absolutely the worst professor ever in my experience at UCLA. There are way harder classes but you can always count on Sanchez to disgust you throughout the semester. The first thing she asks you to do is to buy a 70 dollar textbook that she wrote, which did not come into use once throughout the entire class. THERE ARE PAGES OF INFO ON HOW TO BUY THE BOOK ON THE COURSE WEBSITE BUT NOTHING ON HOW TO ACTUALLY USE IT. She also punishes you for every single trivial detail you did wrong, whereas she makes typos in almost every homework and ppt, making it confusing what she wants from you in the first place. In addition, her teaching is absolutely horrible: she just reads the most basic stuff in the ppt and forces you to learn the actual hard contents by yourself by making them homework or quizzes. There is actually one time where SHE MADE US SELF STUDY 1 WEEK'S MATERIAL THAT SHE DIDN'T TEACH TO DO HER PARTICIPATION QUIZ. If you try to aim for a straight A( which btw she raised to 95 instead of 93), you'll most likely end up feeling you spent more time feeding her ego than actaully mastering the content of the class. What an insult to the teaching profession as well as the time and money students spend to get their collage education. It's amazing that she is still allowed to teach here. I've had my share of bad professors, but Sanchez just took it to another level.

I was very scared to take 100A with Sanchez because everyone hates her but she's turned out to be one of the best professors I've had in my time at UCLA. Don't take her class if you like to procrastinate or if you're gonna whine about her strict rules. She's strict but never unreasonable, and if you think she's making up rules it's probably because you don't pay attention. Every rule she makes she makes sure to clarify days in advance. If I were her I would be very irritated all the time with my student because people love to try to show her up during class.
Overall, her class is fantastic because it's structured and ensures that if you complete assignments you will actually learn the material and not have to cram. I really recommend her if you don't trust yourself to study diligently because if you want to pass her class you really need to follow along. Would definitely take another class with her. If you like organized professors, take a class with Sanchez. It might not have been an easy A but at least I learned...which is something I couldn't say for most of the classes I've taken at UCLA.

I'm honestly shocked I got a C+ in this class. Despite her inability to teach anything I was able to teach myself with the help of the book and I got mostly 100% on every quiz and homework she threw at me. I understood all the material well. The problem was she doesn't give enough time for the tests at all! Unless you go to a test bank and memorize her previous questions or look up questions on Chegg, there is no way you can finish in time, especially on a crappy scientific calculator that I had to buy since she doesn't allow graphing calculators. Do yourself a favor and avoid this class. It's such a joke.

I am a senior math major. I am confident with my skills in calculating but her class gives me a spectrum of confusion. Regardless of how well I understand the materials in this course, I always lose points to either having not enough time or having trouble decoding her grammatical errors in the problems. She is simply an unfair person; and to me, she doesn’t know how much of something is considered to be enough and fair. She lets you bring a 4-page cheatsheet to your final but don’t be so happy about that since she doesn’t let you have any other things rather than just raw definitions. Honestly, I just want to say that most of the comments here are very precise about her. If you are a math major, don’t ever take this course even though it is indeed easier than 170a because you will get pissed off because of this professor and eventually lose your interest in attending her lectures that will lead to losing your points.

As other commenters have said, there is ton of work in this class. Every week, you have a new homework assignment (~10 questions) and a CCLE participation quiz (30-40 multiple choice questions). I never had to do so much required work outside of class in my life. Unfortunately, she doesn't even go over some of the material in the homework and CCLE quizes, so you're stuck having to email/speak to TA's for help.

For her quizes and exams, she gives you no time to do them. Each quiz is 25 minutes long for ~6 questions. You must show full work (you do get partial credit), and you have 50 minutes for a multiple choice midterm (no partial credit). You do get a cheatsheet for the midterm/final, but the professor limits what can be put on those sheets. You don't have time derive anything, and because the midterm (haven't taken the final yet) is so short and multiple choice, you better have memorized every formula that you were not allowed to put on your cheatsheet.

