boring, doesn't teach at all, always tells you to read the book by yourself, no notes, learn nothing in class, but friendly

Horrible!!! Do not take this woman for any math class. Very hard to understand. Yeah she's friendly, but you can't pass a class just on being friendly. Grades unfairly.

Very unhelpful, i dont think should be teaching

true, she understands the material... but she's not a good teacher

Worst teacher at PCC! She seemed mad at the class when we asked questions and then never answered them. She may be friendly, but that does not make her a good teacher. Do not take her for Math! She should improve her English before she teaches again.

OM*G, BADEST TEACHER EVER, I WANT MY REFUND ON THAT CLASS, SHE f***ING CANT SPEAK ENGLISH GOOD, SHE CANT TEACH, SHE CANT TALK GOOD, SHE CANT EXPLAIN, SHE CANT DO ANYTHING GOOD FOR U. NEVER EVER TALK HER, U'LL REGRET IT.

She should be fired. I don't understand why they are allowing someone like this to teach a class. And I don't understand how it was possible for her to even get a degree. This woman should not be allowed to teach.

Makes a tough subject like math, even tougher. absolutely the worst.

She should be fired.

Is it a problem when the teacher says, "It's better to teach yourself than I teach you?"

They should require this teacher to complete a few ESL course before she even steps in front of a class. She requires a bunch of lame programming... that isn't even in the course description. She puts little tricky s**t on the tests. SHE SHOULD BE FIRED!

Probably the worst teacher ever at PCC. This hybrid course requires twice as much hw than in a traditional math class. Her lectures are more confusing than the book. Her tests are somewhat hard because her english sucks. The only good thing about her is that she will add anyone.

fire this stinker

HER ENGLISH IS NOT PERFECT! Give me a break...LOL Pathetic class and an even worse professor. Save yourself the time and money, and take someone else.

Although you come to class one per week which is good. You really have to read the book and try to learn it on your own. Don't depend on her to teach you. Her online homework is hard and does not make sense. Don't take this online class.

Two words: Cumulative Finals. Take the advice of other students - avoid at all costs. I wish I did =(.

I agree with the following comments. She is not very helpfull. Take this class only if your a self learner, or buddy up with someone in class! Trust me you wont pass this class on your own unless your very disciplined. She gives too much online and written H.W, so if u dont want a life go ahead take her class. But you've been warned

she's a really hard teacher i had to drop with a W :(

SHE WAS CONFUSING AND REALLY NOT HELPFULL

Like everyone on here says, she will really put you through hell. She does not except late work. She doesn't respond to emails, or if she does its not til 4 days later. She doesn't teach. Her practice tests are also nothing like the actual tests. I got A's and B's on the practice but only 1 A and few C's on actual test. Don't take.. seriously..

DO NOT TAKE THIS PROFESSOR!!! SHE IS NOT A GOOD MATH TEACHER!! SHE DOESN'T MAKE NO SENSE NOR DOES SHE CARE IF YOU UNDERSTAND WHAT SHE SAYS OR TEACHES.. I DO NOT RECOMMEND HER AT ALL!

WORST PROFESSOR IN HISTORY OF PCC! She lies to you, and then denies everything! Her grading is VERY unfair! She decided to SPLIT my grade with my husband. I got 31/40, so she gave me 16 and him 15. I (along with other people) have written complaints to the dean. I am thoroughly disappointed that she is still teaching! GET HER OUT OF THERE!

This professor is by far the worst professor at PCC. She cannot teach and she grades very hard. I would never suggest anyone to take this professor. She is also very unclear with her directions.

Run for your life

Don't do it

Leng is incredibly smart; however, Her curriculum was terrible. Online, if you missed one assignment you couldn't shrug it off, you weren't allowed to go forward, effectively failing that chapter. She needs to read these reviews and make changes, because this isn't learning. Do not take her class until she changes.

Ugh. One word to describe her teaching is uncomfortable. She is delusional to think everyone can learn the way she wants. The class is based off of her course manual, which is garbage, because it is as unclear as the lecture. The only way I manage to pass is by learning it myself through online math videos. I would not recommend taking her at all.

I had to drop her class even though I love math. She uses her course manual which has some mistakes. Unfortunately, when you talk to her about it, she doesn't give you a clear answer and says there is no mistake. Math should be straightforward but it's not with her. She also talks a big game how her class is better than others...

It is more of a science class then it is a math class. She should not be teaching math. Her lectures have nothing to do with the tests. need book and online access code.

