorry for the rest of you.

That's right kiddies - your thousands of dollars in tuition help pay and endorse incompetent, useless, and indecent professors like Juana Sanchez! There were so many issues in this course that I can only imagine where to begin.

To begin, she did not properly answer any questions asked in class or office hours AND got defensive whenever you tried to assert that she is not answering the question you are asking. Well that helps. She is also rather rude when addressing anyone....I guess incompetency and indecency go hand in hand.

Oh btw, need some help with homework? Sure! Get in line outside her office - she only serves ONE PERSON AT A TIME EVEN IF MULTIPLE STUDENTS HAVE THE EXACT SAME QUESTION!! Want a regrade? Fill out some retarded form and give it to her - you may or may not get an answer. Any other query? Shoot her an email and set up an appointment. Oh wait...she does not even read emails. Pity.

Need an effective way to waste class time? Sanchez has got you covered. She will make random students go up to the black board and literally - word for word - write something that is already in the notes she hands out at the beginning of class. I'm rather proud - a friend of mine and I called her out for this ridiculous practice and refused to do it. It was glorious.

Homework? You had better follow her specifications or, as a nice evaluation below puts it, points off for every little minor fucking detail...like your assignment # not being in the correct place or a badly stapled paper. I also should mention that the typos are strong with this one. Difficulty wise it is not too bad.

Her exam administration is undoubtedly the best part though. 50 minute exam? More like 25 because she takes 15 minutes to take roll call (YES ROLL CALL !! WHICH PROFESSOR TAKES ROLL CALL DURING EXAM TIME?!) and will end the exam 10 minutes early with no warning. Final exam? 35 minutes to take roll call and ended 10 minutes early with no warning. Seating is also retarded. On the first exam we had to sit in a very tight formation in a classroom where a plethora of seats were available....just so that she could walk around the exam room and check your ID 4 times (YES 4 TIMES!!). Next exam and final was the usual one space in between. But wait....you could not use the desk next to you to balance your cheat sheets, test, scantron, calculator, pencils, eraser, exam, and a sheet she gave containing some of the typos on the exam. Can't use that desk or even the floor because it's "cheating". Yup it's going to be a balancing act on one desk and your knee ladies and gentlemen.

The exams themselves? I would recommend going through all practice exams and homeworks to memorize the answers to every multiple choice question. My friend and I managed to answer 11 out of 43 MC questions on the final in 45 seconds. Some of these questions required an immense amount of calculation that could have easily eaten away almost 10 minutes or more if there was an error in punching in numbers at any point. I also should mention that some questions have identical answer choices (A and C could literally be the exact same answer) while some questions may not even HAVE a correct answer (not mentioned on the error sheet she gave us). Our final, which was initially out of 51 points, got reduced to 47. How ironic....I stumbled across 4 questions that did not seem to have a correct answer while taking the exam myself...hmm....You can probably imagine how long students could waste on these questions trying to figure out why their answer is not there.

Overall, this professor intentionally and unintentionally through ridiculous policies and sheer incompetency makes this class more tedious than it needs to be. I have no idea why she still has a job. She does not deserve to teach at a reputable university...or at any university really. And that, kiddies, wraps up this eval.

Horrible Horrible experience! Worst professor ever. Plz, do yourself a favor. Avoid her! This guy is not supposed to teach in a university like ucla. She doesn't know her material very well and would let you do so many crazy useless things (a lot of formatting restrictions for homework and exams). This material for this stats 100a is not hard but she will try her best to make it hard.

WORST PROFESSOR EVER!!!!

I highly recommend you guys do not choose this teacher. She will only give you the final practice unless she get 100% of evaluations, thus our class do not get the final practice. Moreover, she is extremely old traditional! If you really need to choose this professor like I did, be prepared to be minded raped.