هذا صحيح ، أيها الأطفال: إن آلاف الدولارات التي يحصلون عليها من التعليم تساعد في دفع وتأييد الأساتذة غير الأكفاء ، غير المجديين وغير المحتشرين مثل جوانا سانشيز. كان هناك الكثير من المشاكل في هذه الدورة التي لا أستطيع إلا أن أتخيل من أين تبدأ.

بادئ ذي بدء ، لم تجب بشكل صحيح الأسئلة التي طرحت في الفصل الدراسي أو ساعات العمل وأصبحت دفاعية في كل مرة حاولت تأكيد أنها لا ترد على السؤال الذي تطرحه. حسنا ، هذا يساعد. إنه أيضاً وقح جداً عند مخاطبة شخص ما ... أعتقد أن عدم الكفاءة والفساد يسيران جنباً إلى جنب.

أوه بالمناسبة ، هل تحتاج إلى مساعدة في الواجبات المنزلية؟ بالطبع بكل تأكيد! الحصول على الإنترنت خارج مكتبك: إنها تخدم شخص واحد فقط في أي وقت إذا كان الطلاب المتعددين لديهم نفس السؤال الدقيق! هل تريد خريج؟ املأ نموذجًا مؤجلًا وقم بإدخاله ، فقد تحصل أو لا تحصل على إجابة. أي أسئلة أخرى؟ اطلاق النار على البريد الإلكتروني وتحديد موعد. أوه ، انتظر ... حتى أنها لا تقرأ رسائل البريد الإلكتروني. شفقة.

هل تحتاج إلى وسيلة فعالة لإضاعة وقتك في الفصل؟ سانشيز لقد قمت بتغطية. سوف يجعل الطلاب العشوائيين يذهبون إلى اللوحة السوداء ، و حرفيا كلمة بكلمة ، يكتبون شيئا في الملاحظات التي يقدمها في بداية الفصل. أنا فخور جداً ، صديق لي ، وقد اتصلت بها من أجل هذه الممارسة السخيفة ورفضت القيام بذلك. كان مجيدا

واجب منزلي؟ من الأفضل أن تتبع مواصفاتك أو ، كما تظهر برامج تقييم جيدة ، تشير إلى كل تفاصيل ملحوظة قليلاً ... كيف أن الواجب المنزلي الخاص بك # ليس في المكان المناسب أو الورق الذي يتم تدبيسه بشكل سيئ. يجب أن أذكر أيضا أن الأخطاء المطبعية قوية مع هذا. الصعوبة الحكيمة ليست سيئة للغاية.

إدارة الامتحان الخاص بك هو ، دون شك ، الجزء الأفضل رغم ذلك. اختبار 50 دقيقة؟ أكثر مثل 25 لأنه يأخذ 15 دقيقة للذهاب من خلال القائمة (YES ROLL CALL! ماذا تفعل ROLL CALL خلال الامتحان؟) وانه سينهي الامتحان 10 دقائق في وقت مبكر دون إخطار. إمتحان نهائي؟ 35 دقيقة لتمرير القائمة والانتهاء من 10 دقائق قبل دون سابق إنذار. الجلوس أيضا تأخر. في الامتحان الأول كان علينا أن نجلس في تشكيل ضيق للغاية في فصل دراسي حيث توجد الكثير من المقاعد ... لذلك يمكنها أن تتجول في غرفة الفحص وتحقق من هويتها 4 مرات (نعم 4 مرات!). الامتحان التالي والنهائي كان الفضاء المعتاد في الوسط. ولكن انتظر ... لا يمكنك استخدام المكتب إلى جانبك لموازنة أوراقك المخادعة والاختبارات و scantron والآلة الحاسبة وأقلام الرصاص والممحاة والاختبار والورقة التي قدمتها مع بعض الأخطاء المطبعية في الامتحان. لا أستطيع استخدام هذا المكتب أو حتى الطابق لأنه "الغش". نعم ، سيكون ذلك بمثابة توازن في المكتب وعلى ركبتيك ، أيها السيدات والسادة.

