DO NOT TAKE! Hardest class I have ever taken. Only class I have ever failed in my life. I got an A in 408C and could still not understand what he was explaining. TA was not helpful at all either and could not even explain all the homework questions. Tests and quizzes were not an accurate representation of the homework that I spent hours on.

The class material is difficult enough, and Dr. Rusin's explanations during class are subpar at best. I really relied on the TA for this class in order to learn the material and finish quest assignments. Often times he wouldn't go over stuff in class that was on the homework for that week. Difficult to understand during class.

Rusin is not a good professor. Thankfully I took calculus in high school, so I was able to teach myself. He doen't lecture because its a flipped classroom model, so you can teach yourself off of the modules.

Intro to Math was not as easy as it sounds. He clearly has an intrest in Math, but he failed to make his class organized.

You can tell he really knows his stuff, but it is still very difficult to understand the points he tries to get across.

Lectures are useless. Takes the whole class to go over one problem. Added with that, the online notes (it's a flipped classroom) don"t help. Be ready to self-teach. Tests consist of 5-6 multiple choice and 2 free response, so you miss one problem and you're down a full letter grade. The class is on a curve, but not a very good one. DO NOT TAKE!!!!

This was the hardest class I've ever taken. Tests are not too long but more conceptual than the homework and expect to go to CalcLab a lot and teach yourself throughout the semester.

He spends a lot more time on theory and not very much time on actual problems, especially things that we find on exams.

Also, he makes a lot of his exams multiple choice because he's admittedly too lazy to grade, so any error can kill your score.

Because of the flipped classroom, he does very little actual teaching and spends more time on useless theory. He gets through one or two problems a class.

Multiple choice problems from quest make up the majority of the test grade and there is no partial credit. The curve is lenient but will by no means carry you to an easy A.

Rusin made 427L unexpectedly difficult. The lectures were useless. Tests did not reflect lecture or homeworks. Tests were hard, all tests were curved. My colleagues in the other 427L were breezing through the class. The thing which triggered me most is when the entire class is failing the tests and Rusin blames us for not trying hard enough

I took calc in high school, so it was a pretty straightforward class, but he doesn't know how to lecture at all and will go on unrelated tangents about things that he finds interesting rather than the content he's supposed to be teaching. At least curves are good?

Professor Rusin is the worst math teacher I have ever encountered. His lectures are absolutely worthless. He assigns a heinous amount of home work and learning modules that do not help you learn at all. He is ok at best during office hours and if you don't have an amazing t.a. you are doomed.

This was the worst math class experience ever, he went on so many theoretical tangents, lectures were literally useless, discussion sessions were so unstructured and we just had to do our homework. If you're decent at self-studying, do not waste your time by going to class - just do the Quest homeworks/reviews because he uses those for exams.

Do not take this class. Dr. Rusin's lectures are basically just tangents over random, irrelevant math theories and he makes no effort to prepare you for his exams. There are 5 homework assignments due every week which can take HOURS. The exams are incredible difficult and he refuses to curve them, even after both exams had an average of %50.

Genuinely the worst math prof ever. He's a nice guy generally, but HE CAN NOT TEACH. He's one of those people who is so smart that he doesn't know how to explain the content. Did literally 30+ hours of outside tutoring and will still probably make a D. Also, there are so. many. homeworks. They take forever too. Hope he curves the course.

I just want to start by saying that my low rating is not because this class is hard. This class is EXTREMELY DIFFICULT and requires HOURS of studying/work. Professor Rusin's lectures did not help me at all during this semester and had just talked about nonsense during them. There are so many homework's and test averages are around 55. CAREFUL!!!!

Guys. Beware. David is an interesting character, but he cannot clearly explain anything for the life of him. When questions are asked, he never answers them appropriately, and he starts talking about what he is doing in his other classes. He refused to take accountability when he asked what went wrong on the exams and just deflected and blamed us.

He is a nice guy, but his lectures really aren't that helpful. You're better off teaching yourself and using the homeworks which are a direct reflection of the exams.

