She was always confused, not very helpful, could not understand her at times. Awful class

Cannot understand her with heavy accent and is quiet. Writes her notes on the board. She confuses not only the whole class, but also herself and redoes problems several times and sometimes even gives up. Does not answer students questions. Exams/quizzes and homework given every week its very hard. dont take this class!

The worst class I have ever taken in my life. I feel like she goes out of the way to make things more difficult and she is terrible at explaining things. the material covered is SO difficult and she takes a lot of time to explain it in a confusing way. She also is very inconsistent in when she says homework is due so i have missed homework before

She may be the worst teacher ever. She does not even address or acknowledge students before, during, or after class. She confuses the students along with herself. Her tests are so hard. What she teaches or attempts to teach is not even close to whats on the test. Her accent is almost impossible to get past. Very broken english. terrible do not take

Very hard class. Test are awful and the class is no fun. She confuses the class and herself and doesn't know much about business. I would very much recommend a different teacher.

Worst teacher ever. You can't understand what she is saying and she tries to make you do bad. She doesn't help you at all and everyone in the class just gets confused when she talks.

There are expectations to learn all TI-84 calculator info outside of class. Quizzes almost every Tuesday. Information is taught without refreshment on other concepts (expected to know). If you aren't refreshed on previous math concepts expect to pretty much take another math course by going to SRS because she is difficult to understand.

Absolutely horrible. Don't know how she got a job as a professor. I've had MANY poor math teachers but she is by far the worst. The material is already hard enough as it is, but on top of that she has a THICK accent. You can barely understand what she's saying half the time so get ready to comprehend close to nothing. You probably won't pass.

Jien took over multi-variable midway through the semester, in which I (along with all of our other classmates) was succeeding, learning, and enjoying the course thanks to the original professor. Jien is nice, but awful as a professor. Thick accent, cannot convey information, cannot help when confused, and brought the class avg crumbling down. Avoid

Not very approachable. Hard material. 4 tests makeup 5/8 of your grade. Hardest class i've taken thus far in college

Get ready to teach yourself everything on your own. When you ask a question, she gets really mad and tries to make you out to look or feel dumb. You will have a quiz every week, multiple exams, a couple hw assignments that will take you longer than the exams, and preclass quiz every class. She does not lecture, you teach yourself. (Applied Calc 1)

Hardest marker I have ever had. Ex $10 vs 10 dollars will mark you wrong for not writing it. 0.39999 vs .4 with no direction of how many decimal points to put will take marks off you. Does not teach, just reads her notes out loud. Does not even show you how to use the calc. Tells you to google it. My classmate is the only reason I passed & SRS

Assignments would take me days to finish because nothing taught related to the homework. If you asked questions she would get angry with you and barely answer what you asked. If you need more one-on-one time with a professor, do not take. Get ready to teach yourself.

Doesn't seem to care about students' success.

This professor is one of the worst I ever had. I was treated unfairly and when I tried to reason with her, she would stop responding to my emails. Basically any failure you have in this class is blamed on you and not her fault at all. Also terrible at transitioning to online classes and teaching, no effort in teaching students.

Avoid that professor. Disrespectful

Terrible Professor.

At the start of the COVID-19 pandemic, UC went fully online for it's classes. Professor Jien then posted a video stating that she would not be running online lectures--instead, weekly videos would be posted for calculus tutorials on YouTube from a random non-UC prof. Never saw her again for the rest of the semester. Horrible experience.

This class is hard but this professor made it even harder. I had this class during COVID and this professor had no lectures, just some semi-related YouTube videos to teach students. If you go to office hours to get help she Is very unclear and might accuse you of trying to get answers out of her. This course is passable, if you can teach yourself.

I had this professor during Covid and she made this time even more stressful. I spent about 15-20 hours a week on just this class. All that is provided to teach you are short YouTube videos from a random professor. When the students told her we are struggling and need more help we are told to read the textbook. She will ignore you if she disagrees!

Prof Jien didn't teach the class at all. We were taught through YouTube videos from another professor & often the quizzes didn't seem to be covered in the videos. Jien seemed to be bothered by students when we asked questions & was not helpful & it often seemed as if the student was being blamed for needing help. I didn't get what I paid for. AVOID

Rip off. Prof. Jien did not teach, lecture was YouTube videos from a former professor. Jien was not approachable at all. Any questions were met with rude, condescending, & short replies. Quiz material didn't match videos. Jien did not care about our success at all. After paying a lot of money to go to college I feel like I have been scammed here.

Never actually taught us, only used YouTube videos by some other math teacher. Did not offer much help when contacted with questions outside of class. Occasionally added 20 point quizzes with little to no notification which were due by the end of the day.

Avoid this Prof. She doesn't care about you. Her lectures are nothing like what is on the quizzes or homework. Never grades anything. Is no help when you have questions

WORST professor ever. Doesnt teach ANYTHING. Just sits behind her keyboard uploading other peoples videos and doesnt email back half the time.