DO NOT TAKE HER CLASS. She knows the material well, but her teaching style is abysmal. Halfway through the class, she got fed up with people asking questions and not keeping up with her and started taking it out on us by refusing to repeat things or answer certain questions. She's going for a tough approach but is too disorganized for it work.

does not teach at all, expects you to just understand, weird projects that waste a lot of time and don't have clear instructions. passed by cheating, took pics of failed tests and then did them again to pass.

don't take her class please. she's math ability is not good than student. Her teaching style is like Sumitomo who can't teaching well.

Don't take her class, she will give you a lot of homework and classwork, and she needs you to write summary on each classwork. I learned nothing in her class.

This professor is way too hard. She expects her students to be quick on math problems and the homework and classwork needs a lot of explaining

Don't take her class. Too much work and grades based on ALL she knows. Wants summaries for each classwork but basically wants an essay on every little thing with lots of detail. Wants us to justify everything but is terrible at explaining how to do it. Does not answer our questions directly so everyone is lost.. in the end, still doesn't answer it.

Professor Leng tries too hard to be unorthodox with her style of teaching. She abandons everything that you have learned in the past and expects you to do everything her way. However she does put in effort to teach you and if you really tried, you could get an A

This teacher explains math terribly which will leave you clueless all the time. Everyday you have to do classwork where you have to write a page long essay based on what you learned(nothing). The tests bring you down hard af. She also gives tons of homework which will take up your weekend. I took pre cal before and im still confused with her.

She was simply awful. This was quite frankly the worst class I've ever had at PCC. She wanted us to write essays explaining the classwork which she could not explain properly. The website is annoying to use. If you missed one assignment online then you couldn't continue to the next assignment and had to ask her to unlock.

This professor is just aweful. If you struggle with math please do not take her. I had to withdraw from her class if not I would have definitely failed by the way she was teaching. She is also very unclear on the assignments and gives lots of homework.

Stay away from this professor if you do not have any prior knowledge on calculus, her class is homework heavy and the essays do not make sense in a math class. Her teaching method is no concise and way too inefficient as compared to the traditional method of teaching. Do not take her class unless you have no choice. She uses her own notes too.

Mind as well KYS. She dictates how you write notes and wants you to forget what you learn before and do it her way. She doesn't understand that people learn differently. Anything is better.

This was one of the worst classes I have ever taken. Luckily I had taken Trigonometry before because this class would have been almost impossible if I hadn't. Say goodbye to your weekends because she assigns hours of work and makes you write out every step of your homework. I was barely able to get a B because of how terrible her teaching is.

Class was very confusing and she makes things harder than it needs to be. Better know your calculus if you want to take this class, lots of essay-writing and online tests almost every other week. If you are willing to endure all the homework , the class was an easy A if you do your work and write all the essay.

Don't take her. She gives tons of pointless essays every day. The exam is not that hard but she doesn't give enough time to finish. You must give an explanation following every answer you write. She seems to google a textbook and gives it to us and that book is bad.

Don't take her class. you must write many useless paper and learn nothing.

She assigned us a quiz that would supposedly take 4 minutes for her other students to do. We all didnt finish it until around 8-10 minutes. She shouldnt bring her expectations of other students from other class levels of math to lower or higher math classes.

DO NOT TAKE HER CLASS! If you care about your mental health and your grades, do yourself a favor and take literally anyone else. I've never been so stressed out nor have I ever had such a low grade EVER. She makes you write papers and it hits you so hard if you don't do them. I learned more calculus than algebra. Good luck if you have to take her.

Horrible professor. Makes you write out the lecture's material like an English class and gives you lots of busy work that you won't learn from. Rarely understand what you're asking and often go off tangent. Plus, she abandons Precalc in a Trigecalc class. My engineering friend is a better teacher than her, let that sink in.

Worse class I have ever taken. She is not organized at all. She thinks math is easy to learn and does not spend time answering questions. Focuses on herself more than the students?? Probably thinks her experience dictates how everyone's experience is like. I would not recommend this class to anyone who actually wants a professor that teaches. 0/10

If you care about your mental health, do not take this class. She gives tons of pointless homework & you learn nothing. Her homework is extremely difficult. Her tests are also unfair. The tests are even more difficult than the homework. Additionally, she DOES NOT and WILL NOT listen to her students. I have never had a professor as terrible as her.

Professor Leng is ruthless. Most of the assignments are not beneficial to the student and involve tremendous writing. She takes forever to grade assignments, does not follow her syllabus and will give you a bad grade without explaining why. I do not recommend you take her unless you are willing to undergo pain and suffering.

