He can be a bit scatterbrained, but overall, he's a good professor. He answers all questions asked fully and is a nice guy. This class has some very strange material. Put some work into this class and do all the homework and you should get a good grade. Not too hard.

Orum teaches lectures that tend to be very boring, and all notes are in lecture. The examples he gives are useful. His HW was all from the book, and the TAs pretend to check your work every week, so its a guaranteed 100% in HW to bump up your grade. Be prepared to work to understand 256 since its a hard class, but he teaches and tests fairly.

Orum wasn't too bad. You could use homework for quizzes, and a good 40% of your grade is an easy 100 percent, like recitation, homework and quizzes. He was a good lecturer in class and wasn't disorganized at all. However, his midterm was really hard though his final was easier. His tests overall, are very challenging, and there is no curve.

Dr. Orum is a great calculus professor who really knows his stuff. He's always willing to clarify any questions after lecture and makes sure that everyone is on the same page before moving on in lecture. His class examples were thorough and would cover every step. He was also very organized and prepared.

I dont understand why Chris has so many bad reviews. He was super nice and everything on assignments and tests was covered in class. If you didnt understand something he was easy to contact via email, I never went to his office hour so I cant comment on that. I highly recommend him, at least for this class.

I think Chris is a really nice guy and good teacher, he knows what he is talking about and wants you to learn. His homework quizzes and tests are all reasonable, and he seems like a good guy.

Dr. Orum is a great professor. He's pretty easy to follow and his tests are very straightforward. Really nice guy.

As someone who was unsure of committing to a math minor, Chris really solidified it for me. The labs that he made the class do were really helpful stepping stones towards tackling the somewhat harder homework problems, and while he is very much the type of professor that uses pre-requisite courses to their fullest, he is very understanding.

Useful homework assignments that really helped with practicing the material. Tests were reasonable. His lectures were straightforward and he explained the material well, with exceptions of the students' knowledge being clear.

Real nice guy and none of his tests try to trick you. If you pay regular attention you'll do very well in his class.

Good professor overall. He is a bit scatter brained during lectures, but that's true for a majority of the math department. He gives good applicable examples in class, and the homework problems are well chosen. You have unlimited tries to do the online homework, and written homework is graded on completion. The tests are difficult but not impossibl

I loved taking MTH 254 with Chris! His lectures were really great because of the obvious effort he put in to help us learn. He can go pretty fast sometimes, but there's a lot to cover. I would recommend reading the chapter before class. The tests were straight-forward and there were never surprises. The online homework problems were also helpful!

While he didn't always answer questions in the clearest way, Orum always came to lectures very prepared and his lectures were always really organized and clear. It is recommended to read the textbook chapters before lectures but not necessary. Some test questions are taken from recitation activities so make sure you master those problems.

His explanations could be a little confusing at times, but overall a great math professor. His notes were very organized and I always felt like he was fully prepared for each lecture, and cared about students' understanding of the materials. Review chapters before class, and review notes after, spend plenty of time on studying/homework!

Good lectures, will answer questions thoroughly well designed labs homeworks are challenging but not impossibly so reading will help you succeed

Does a good job overall, if you ask him questions outside class he is always ready to help and cares. The proofs and insight during lectures are not saved online so attendance is important, but the grading is fair to balance that.

Orum is a very organized lecturer. Do the homework and make sure you understand how to do it, and you'll be fine on exams.

Like others have mentioned, Dr. Orum is a great teacher, albeit a bit dry. He is very accommodating in lectures and is always willing to answer questions. Unfortunately, the class was rather disorganized, and tests were tricky in ways that didn't seem necessary. Overall, don't be afraid to take his class, just put in the work and you'll be fine.

I took this class winter 2021, aka, over zoom. He's very good at explaining things and answers questions very clearly(makes sure he actually answers your question). Class was organized, mixture of online and written homework. Two midterms, no trick questions. It helped me to take textbook notes but not necessary. Could be considered boring to some

His class is amazing! I took four classes with him at OSU (MTH251, MTH341, MTH342, AND MTH355), I really like his teaching style: clear and specific. He cares about his students and is willing to give us extra office hours if needed.

