too many students dropped this class. he was very confusing and didn't answer your questions or teach you anything about the material. he had a bad attitude about teaching and was very unprofessional. don't take his class!!! or you will be doomed in math!

i've had 2 years of calc in high school, and i'm still struggling in here. i don't think it's a hard class but he is very unprofessional and not enthusiastic. take the class, but with a different teacher.

Just don't take him...you'll regret it.

This class was EXTREMELY hard...I hated calc and was forced to drop it :(

Not only is he a terrible teacher in the sense that he can't teach for crap, but he is a jerk on top of it, and likes to make his students feel dumb and inferior. There is a reason why he only has about 5 kids in his class every semester.

Lang is the worst math teacher I have ever had. If I wanted to teach myself math I would have saved myself the 2 grand I paid to take his class. Claims its your own fault if you don't learn anything, you should have just tried harder. I say...

I say if he wants anyone to learn he should get off his ass and teach. If you take his class, you just better hope the rest of your classmates are geniuses cuz the students are responsible for teaching each other. Take my advice and DROP THIS CLASS

This is the worst professor that I have ever had. He does not teach you and I dont know how you are expected to learn when you are told to read the book and class is for if we have questions. This is college I am not paying all this money to teach myself.

He sucked. Didn't teach anything at all ever, need I say anymore??

Dont take this professor for 223! He does not teach you anything, it is just read the book and ask questions. That is nice, if he finishes the questions without the "o well you can do it from here". Taught sections in like 5 minutes and then told you to read the book. Also needs to wear longer shorts.

Yeah so even though this class was basic math it was not math. It was logic and I had so much trouble and Dr. Lang couldn't take like 5 minutes after class to explain something to me. The quizzes are stupid and tests are stupid, they don't cover the material. He tells you to figure stuff out yourself. Don't take him.

Worst teacher ever. I love math and have a fairly strong background in it but I didn't learn a thing. I had to teach myself. Tests are hard but have big curves but still impossible to get an A. webassigns twice a week and quizes every friday.

The dude is insane. I'm very good at math, and this guy had me completly lost the whole time. He assigns homework problems from the book, but none of them are on the test. He makes the tests impossible, and then curves them. its impossible to get anything above a C in that class. AVOID AT ALL COSTS!

he is absolutely terrible! DO NOT TAKE THIS COURSE

DO NOT TAKE THIS PROFESSOR! never is in office hours and doesnt respond to emails, tests and quizzes are impossible, and he can NOT teach. He makes you feel inferior because you are not as smart as him and he is one of the laziest professors at Bradley

Okay this teacher is the worst teacher at all of Bradley. You will sit in class and be confused everyday. You will learn how to teach yourself which is not why he gets a salary. Only nerds do well in this class. There are tutors that teach this class way better then him.

He is a terrible teacher. I am usually good at Math and he does not know how to dumb it down. He is way too smart for any college student. Do NOT take this class you will regret it. No one gets an A. If you work super hard you might not even get a C and you have to teach yourself everything.

Too smart to teach beginning calculus classes. Tests impossible, quizzes even more impossible. His curves allow most to get a C but good luck on an A.

Worse professor ever. Grades are determined on quizzes and exams. He doesn't give you any points for the homework he assigns. The quizzes are difficult because he changes words around. He intentionally assigns things when someone is not in class. Take a math class with someone else. You'll get a better grade and actually learn something.

DO NOT TAKE THIS CLASS! If you have not taken a calculus course or you cannot teach yourself calculus you will do poorly in this class. He does not teach and expects you to teach yourself and ask him questions on things you could not teach yourself. The quizzes are the hardest problems possible for each section and the exams are even harder.

Dr. Lang is the most disrespectful condescending person I have ever come into contact with. He talks down to you and makes you feel inferior. He left me waiting once for an hour during office hours and never came back. AVOID AT ALL COST. I am a straight A student and got a C which killed my GPA. You have to teach yourself because he is useless.

Very bad teacher. Doesn't teach at all and thinks he's better than you.

Awful teacher. He isn't organized and his lectures make no sense. He rambles on one question for the entire class. He is cocky and isn't helpful. He doesn't prepare you well for the test and quizzes which are cumulative over the whole semester and if you ask him what to study he says everything. This isn't real math. DONT TAKE THIS CLASS!!!!!!

