3 exams all online and extremely easy. On the first test like half of the class got 100. The other tests were harder but still very easy. The final is optional and can't hurt your grade. Very little homework. Totally aceable course. Tim is likeable, knowledgable, and reasonable.

"You will pass this class if you do something". This quote sums up his class. exams are online and aren't very hard if you make a good equation sheet (watch out for his second exam though). Final is optional. The guy loves the stuff he talks about, and is knowledgeable, but can be hard to pay attention to in class if he drones on while talking.

Professor Cullinan is a great professor. His methods are clean, and his course is fun. He does exciting and often funny demonstrations in front of class most days, and always has a lame but funny joke somewhere in his lectures. The class is not too difficult, but still worth attending lectures.

Lectures are boring, but they give you all the information you need to do well on the tests (no book reading required). He does a really good job of letting you know what the grading is based on and what you need to do to get a certain grade. The material isn't too tough, so if you pay attention in class, you should do fine.

He is a very straightforward professor. He gives lecture slides and he doesn't intend for you to take notes. If you pay attention in class and do practice exams and problems before exams, you shouldn't have too much of a problem getting an A.

Lectures are not super interesting, but not terrible. He tries to make it interesting with jokes and demonstrations. Really not a very hard class. Gives practice exams that are almost exactly like the tests. Try, and you will get above a B.

Great teacher! Helpful and attractive!!!

Tim Cullinan is a good professor and a good man. While MATE273 is really not that interesting, and usually not that challenging, he does his best to make the class bearable. Not that it's possible at all times, but he does care about the topics and sets very clear criteria for success. There's plenty of extra credit on exams too, so don't panic.

He is a great guy and a good professor. The topics you cover can get boring at times but he honestly makes it as interesting as possible. The demos are fantastic. All the material you need to know is given in lecture, but the review sessions are also very helpful. Overall not a very difficult class if you attend lecture and put in the work.

A great class with interesting demos

Makes MAT E very interesting and cool. Heavy focus on Aerospace applications. Tough online homework but the answers are in that days lecture notes.

Cullinan is very knowledgeable about materials science and this makes it a lot easier to learn from him. Even if he doesn't cover a certain topic during the lecture, it might still come up on the homework. Despite this, everything you will ever need to know will be hidden in the lecture notes somewhere.

READ THE BOOK. Homework comes from lecture slides and book. Testing center for tests, do the practice problems he gives you as you go through each lecture with redoing the homework and reading the lecture slides and you WILL get good grades on the tests. 1st testeasy(get the highest you can), 2ndhard, lastnotsobad. follow these rulesgood grade

Decent professor, always enjoy the labs, tough grader, but tells you pretty much exactly what he wants. USE THE NOTES SHEET WELL for tests and quizzes. Labs are very interesting and talking about playing with 1/4 to 1/2 million dollar equipment is a great conversation starter. No textbook.

Good guy but no textbook and very little outside resources for the class. Tests are based completely on lectures and a little lab work. Can be difficult to get to him during his 2 office hours a week to ask him questions, decent at emailing you back though. Doesn't utilize lab much, most days lab is cancelled. Fun teacher, difficult class.

Tim is the best professor I've had at Iowa State. His lectures are very valuable and relevant to the content you're being tested on. If you do the quizzes and don't cheat on them you should be fine. The tests are very hard but if you put in the work you should be able to get a good grade. He knows his content well and is very helpful.

I Really like Tim as a person, but there are a few things about the class that make it difficult. He spends a decent amount of time on tangents that are not tested on, and there is a very large amount of material on the lecture slides. Pretty difficult exams, but doable if you spend the time to take good notes on ALL of the lectures (outside class)

Homework was easy enough to get a good grade but challenging enough to reinforce concepts. Lecture was fun and engaging. Grading was more than fair. Extra credit was given generously. Great course

Great lecturer. My only complaint is that sometimes it is hard to know what material covered in lectures is actually going to be tested

I find his lectures refreshing, He doesn't throw formulas at us and expect us to know what its practical purpose is, he explains the concept and shows how to find it, than shows how it applies to our career, That seems to be lacking in most courses. He is helpful outside of class plus the exam is basically the same thing as the practice one.

Tim is almost weirdly passionate about materials science. Tough class but a good guy. Very clear grading criteria with extra credit opportunities. Top hat in class

Tim is an excellent choice for anyone taking a materials class. He is clear on what is being asked and gives you everything you need to know in the lecture slides. Homework is not hard, tests are just homework questions, and each test has a built-in curve. On top of that, he offers easy extra credit that you should take advantage of.

Take advantage of the exam review sessions! Don't skip lecture, the demonstrations help you understand the material. Go to office hours or the help desk if you become confused.