Orum is an excellent professor. His lectures are comprehensive, sometimes a little fast, but he explains all the concepts of calculus in a simple and logical manner. He engages with the class a lot and will answer any questions very directly and helpfully. Knewton-Alta is tedious and terrible, but i would be lying if i said it didn't help me learn

Chris is great at communicating and as long as you go to class and recitation you shouldn't have any issues. Knewton Alta assignments always seemed way above what we were doing in class but you only had to complete 80% of each assignment to get a 100. He's very understanding and wants you to succeed.

You will have a online knewton alta assignment, a written hw, and 2 preclass survey quizzes each week. I But I really love how he teaches, he's excited about the math and itnerested so it rubbed on me too. Good teacher. Theres a bit of homework, but TBH it's necessary to pass the class, so it's not just a him thing. grades 4 corectnes on writen hw

There are 5 Units, and 5 tests. The Unit 5 Test is cumulative. Very consistent weekly homework load. Extremely accessible outside of class. Text book is free and online.

Very organized class. He teaches you a new topic, gives you a worksheet to work on, then goes over the worksheet as a class and how to do it. His handwriting is the best I’ve seen from a teacher and it is very easy to follow his work. Does a solid job explaining the concepts

Chris was the only professor at my current three years that ever learned my name. He is very helpful and makes sure to thoroughly answer questions, and has great lectures. He always offered a zoom option and an in person option for whoever couldn't make it to class for whatever reason. Going to class offered a small amount of participation points.

The professor was very organized and easy to learn from during lectures. The class overall is on the more difficult side but the professor teaches in a way that in understandable. There is a lot of material that needs to be covered so lectures are heavy but if you attend it is definitely manageable.

Chris was a very good professor who takes the time to answer questions in lectures and do proofs to answer them. He knows what he is talking about and is very good at teaching and explaining what is going to be on the tests. Generous with giving opportunities to boost your grade. The negative reviews come from the class itself not the instructor.

Orum is a great lecturer. Pay attention for the whole period and everything will connect (most days) that being said, the class (which orum doesnt have complete control over) is not great. Knewton alta was great in the lower calculus courses, but in 254 it is a waste of time that reinforces nothing. Written homework is OK. Tests are easy.

254 is a difficult course, but I felt Orum did a good job explaining the material. The lectures were solid, and lecture videos/supplemental materials were regularly posted on the course canvas page. The textbook used in the course is also available online for free.

Lectures, homework, recitation, book, and the final are all tangentially related minus the textbook with midterms. I aced 3/4 of the midterms relying mostly on the textbook and achieve however the final was humbling as he pulled information almost exclusively from the first few weeks and from previously unrelated content from his lectures.

AND THIS IS WHY HE IS THE GOAT. THE GOAT!

Textbook was free. This class takes up a lot of time and is very difficult, but Dr. Orum did a good job of teaching the theory behind all the math. Ask questions in class. Making a study group is heavily recommended if you want to do well. Dr. Orum sometimes forgot to mention some topics but would push back assignments that needed them until taught

Absolutely goated. Don't hate the player, hate the game

Free textbook but you have to pay for acheive. Classes are lecture heavy but vector calc is a lot of material. Orum was able to explain the process behind the math and you will come out of the course with a solid understanding.

Incredible teacher who will teach you what you need to know. If you really don't understand something, go up to him and ask questions after class. He will be sure to answer them. Most weeks, he hosts office hours before homework is due to help students with last minute questions. Lots of homework, but it's all prep for the exams, which are easier!

This is a difficult course, but Orum teaches it well. He clearly knows what he is talking about, and his drawings are very good. He responds very quickly to emails. The only downside is that he taught on a chalkboard which is hard to see when he is standing in front of it.

This class has a lot of hard material but Orum tackles it well to make sure students have a solid understanding of complex concepts and problems. He is very responsive over email and holds office hours before upcoming quizzes. There are four quizzes throughout the term and a final, but they're easier than the homework.

Chirs is a great math teacher. His class is a lot of work, but that's any math class. He's very good at explaining things. If you show up to lectures/recitations and put in the work, you will be fine in this class. He posts notes on Canvas after every lecture as well in case you miss one. There is a textbook but it's free.

Orum truly is the most goated math teacher I've had at OSU. This is a hard course, but he explains things clearly and well. Hes a sweet guy and cares about the student's understanding. Be prepared to take a lot of in-person notes on paper. Sit up front and enjoy the best 254 teacher.