الامتحانات نفسها؟ أوصي بتمرير جميع اختبارات الممارسة والمهمة لحفظ الإجابات لكل سؤال متعدد الخيارات. تمكنت صديقي وأنا من الإجابة على 11 سؤالاً من أسئلة MC حول المباراة النهائية في 45 ثانية. تتطلب بعض هذه الأسئلة كمية هائلة من الحسابات التي يمكن استهلاكها بسهولة لمدة 10 دقائق أو أكثر إذا كان هناك خطأ في طلب الأرقام في أي وقت. يجب أن أذكر أيضًا أن بعض الأسئلة لها خيارات إجابة متطابقة (يمكن أن يكون A و C حرفياً نفس الإجابة) ، في حين قد لا تحتوي بعض الأسئلة على إجابة صحيحة (لم يرد ذكرها في ورقة الخطأ التي قدمتها لنا). تم اختزال نسختنا النهائية ، التي كانت في البداية 51 نقطة ، إلى 47. كم هو مثير للسخرية ... تعثرت على 4 أسئلة لا يبدو أن لديها إجابة صحيحة عند أخذ الاختبار بنفسي ... هم ربما ... يمكنك تخيل كيف الكثير من الوقت قد يخسر الطلاب مع هذه الأسئلة في محاولة لمعرفة السبب في عدم وجود إجابة.

بشكل عام ، هذا المعلم ، عن قصد وعن غير قصد ، من خلال سياسات سخيفة وعدم كفاءة مطلقة يجعل هذا الطبق أكثر مملة مما ينبغي أن يكون. ليس لدي أي فكرة عن سبب امتلاكها وظيفة. إنها لا تستحق أن تدرس في جامعة مشهورة ... أو في أي جامعة حقاً. وهذا ، الأطفال ، ينطوي على هذا التقييم.

This professor is terrible in teaching, despite her dedication to classes her method of teaching and her requirements for you are just ridiculous. You learn nothing from the lecture, like literally nothing, words cannot describe how awful her lecture could be. Tons of homework to do, and no curve at all, only overall >95% is an A. Avoid her if you can, I wouldnt recomand her regardless of your interest about stats. If you like stats, her terrible teaching will make you suffer a lot, if you dont care and just want an easy A, her tedious requirements will drive you crazy and you wont probably get an ideal grade. I like stats a lot, and most of the stats class i take in ucla have been nice experience for me, but her class made me so miserable.

Oh my god. guys, Sanchez Juana is absolutely HORRIBLE. she is a nightmare. we all had to drop her class because she is just sucks.

she doesn't give any other second chance to students, never cares about her students, strong accent and long homework.

I am not a bad student, but I become a stressful person after taking her class. stay away from her. wait later to take it with another teacher.

As a third-year undergraduate student, I have had to sit through countless boring lectures, suffered through several stressful nights because of a class and I have never once taken the two minutes out of my life to write a bad review on a professor. Juana Sanchez however, is something else. She is such a bad professor that I had to take time out of my busy schedule to warn my fellow bruins about her reign of terror. Juana Sanchez is such a bad professor that I considered switching to physics. That's right, physics. She, a stats professor, made physics seem easier. I never failed any exams, she just failed to educate me. Gene Daddy Block would have been a better stats professor and he's was a Biology major. That's right, a tree hugging, hippy would be a better professor. I know all of this sounds harsh, but there's a point here. She's shit. So do your G.P.A. and future self a favor and avoid her class.

Sanchez is by no means a spectacular teacher but she's also not the complete nightmare that some are making her out to be. First, the lectures aren't very engaging or anything. It mostly consists of her going through the slides, which you will also be given a printout of. However, there are occasionally problems she asks you to do in class that will be graded so you can't always take the printouts and skip lectures. Most of the slides aren't useful - you just have to pick out the few that have important equations/formulas and focus on those.
There are weekly quizzes. They're not too hard if you go to discussion. The TA gives you a worksheet, gives you some time to work on it, then goes over the answers. They're generally a pretty good measure of what questions on the quizzes are like so I recommend going to pick up the worksheet at least.
One issue is that Sanchez isn't very clear about due dates and what work she wants done when. You'll often have to check CCLE to be sure of any due dates. Between practice homework, practice quizzes and other assignments it's a tedious amount of work, but not very hard to do.
The midterm is pretty easy. The final is harder and has some proofs involved. Overall the class isn't an easy A but probably won't require as much work as other classes.