I thought David structured a good math course based off calc2/3 concepts. The easy in class assignments gave us a 10% grade swing . Although the HW's were extensive, they were pretty representative of what was shown in the exams. His lectures weren't too bad either. Overall not a bad teacher and someone who cares about the success of his students

praying to GOD for a curve on this class. David is a nice dude, but man he cant teach at all. tests are difficult, and there was an obscene amount of homework. felt like no matter how hard i tried i couldn't succeed - wasn't much help when i brought this up in OH either. tests uncurved, despite the awful averages. hoping for course curve.

Horrible professor, I truly regret taking this class. He refuses to embrace modern technology, lectures consist of watching him live transcribe derivations on printer paper as he talks. Poorly prepared lectures which would be tenfold better if he just learned to use 3d desmos during the multivariable topics lol. Don't take!

Professor Rusin is a kind guy, but he sucks at teaching in front of a class. Half the time, the lectures don't really make sense, and you never really know what the purpose of the lecture was. All attendance is optional, so skipping lectures really makes no difference. I will say, though the his office hours were helpful. First exam was bad...

He is a really nice person and extremely smart, but he can't dumb things down in lecture. Kept repeating throughout the course "now you guys know as much as I do." It isn't impossible to succeed in his class, it was just very hard for me to, as I was taking many credit hours. Make sure to spend time doing the hws and fully understand them.

This class was pretty tough. The class average sat around a 55 for Exam 1 and 2, so they changed the final to replace 2 lowest midterms. His lectures were him writing on a piece of paper, but overall they did help me understand the topics. Use the textbook and TA's to pass this class.

You will have a hard time in his class if you do not remember past calculus topics well. He provides homework problems that he will fail to discuss in lecture. His lectures aren't helpful whatsoever, and he will want to test you on abstract math. It is possible to pass. He is a nice person, but he will NOT make it easy.

Dave cannot lecture. Half of the class would never show up because his lectures are always horrendous and full of tangents on things that we did not need to know. He is very abrasive and if he thinks a question is stupid he will let you know. Tests are unnecessarily hard, but he does curve. Genuinely made me loose my love for calculus.

This class was basically a teach yourself type of class, except the exams were insanely difficult. That said, the exams are curved and they are doable IF you practice a ton of homework questions. It is possible to get an A, but do not treat this class lightly if that is your goal. Rusin's a nice guy though, and he is semi helpful at times.

Could rely on more lectures and less homework, and very tough with grading tests, but other than that M 408D is a hard subject regardless of who teaches it.

DONT TAKE. I use to think I was good at math before dave. There are no curves on any of the test. The class averages on the first tests were 50 and 60, and that was with a handful of people cheating. He seems like a nice fella, but he speaks in riddles. Not one lecture did I walk out feeling I learned something. Shoutout to Organic Chemistry Tutor.

This was definitely a challenging course. Lectures are very confusing and irrelevant to course material, and professor is rude when you ask questions. I had already taken Calc II at a community college, so I thought I had a solid foundation. Despite this, I failed every exam. Luckily, Dr. Rusin gives generous curves, so “technically” I passed.

I've taken through linear algebra in high school and wanted to get a minor in math. I dropped that minor because of this class. David's really nice and VERY smart. But since he's so smart, he is simply incomprehensible. Genuinely did my bio homework in that class every lecture. I like Dave, but maybe higher level math would be best for him.

Rusin is the worst professor I've had. I went to every single lecture (although many didn't) and it was a waste of time because he is a genius who cannot explain topics in a simple manner. I took calc BC and got a 4, yet this class was my biggest struggle despite already "knowing" the content. I do not reccommend unless you want to spend 10+hrs/wk

Avoid Rusin 408D. He's a poor lecturer who routinely goes on tangents instead of covering the actual material. Would highly recommend skipping lectures and self-studying. The textbook is good, and he assigns tons of Quest homework, which the exams are heavily based on. Best bet tho is to take another prof. 408D is alr tough, dont make it harder