Orum was probably one of the best math teachers I've had. He took the time to explain things carefully and held office hours constantly to help students who got stuck. This class is definitely challenging, but if you take advantage of his office hours and tutoring at the MSLC, you should be fine. Would definitely take a class from Orum again.

Since I had already learned differential calc in high school this class was easy however he does expect you to already know diff calc and it's just a revision for everyone. However, the ta is very helpful and he is willing to help you learn.

He is very good with teaching the content of this class. Lots of homework, but it really helps you nail down the concepts, especially when problems just build upon each other. The main problem? The way he ran his two quizzes for the course. There was just barely enough time for a select few to complete a four pager in 15-20 minutes.

He gives study guides before every exam which you should definitely go through before every one. Lots of online homework but they make sure you really understand one concept and really helpful hints on each problem

The class itself is a difficult class. Beware of mini exam 2! It is a very difficult exam, especially compared to mini exam 1. Great professor though, great thorough lectures that are very consistent. His notes and logical process for teaching was fantastic.

My second class taken with Orum (took him for 251 too). I'm a big fan of his teaching style. Lectures really help to develop a deep understanding of concepts. He's clearly very passionate about what he teaches. Heavy workload for this class but it's necessary to get comfortable with the material. Mandatory studio is annoying though.

Great teacher, his lectures work very, very well for me. Occasionally he will not fully understand a student's question, or will make some arithmetic error on the board, but he makes concepts quite easy to understand overall. I recommend sitting near the front of class so you can see the board easier.

Chris Orum is my favorite math professor of all time. His tests are a little harder than other professors, but I've learned more from him than anyone else. I took MTH 256 with him and got an A+. He had a free textbook which was awesome, but you don't have to read it if you go to lecture and take notes. I also see him at Dixon a lot. He's the goat.

Chris is the best math professor and teacher I've ever had. He's very good at visual concepts and he will always work up on the board. He's wonderful and doesn't grade harsh at all which is very helpful to give us a buffer on the exams.

His lectures are packed and sometimes gets lost on tangents explaining proofs and why certain problems CANT be solved a certain way, but overall he did a good job and I learned a lot. Lots of homework, but that is expected. Exams were straight forward, but you get no notes or even calculator so sometimes were difficult.

Chris was very straight forward. He was good at answering questions and you can tell he wanted to help you as much as he can.

I would say that this class was about 70% of my 15 credit courseload the term I took it. It is an insane amount of homework but if you put in the work and complete all assignments you will be successful. The lectures aren't eventful but Orum teaches the material well and provides study guides for each exam.

This class is a bit of work especially if you haven't taken calc before. He's very relaxed and good at answering question.

I liked Chris, he had a very traditional lecture teaching style that works very well for me while also incorporating some group work into lecture/recitation that made the material stick. The tests were much easier than the homework which there is a lot of, but that seems consistent with other MTH254 classes.

Orum's lectures are clear and engaging, though the class can be challenging. Attending studio and utilizing resources like the textbook and unstuck AI are key to success. The workload is heavy but manageable if you stay on top of the material.

Took his 251 math class. Overall, good time, the class is very lecture heavy and can get boring and there is a lot of HW but he does prepare you well. If this is your first time taking calc I can see how it can be harder but if you are coming in with experience it will be a cake walk. He is very accommodating if you ask though at will work with you

Chris Auram is the goat

Chris is my Goat I'm not even kidding. I failed precalc in high school, so I was very nervous about taking Calc 251 last term but Chris is so incredibly good at explaining concepts that it was all super easy to absorb. He's older, but he is very friendly and really knows his stuff. Best math teacher I've had to date.

He is pretty old fashioned and a little rude. But he is probably your best bet if you are taking vector.

Vector Calc is a difficult class, but he made it a lot easier than it could've been. He has a traditional teaching style, but it works for me. Was very helpful during his office hours.

He is the textbook example of a standard math professor. He lectures, you take notes, you do some homework, and take some tests. Main criticism is that I think the content on the tests was a bit less similar to the homework, but he was a solid professor and you'll succeed if you simply do the work and go to class.

Dr. Orum's class was tough, more so due to the OSU Vector calc curriculum than him, but his lectures were jam-packed with information on the chalkboard so you have to pay attention and write quick. Tests were mostly what you expect, and he prepares you pretty well all things considered.

Chris is a funny older man who is passionate about what he teaches. I learned a lot about vector calc from him.
