most difficult class to understand that I have taken. Went from an easy B in 106 to an F in 107 despite having an excelent TA (hurray for Mu-wan) merely due to the fact that this man explains nothing, he just does examples. class Avg on the first exam was a 56%. Best advice available...RUN!!!

Same problems as the student who took 107, Bo just does his own thing, regardless of the students needs. Test averages hover around 55-60%. His accent is also tough to understand.

Horrible to understand-- poor English, makes random comments to distract the class... I loved math until I took this class, because he was so unclear and provided no help!

Find the facebook group about him- it says it all...

Do not take this class with this professor. You basically have to teach yourself the class or must get outside help which is really time consuming!! He is NOT good at teaching material and sometimes just doesn't make sense because he is sometimes hard to understand because english is not his primary language...

AVOID THIS TEACHER! Bo is hard to understand. I got so caught up on him constantly saying 'formular', I missed out on what point he was trying to make. He skips around and doesn't clearly explain how to do things. When students asked for help, he told them he could help them - that they needed to go to the math resource center.

try to avoid him as much as possible

Just so you know, the class average for this class is an F everytime for most of the semester and by the end of the semester the average may slide up to a D or C- average if lucky. Needless to say, stay out of this class...get a different professor!

Not very helpful, makes tests completely different than the quizzes. Cannot understand a word the man says.

Class average = 60%. Get another professor if you would like to pass Math107.

Gives tests that are neigh impossible to complete given 3 hours, much less the 50 minutes he gives us. He doesn't teach so much as ramble, is never any help, and basically goes out of his way to mess up your grade. I've had to retake this class twice before, and now I'm probably going to have to again, and not because I don't understand it.

Bo Deng..Although it is evident that he knows a lot about math, he tries to teach it to you as if you already have your PhD. There is a strong language barrier and he can't speak in complete sentences. Also he goes off on random tangents and only teaches using proofs. I don't reccomend him unless you can teach yourself from the book.

if you can't teach yourself the material, choose another professor, because he doesn't do a very good job at teaching the material either.

Extreme boring class? not helpful?finish the course all by myself ? generous giving bonus though

run and hide

He is a horrible teacher. Try to get another teacher if possible. Math used to be my best and favorite subject but that feeling immediately expired with this man. His tests are impossible and averaged around 55-65%. I attended the other math lecture to get double help b/c he's awful. He needs to learn how to teach rather than tell information.

Terrible professor, avoid at all costs, proves everything and explains nothing, hard to understand, class average was an F

Deng is a horrible teacher. In lecture all he went over was proofs for the equations. He shows very few, if any examples of the homework in class. If you want to get anything out of the class make sure you go to the recitations.

Worst teacher I've had in 3 and a half years at UNL. Obviously doesn't want to teach and would rather be doing his research. Says that students can just teach themselves. Also difficult to understand. Listening to his lectures and continually mispronounced "formular" makes you want to scream. RUN!!

Easily the worst professor I've had and I've gone to UNO, Metro and UNL. Goes on random, pointless rants about nothing. Tests are near impossible. Not to mention he's impossible to understand. Take him if you want a death wish.

Run away. Far. Far away.

Can't understand him at all, just does proofs the entire lecture instead of doing examples. Our class relies entirely on our TA to even understand what we're learning. I've even already had calculus in high school and got an A nd he managed to confuse me.

This was the worst class I have taken yet at this University. Math is definitely not my strongest subject, but after taking trig last semester and receiving an A, I was really not expecting a 37 PERCENT in this class. The tests are absolutely ridiculous and his lectures do nothing pertaining to them. He is NOT a good teacher. $700 down the drain.

I literally cannot understand anything he says in class because he has such a strong foreign accent. am disappointed that the university would even hire someone like this to teach an essential Ace course. I took AP Calc in high school, and passed with an A (little bit of work) and this is the same course but I am struggling so hard to keep my B-.

I took calculus in high school and got an A, so I expected this to go well and be simply a review for me. I was WRONG. Math isn't my strong suit and I learn best on a step-by-step basis but all he does is go through irrelevant examples without any real explanation. If you have the chance to get a different professor, do it.