Take this class if you would like the most challenging and infuriating class of your life. She is not easy on students and is a very difficult grader. I am disappointed in how long it takes for her to grade assignments. My grade was good all year until it suddenly dropped as a result of not keeping up to date grades and I was unable to get it up.

Soooooo boring. I'm in algebra and she's already talking about what we're going to learn in CALCULUS. She makes us write 2 page journals once every week about what we learned in class, going in depth on strategies she taught us and it's so unnecessary. I feel like her classes would be 3x shorter if she just got to the point.

This is b my far my worst class I have ever taken. Her grading system is totally dumb and why is she even giving us assignments on weekends and not enough time to take the test. Shes a tough grader, it really take her awhile to grade. And she makes you right some stupid papers like shes an English teacher. Please dont take her class!!!!!!

Lots of work straight from book and not a lot of help in classes

DO NOT TAKE HER. I did not listen to the comments and I surfer for the entire semester. With a 4.0 GPA and in PCC for 2 years, I never hate a professor. SHE IS THE FIRST and WORST. It is an online class with prerecording lectures. She post 2 to 3 lectures per week but each lecture is over 3 HOURS. Such a waste of time and material makes no sense

do NOT take her! her as a human is amazing and sweet, but her class is a HUGE no! Please don't! I ignored these comments and took her, but my mental health was so bad because of her class. I was always stressed. the only reason i passed was because i showed her how bad i wanted too (while doing my work) if your bad at math as well don't take her

She says you will spend 15 hours a week working on this class, its more like 40 hours a week. So much homework and unnecessary work. Wants english papers and assignments in a math class. Take any other professor if you have a chance

Professor Leng understands what she's talking about but doesn't translate to teaching it well. She overcomplicates everything to a point where it doesn't make sense and also is a very inconsistent grader. She is also very hard to understand because it seems that English isn't her first language so everything she teaches is very unclear.

I dropped after the first class but I just came here to warn that this is NOT a regular Math 10 class. Do not take if you are not familiar with computer science or python because all homework is done through Jupiter notebook and you have to simultaneously teach yourself python while already taking a difficult class.

If you enjoy drowning in tidal waves of homework and getting entire problems wrong just because you didn't format your answer EXACTLY the way she wanted you to, you can't go wrong with Professor Leng. She also does a poor job explaining concepts then gets mad when asked to repeat herself. 0/5 avoid like the plague

Terrible class! The teacher is really nice but the workload is next level. No matter how hard I tried to catch up, I just couldn't. I wish I had read the reviews before I took her.

BEWARE: The statistics course is completely done through coding and Python. Extremely heavy workload, hours per week, and in the end, your grade will not reflect your effort. The professor is very tough, not understanding, and has been extremely unclear and inconsiderate during finals. Does not understand students work and have other classes.

Heavy Heavy workload, at least 7 assignments per week most of them taking hours to complete. The professor is a tough grader and can be unwilling to assist students. Your grade will not reflect the time and effort you put into the course.

Avoid taking MATH 010 with this professor. The workload surpasses typical college guidelines, with unclear teaching methods. Assignments are posted last-minute, demanding complex Python skills alongside linear algebra without adequate explanation. Choose another instructor for a better experience. she is disorganized and unprepared for lectures.

The amount of works this professor gives you is unbearable. She is also a tough grader. You have to answer all works in LaTeX and python. The amount of work is more than CS3A and math5C that im taking combined. Imagine got a 0/10 after spending 2 hours doing homework because it doesn't match her standard. Not even a single point for your effort.

Easily the worst professor I have had at PCC. Her lectures are mostly useless and all over the place. Her feedback on assignments is usually incomprehensible. She's a nice professor, but she is very difficult to understand. Class is very unorganized and the Canvas page is a mess. Coding makes class unnecessarily difficult.

Professor Leng is terrible. I mean extremely terrible, never take her class or you'll regret it. She can't even write a proper announcement, it's very hard to understand what she wants. It's Math 5B but she doesn't focus on the content, only cares about irrelevant side issues. Assignments are unreasonable and unnecessary. Never choose this name.

Professor Leng is the worst teacher I have ever had in my entire life. She is unclear about what she wants or about the requirements for assignments. She grades very harshly and demands that students present answers exactly the way she wants; otherwise, you will get a zero. She even uses AI to write announcements, and most of them are unclear.

I took Professor Leng's 5BH course and let's just say that it's not the best! I don't like how she sets unclear expectations and instructions for each assignment and announcement she posts. Instead of having to take exams, she makes us do projects and presentations! No Calculus concepts are explained thoroughly and only yaps about AI. AVOID!

She do the grading with biased personal reasons.