If I were to say this is the worst professor/teach I have ever had, it would be an understatement. Our lectures were YouTube videos that she linked from another professor. We had weekly Post Video Quizzes, Homework's, and Exit quizzes all in which were mostly unrelated to the videos. She offered no help and often responded vert rudely to questions.

This is by far the worst professor at the University of Cincinnati, save yourself and pick a different math professor.

Not approachable at all. Calls math problems easy, as if to make people feel bad for not knowing them, even though she literally has no idea how hard a calc problem may be to those new to the subject. Condescending in that regard. Not approachable at all. Literally her entire class is only her doing math problems. Waste of an hour/day, DO NOT TAKE.

This professor is impossible. She doesnt upload anything ever on time and when she does 2 weeks late she is almost angry at you for calling her out. she constantly goes over the class time which can be difficult if you have classes back to back. she is also just inaccessible, she will never help you, you have to go to a TA. Worst professor ever.

Perhaps the worst professor I've ever had. Two main problems: 1) explains how to do math by going from one equation to the next without explaining why at each step. 2) Grades only half your test question by hand. The other half get no partial credit, even if only tiny calculation errors. Might be better in person vs. online.

This professor does not teach the class whatsoever. She posts videos of A DIFFERENT EDUCATOR with no credit to them and has it as our teaching material. Ridiculous way of testing us is making us learn a new subject while testing us on an old subject. 100% avoid this professor or this institution all together.

I've always done good in math, but she makes it the worst. She doesn't explain anything and makes rude remarks if you don't know what you're doing. Do whatever you can to switch professors. She doesn't even teach.

My whole life I have never been bad at math, however, I have to work for it. Personally I learn best through explanation. In this class, Professor Jien simply shows how to do a math problem with out any explanation of why or how. In her words "this should be easy," while most people in the class don't understand the topic, would not recommend her.

If i wanted to be taught by ta's id just teach myself because that is all that her class, you watch videos then go to her class and do a packet and hope that you can teach yourself calculus well enough.

I dropped this class in the middle of the semester because no matter what I did, I could not grasp the material because she DID NOT teach. She posted lectures of another professor online which you were expected to watch before class, then she gave you a worksheet on the material in class and did not teach whatsoever. Avoid at all costs.

Does not teach, instead posts videos of another instructor and counts that as the lecture. Worst teacher I have ever had. Avoid at all costs.

Unless you are completely insane, avoid at all costs. She might as well be speaking in riddles most of the time and almost never gives you a clear answer to a question. Without a doubt, she is the most bafflingly condescending teacher I have ever had.

Awful professor. Two quizzes a week and a 75 point test every Friday. Did not explain well. Made students feel stupid. DO NOT TAKE.

Avoid if you haven't taken Calculus at all. I can't imagine how difficult Dr. J would be for someone who wasn't introduced to the topics prior. I can tell she's knowledgeable about the topics, but barely gives students any feedback on work or on the lecture questions. Works through problems too fast. Random attendance quizzes, HW due every Monday.

Terrible. Does not teach the content tested on the exams. Avoid this professor if you can. Class is manageable but expect to teach yourself most of the topics covered. Has trouble communicating with students and is not empathetic whatsoever.

Do not take, taking this class will ruin your semester.

Horrible class, Professor J really does not care about her student.

This woman will make you miserable. I would not wish her class on anyone. Think of the worst class you have ever taken and then imagine taking it everyday. Professor Jien, not only extremely hard to understand and follow but also rude to anyone who asks questions or does not understand what she is saying.

Don't take this class if you want a social life. If you study, you might get a good grade. For the final exam, the study guide was nothing like a test. There was one video and two quizzes you had to complete each week and then five homework assignments due at the end of the week. She did give us chocolate on Halloween, though, and that was nice.

Horrible professor and class, avoid at all costs!

it was a flipped classroom, and she would teach things different then the videos did. soooo much work. 3 quizzes everyday one of which was attendance. did not understand how to teach students that didnt just get calculus. tests rarely matched study guides.

Avoid it if you want to actually pass. She uses daily videos then gives a paper everyday. Not to mention she does weekly bigger quizzes and then three quizzes a day for "practice" that literally does not help at all. If you try to ask her a question she'll just respond with "you should already know this" or "did you watch the videos?"!!!!!

She is terrible. You will not be passing if you take her class. She cannot be understood at all and explains nothing. Avoid at all costs and take your course online through a community college with an American professor.

I should have listened to the others on here bro. She's terrible. Made an exam on Halloween during one of my classes and the only other available time was 8-11pm that night. I ended up missing Halloween for some f*ckass exam. Picky on sig figs like others mentioned. Only class I've failed. 0/100 don't take her
