Dukes was fine at lecture. His presentation was a little dry but it's mechanics so I can't blame him. If you've taken AP physics before this class will be pretty straightforward and if you haven't just read the slides before the exam and make sure to understand Mastering. You can't really complain about the exams since there was a pretty good curve.

Dukes is a fine lecturer. It's not an interesting class--though to be fair, the material itself is pretty boring--but some of the demos are cool and you have to go because of iClicker questions anyway. My main issue with Dukes is that he didn't care if anyone actually learned the material--like if there was an iClicker question that 80% of the class got wrong, you'd think he would go over the relevant concepts so that people understand, right? Nope, he just moves on. Happened a bunch of times throughout the semester, especially towards the end when things get more complicated.

Also, he doesn't post lecture notes online until he's done teaching them, which is frequently after the related MasteringPhysics homework is due. So how are you supposed to know the equations and concepts that you need to solve the homework problems? Chegg is your friend!

Overall, this course is not easy (regardless of professor) but it's possible to do well if you're willing to put in the effort. I never went to Dukes' office hours but I heard mixed comments about how helpful he was in person. I found that just flipping through his slideshows was the most helpful way to study, especially since he'll occasionally recycle clicker questions directly from the slideshows to the exams. The three midterms and the final are all difficult but they're all curved pretty generously, so you'll be alright as long as you study.

Dukes is a boring lecturer. MasteringPhysics taught me absolutely nothing. Do not go into the midterms expecting to get all the questions right. They are all multiple choice but even the highest scores normally aren't better than 12/15. The only things I will remember from this class is "Oh! Iclicker question", Jaguar XKRs, and Al the Demo Guy. Without Al this class would be total chaos because Dukes is so so clueless during the demos.

love Dukes even though this class wasn't easy. Demos in class made this one of my favorite classes of the semester. The tests were hard and sometimes the homework got ahead of the material but overall a good time

Seriously, don't take this course unless you need to. His lectures are boring and people only go for the clicker questions; you can do other homework while answering a question or two every 10 minutes or so. Dukes can be condescending if you ask him a question and he wonders why you don't understand a concept. His lectures are filled with random information that you won't need for the tests, and he reads formulas to you that are on the formula sheet. The demos are cool though and Al the demo guy is the real MVP. The tests are really difficult and they are only 15 multiple choice questions. I found the best way to study was to go through the powerpoints the night or two before the test and just skip the fluff. The best part of this class was when he would show basketball clips from March Madness at the beginning of class.

Dukes isn't horrible, but he isn't great. The class was easier for me because I had taken AP physics 1 and 2 in high school, and Dukes did fine teaching it as a refresher course, but for someone learning the concepts for the first time it may be more difficult. The demonstrations are useful, but he doesn't explain them well, so I would recommend looking up better versions online because those really helped me get the concepts. Study clicker questions for tests, because he will sometimes take them and use them verbatim on tests. Also, he doesn't teach fundamental theories well, so it could be useful to look up really basic questions that don't use numbers because those will inevitably show up on tests.

This class is hard but Dukes is an okay professor; he is very approachable and he does plenty of demos. Only take this class if you have to because it is hard to do well in even though there is a generous curve. The 3 midterms are quite tricky and hard to study for, and sometimes your grade on tests is a coin flip as all the test Dukes gives are multiple choice and only 15 questions. The final is 40 multiple choice and they are a bit simpler than the 3 midterms but still difficult.

You spend most of the class going over equations that are given to you on the formula sheet for the exams. Also, much of class is spent going over random physics topics that you do not need to know for the exams.

The exams in this class were very difficult. Although each exam was curved, it is still difficult to do well in this course-- even if you read the textbook and pay attention in class.

Dukes is not good. The whole department to be honest is not good. I think its quite unnecessary that all e school majors have to take this class to be honest. Dukes has a really monotone voice and people only go to class to get clicker points you don't really learn anything otherwise. I tried to actively take notes in class for 3/4 the semester and it resulted in nothing. The only way people learn is if they read the textbook or do Mastering Physics and even then the tests are so crazy hard that you have no clue where they pulled out these questions from. The final is even harder. None of the TAs or professor Dukes have helpful office hours so you basically feel trapped.