It's hard to figure out how to study for this class. Powerpoint slides and quiz questions will cover the entirety of the exams. I think Tim is great at teaching but needs to work on clarity. The biggest struggle was finding answers to quiz Qs and figuring out what to study from Tim's massive pwrpoint slides. Don't get lazy and you can get an A.

Dr. Cullinan is an excellent communicator, and he goes to great lengths to make his lectures interesting and to make very clear the major concepts that must be understood for the exams. If you come to class, do your homework, take advantage of abundant extra credit, and ask frequent questions, you'll have a great time and learn a lot.

Tim is a very interesting lecturer in a non very interesting subject for me. He kept my attention throughout the semester and made lectures interesting. The worst part about the class were the quizzes that you get as homework for every lecture.

Material heavy class with tests requiring effort. Study the powerpoints and sit through class and the tests are manageable. Extra Credit is offered and it helps with some quizzes you may have done poorly on throughout the semester. The grading criteria is clear from the beginning of the semester and the class will most likely not be curved.

The MAT E 273 class itself provides you a lot of opportunities to succeed and get an A. Dr. Culinary himself is a great professor and does his best to make the high amounts of content in each lecture as interesting as possible. Was definitely the class I would look forward to most.

He's a likable guy and is clearly very interested in the material (heh, pun). However, he's very lecture-heavy. He has great and informative lectures, however, the notes he posts are atrocious for the purpose of self-learning. It's very difficult to learn the stuff on your own because they're so overwhelming. Easiest to just attend the lectures.

Dr. Cullinan is very enthusiastic about what he teaches and that goes a long way. The lectures are very thorough and available as a resource for doing the homework after each class. He grades exams pretty generously and offers opportunities to make up missed homework. I can't complain besides the convoluted exam seating but that's pretty minor.

Dr. Cullinan is very engaging in class, which in turn keeps you focused during lecture. He clearly tries a lot to make you laugh and helps keep the lectures light, but he also goes extremely fast and you absolutely have to go to class to understand the content on his slides. Do the quizzes by yourself, read the book, and study lots for the exams!

The best way to prepare for exams are by redoing all the quizzes. Second best thing is to read the chapter summaries in the book, as it also explains all the equations. He includes memes in lectures, and is a wholesome guy in general. Overall would recommend.

The lectures were very good. You need to be sure to know specifics for the exams though. If you take good notes and understand the math you'll do fine. Just pay attention to the lecture and give some effort to understanding. Good note taking is essential to this class.

He lectures fast; you must take notes to stay engaged. Slides are packed with info and if you don't go to class you won't know what it means. Only curve was built into tests. Do not fall behind on Quiz/HW. He answers questions all times of day, and QUICKLY! Answered my questions at least 3 times out of class. Tests are scantron. Nice guy, but no BS

Lectures so fast it is nearly impossible to take notes, but slides are posted so it isn't that big of an issue. Provides many resources for tests and answers questions fast. Exams are straightforward and simple, also include a curve.

I have to admit he lives up to the title Turbo Tim. He lectures fast, and you have to be on top of taking the important notes. Exams are out of 110%, three quizzes a week with 3 attempts, online. All exams are multiple choice, so no partial credit. He is engaging and encourages questions in lecture. The math can be hard, as it is not covered well.

MatE 273 can be challenging--there's a lot of chemistry, which many students have probably forgotten. Dr. Cullinan was always very accessible and friendly outside of class. Tests were rigid, mostly because of class size. Changed my major to MatE because of this class. TA'd for 273 the following year. Great teacher, tough (but fascinating) course.

I took MATE 273 with Turbo Tim. This class is extremely difficult and covers a bunch of content. What I like most about Tim is the insight that he gives into the industry. Pointing out things that he has personally used in his experience working. Yes the clas is hard but don't put all of the blame on Tim.

Tim is awesome. He is a great guy and he really cares about the material (wink wink).

He has expectations that students will take time to understand the content. Considering the difficulty and large amount of content, this is not unreasonable. Taking time to understand the content makes the class very easy. No homework, only quizzes with 3 attempts which are easy to get 100% on if you attend class and pay attention. Funny guy too.

Very well-respected materials scientist; cares very much about the education of new engineering students in MAT E 273. Enjoyed the class, was straightforward, and 10 points of extra credit on each exam.

This class with Dr. Cullinan was one of my favorite classes ever as a mechanical engineering student. I learned A LOT from his lectures. The "quizzes" that were really homework assignments were not bad, the exams were similar to the quizzes, and the TA office hours were very helpful and offered multiple times each day of the week.

The name of Turbo-Tim lives up. He talks fast and has some of the most content full lectures of any class I've taken. Minimal outside of class work if you go to class and pay attention. Very interesting and I really enjoyed the class