OMG!!!! This professor is beyond insane. Second day of class we had a quiz. Skipped an entire section assuming it was taught before--it wasn't!! Then assigns us problems that are impossible to complete! How can a person like him be allowed to teach and make it impossible--no matter how hard you try or innate abilities--to achieve an A, let alonea B

Sucks

Tests are very difficult. Pop quizzes are usually one question and are random. He uses harsh language in class that is often uncomfortable. Very unique fella... Obviously a genius with differential equations but wasn't great at teaching it. If I could do it over I would avoid Bradley's entire math department and take math somewhere else.

He is absolutely terrible. He comes to class bare foot and say to the class "lets explore". No teach us what we need to know. No calculator, no formula sheet, no curve. Tests are impossible and pop quizzes are stupid. The hardest thing i have ever taken. He is so bad. Stay clear.

It really seems like he doesn't care about the students at all. He's more concerned with making his job easier and may honestly be the worst teacher I've had in my scholastic career thus far. Last semester, I had a teacher who stopped teaching when online classes start, and just told us when the exams were, and I'd rather have him again. Terrible.

Everyday you would have a pop quiz on stuff you never understand yet. If you are really good at teaching yourself then go for him. Homework and assignments are never graded so I never know what i did wrong! Sometimes go off topic and history of math. grades consist of pop quizzes and exams. Keeps on using Respondus even tho its broken!!! Worst ever

Dr. Lang's lectures weren't organized and it was very hard to follow along. He would go on tangents all the time and never greatly answered student's questions. The quizzes will kill your grade due to how short they are. If you get a question wrong, you're already at a B on the quiz. He was also awful at responding to emails and passive aggressive,

Worst professor Ive ever had. Rambling lectures with no textbook guided presentation or anything. He did nothing but talk loosely about topics in the class. Had his own ways for math problems and then taught it horribly. Quizzes at the start of every class on stuff he hasn't taught and you don't understand yet. Super harsh grader too.

Quizzes every class (until someone complained) and he made us use a broken spyware application to make sure we weren't cheating, but all it did was screw over all his students because it barely functioned. Insisted it wasn't his fault, and that he couldn't do anything, but it was more like he didn't care enough to try. Worst prof I've ever had.

This was absolutely my worst experience with any class. Ive gotten an A in every math class before this class. He makes you learn the material with no notes and you have to recreate the formulas. If it at all possible DO NOT TAKE WITH HIM

Honestly, lecture was optional as long as you put in the work outside of class. I found it more helpful to skip lecture and learn on my own than to go to class and watch example problems. Lecture was mainly used for examples and questions, not teaching any new material. Use your textbook!!!

not a good professor. never take a class from him, it's for your own good.

Dr. Lang is a cool and funny guy, but his teaching methods simply don't do it for me. You will learn very little from attending the class, so if you take him you better be prepared to learn on your own. He has daily quizzes that are for a grade, that often take place before you have gotten the chance to fully understand the subject.

Dr Lang is smart, but his lectures were hard to understand and follow. You'll be on your own for learning most of the material. He goes over some examples in class, but they're based on what students ask. If you aren't familiar with the course material already it will be difficult to learn. Avoid taking him if possible.

Had to drop the class after learning he does quizzes every single day. He recently has been doing online quizzes even on the only day we don't have calculus 4/5 days. He is also very harsh on grading, partial credit seems impossible to get.

The man knows his stuff about the subject however he is not a good teacher. You'll mostly be teaching yourself calculus. There are quizzes everyday. Even the one day you don't have class. There is also a significant amount of homework every week. Never answered my emails. Barely gives partial credit. Smart man, bad professor. Do not take his class.

beware

Took this course for gen ed but ended up withdrawing because of the zero chance I could have passed this class. The tests were beyond heavy and had no leniency. As a professor, he lectures but is very difficult to take notes as he somewhat just talks but doesn't say anything truly important to the lesson. Do not take this course or this professor.

NO, never take his class. HE is awful.

Tests are most of the grade. Homework is 5%. You rely on the test curves. He expects you to fully understand the concepts in 1 semester at the level of math he is in. He is a smart guy, but he struggles to understand what its like to not get it.

This dude will refer to every chapter of the entire book and expect you to have every chapter memorized by topic. He does not curve his tests and makes his exams much harder than they need to be. Be prepared to use stuff from calc 2 on every exam that you haven't looked at in months btw.