Do the homework and attend lectures, even if they confuse or bore you, and consider attending a second lecture with a different professor. After not doing well on the second test, I decided to go to a second lecture and realized that Deng does not teach everything that you need to know if you will continue taking higher math classes.

Not a very good professor. I learn by watching/doing examples, but he really didn't do a whole lot of examples and his examples weren't very good. He did a some things where he's like you won't need to know this but took 10min showing us.

Posts past exams that help, but don't bother asking him for help in his office hours. I have gone into his office hours 3 time max over the semester, just keeps stating "if you attended class" talking down to you without letting you clarify what you need assistance on. Weekly homework due, no quizzes, 2 midterms and 1 final. Do not take.

He's hard to understand and is unable to clearly explain things.

Most difficult teacher I have ever had. He is a nice guy, but doesn't understand that his students are failing because of his terrible teaching, not because of their own lack of effort. Our class was filled with high achieving honors student, and we averaged 50% and 60% on our tests, and he doesn't scale. Drop and switch to different section ASAP.

Worst teacher Ive ever had. Ive never failed a class till I had this guy. His accent is not understandable and he cant speak enough english to explain difficult concepts. He also lost one of my tests. Im really upset that I spent 4 grand on his bs. Pretty sure he was removed as an honors teacher

Probably the worst math professor I have ever had. His lectures are hard to follow and are long. Lectures are heavy on theory and really doesn't go over examples. Also he does not enter grades until the end of the semester so you really don't know how you are doing until the end of the semester.

If I could give him a 0 on the scale, I would. This is probably the worst math professor I've had so far. His lecture is so hard to follow, talks to himself in class and sometimes says jokes that is not related to the class whatsoever and laughs alone. We also have never left on time, he always uses an extra 2-3 min. to continue explaining nonsense

Bo is a bad professor who will teach math as if he will teach language class. Math needs paper and a pen, but Bo was reviewing exams by reading past homework. No idea how he became a professor!

not a good professor, can not explain everything clear, the exam is very tough, if you can, never choose his class.

So he cannot explain a concept clearly. The examples done are too easy there needs to be tough and easy examples. He will re-write the same thing about four times per lecture.

First off if you have Bo Deng as a professor I would change as quick as possible. He offers a class with a large amount of barriers in respect to a student's learning. Our class average before the final was a 59%. Test problems are not on par with lectures. We ended up complaining to the Math department, who made Bo raise our grades by 10%. Notcool

Lecture has no relevance with actual textbook or test material, does not help students in any way outside of class

Do not take a class with this professor. He struggles with English and struggles with computers. He also can be very disrespectful to his students. My class was partially online and he could not figure out how to show his screen with resolution good enough to be legible. He is intentionally pedantic and condescending when a student corrects him

Switches with the format of the exams, never productively answers questions, doesn't have any intention of finding out why the fail rate is so high with his classes, will confidently and gladly just move on to more unrelated content, and never address possible issues with his teaching style

Honestly one of the worst professors I have had period. You can still be successful in the class by utilizing the MRC, recitation, and teaching yourself, but the lectures are nearly useless.

As someone who came into this course from taking precalculus from high school, He teaches the class like it's a review. He never explains any of the concepts, All the problems he does do in lecture rarely have anything to do with the homework or the tests. He's a nice guy, but if you want to succeed in this course, choose a different professor/

Lecture for this class was brutal. Bo teaches like you've already learned the material and this class is simply a review. In lecture he starts off each section by going over the hardest possible problem in the section then expects you to know that section by heart. He's a nice guy, just not a good teacher. 106 is impossible to fail however.

The worst teacher I've ever had. I had taken pre-calc in high school and that is honestly the only reason I knew what was going on. He taught the class as if it was a review. Lots of rambling and used examples in class that did not apply to the homework or exams. Save yourself and your grade and do not take his class if you can.

Do not take with this professor

He will work through an entire problem in one 50 minute class. When working thru problems, often will get them wrong. Random questions not covered in class will show up on the exam. Learns the homework the same day it's due.

Do not take this class with Bo if you can. He is a professor who seems like he knows what he is doing but lacks a teaching ability. He speaks in a broken english and can be hard to understand. Tests are almost nothing like the review and he seems unforgiving on grading. Save your grade and switch professors. He seems like a good man yet not teacher

Avoid Bo Deng at all costs possible. His lectures make no sense and leave you in the dark for homework. Tests are completely different from anything we learned. He gets mad if the tech doesn't work and blames and gets mad at IT support to their face in the most disrespectful way possible.

If you have the choice, do not take a course with Professor Deng. I was forced to practically teach myself the course material, as lectures did not cover what was on homework or exams. On top of that, two of four exams were hardly like the review material given. He seems like a very nice man, but he is incompetent when it comes to teaching.

I'm not even sure this guy knows how to teach a class. Attending lectures is useless because you'll walk out knowing less than you walked in with. Tests are nothing like the homework. Save yourself the stress and pain by finding a different professor.

Bad teacher

Do not take a class with Bo Deng. If you didn't take Calc in high school then you are cooked. Save yourself the tears and find a different professor because you could learn more from a brick wall than you could from him. If I had the choice to jump into shark infested waters or to take this class again, I would jump into the shark infested waters.

I felt discriminated against by him. In Exam 1, I answered a confusing question as "does not exist" and asked him for clarification, but he refused to help and was disrespectful. Later, he assisted a white student with the same question and fixed it right away, making me feel uncomfortable and unfairly treated.

Bo Deng is not a good lecturer he is very confusing on how he sets up equations and doesn't explain how he got places in the equations. He isn't very available to students. Recitation is where I have learned almost everything just to go into lecture and become lost once again.

Good guy, bad teacher

Very Difficult Class

One of the worst teachers I've had by far. Doesn't teach the theory and focuses purely on examples. Teaches the class as if it's a review, not people learning it for the first time. The only reason I managed to pass was because of my reciation TA. Would often understand the material, then go to lecture and walk out even more confused.

Felt I was taught better in the MRC then in his classroom.

As another commenter said I would avoid this class at all costs it really is learning from a brick wall He takes his syllabus directly from a different professor without changing a thing I've basically self taught myself all of calc 3 I would rather drop my degree before taking this class ever again

nice guy, bad professor. Avoid at all costs

Only class I'm going to fail my whole degree. Professor Deng knows his stuff, but it really is like talking to a brick wall. He simply can't teach from a students perspective. A review said that they walked out of the lecture more confused than before, and I 100% agree with that. He will leave you stranded if you can't keep up with his level. Avoid

Avoid him at all costs. You could 100% understand the homework, textbook, lectures (unlikely), and recitation, but be completely lost on the exams. They do not match up with anything you have learned at all. I do not know where he pulls them out of. Lectures are terrible and a waste of time, but you get points for going. DO NOT TAKE

He's a good person, but he makes the course x10 harder with his teaching.

I'm strong in math and have tutored calculus, but Bo Deng is the worst professor I've had at UNL. He's smart but a poor teacher— his tests are inconsistent, with material not covered. No matter how much you study, test will not reflect that. I learned more from YouTube and my TA than his class. Avoid him at all cost! Do not spend a dime on him.

Bo Deng was my 1st class at UNL. i thought i was going to learn things in lecture. He has completely destroyed my perception of higher education with the lack of learning in his lectures. Do not waste your time with his lectures. Learn calculus based off the people in the MRC & GPT with the homeworks. God help you.

Dr. Deng is a great guy and is funny but cannot teach for the life of him. His teaching strategy focuses on very niche theory and concepts and examples do not prepare you for the test. He does give plenty of review material though. For reference, this is my first math class in my life without an A.

Worst lectures I have ever sat through. My resi TA single-handedly saved me. Attendance is graded for both lectures and resi, tests are not curved. The course is not hard enough that you can not get a good grade even with Bo as your prof, but if you can take any other professor, take them instead.

Bo is a great dude and he is funny, but he is too smart to teach. I understood barely anything he said because he over explains every topic and makes it more complicated than it is.

Very difficult to understand and keep up with and doesn't respond to emails from my experience. Go with another teacher please
