OMG!! what a mistake this class was. By far the worse class in NIU history. First off, he will teach one concept and test on another. test are very difficult-49% avg. If you are in honors do not take this class, makes u meet once a week for 1.5 hrs and usually he never shows up making u waste lot of ur time. Very nice guy very smart but cant teach

He is very hard to understand. The homework makes up most of the grade, but don't let it fool you--he doesn't go over how to do the problems and the book doesn't help at all, so good luck! The tests had to be curved so much that a 62/100 was a B... he is knowledgable of the subject, but does not know how to come down to a beginner's level..

What a nightmare! He goes into so much detail about how the formulas are derived,then expects you to know how to use them in problems that you have never been introduced to. Tests were impossible. Class average was never above a 58%. Ask him a question and he will either tell you to reread the question or leave you more confused.

I think he is a very dedicated teacher. Go to class, write down all his writing on the board and really understand them, you should be on good shape. Textbooks are just for doing homework. Take this class if you have time to come to his office hours. He eagerly explains stuff to you. To get an A, you gotta work hard on this one.

He is a good teacher, very knowledgeable on the subject. Unfortunately the PHYS 253 class was not designed very well. It is expecting you to know calculus already even though it is not a prerequisite. And Error Propagation is something you should become very familiar with. Tests are very difficult.

The tests are almost impossible to pass the class average is usually around a 40%. I somehow managed an A just by doing the HW and labs (plus he has to use a huge curve)

Ridiculous grading scales. Each TA has their own grading curve for homework. Easy to lose points on HW for format errors. Easily confused by his own notes. Gives extra credit to students that correct him. My TA taught me more than he did. Calc 2 was easier than this class. Unless you want to teach yourself, avoid! Never met anyone that liked him.

The only good this about being in Brown's class is his hilarious mannerisms. I've never seen anyone have so much trouble with erasing a whiteboard. His exams are ridiculous, but he does give partial credit so don't leave anything blank. His notes aren't helpful considering he does half of the problem wrong and doesn't correct it; I recommend Chegg.

You will need Chegg for this class. Homework is due about once a week. Takes points off easily. When in doubt, draw a picture, you will pick up points just from that. Textbook is online. Finals are two weeks away and I don't even know my grade. Lab is worth 25% of final grade. Each TA has their own grading curve. On his, 96 or higher on HW is an A.

Everything you've read below is absolutely true. He is awful, but he wasn't THAT bad. Students just like to complain. Don't rely on Chegg too much, many times they are wrong according to Dennis. Pocket that $15/month and go to the Physics Help Room. I took the final today, I don't know what I'll get for my final grade but I think it'll be a C :)

hands down the worst professor I've had to this day. He seems like he knows his stuff but is horrible at teaching it. His lectures seem to make sense and then you sit to do the hw and become instantly confused. He makes up ridiculously difficult exam questions which sometimes even TA's don't understand. Grading scale sucks too, AVOID HIM if you can

Dr. Brown is a brilliant man, but he expects his students to make the same assumptions he can make, without his doctoral degree in physics. Quizzes are insanely difficult and unlike anything you see in class or in homework. Even the TA's are left clueless by the problems he expects us to solve. When PHYS 211 is easier than 210, that is an issue.

I'm sure everyone here wants to know how this horrible man curves the class. After every quiz, he puts a bell shaped curve that includes your grade in the course. If your grade is at the class average, the curve shows that you have a C in the course. However, at the end of the semester he bumps your grade up 3 letter grades. My B became an A.

Dr. Brown gives out a lot of homework that generally doesn't prepare you for the exams. The exams are much harder than the homework. You can get by in the class without attending lectures. I've taught myself all semester and am anticipating an A. Class is heavily curved too. He is the only professor that teaches this course at NIU, so good luck.

Toughest class I have ever took. Exams are nothing like HW or problems in textbook reading. Class ave on exams were 60, 35, and 45. Score 10-15 pts above the average and you will get A/B easily. Gives lots of partial pts, so dont leave anything blank. Labs were too long and wanted detailed lab reports. Useless lecture (skip it) and just read book

Does not put grades and exams into the blackboard until end of the semester. This is frustrating because your grade in unknown through out the course. Recently, he found his exam on Chegg and decided to throw out the grade all together. There are 2 weeks left in the semester and only one grade has been entered. GOOD LUCK!

Introductory physics is NOT difficult, yet he managed to make this course the hardest thing I've ever taken.

Dennis Brown does not care about his students at all. It is two weeks before finals and he believes someone cheated on the last exam and is now not counting it for a grade. He also doesn't update his gradebook at all so you're left assuming what your grade will be. Do not take this class.

By far the hardest class and worst professor I have ever had. If you have ANY other option, don't take Physics 210 at NIU. Hardly teaches anything in a useful way, expects students to read the textbook which is impossible to understand, and the exams are exponentially harder than the homework. The final exam is today and everyone expects to fail.

Oh boy. He rambles on for hours about problems he makes up in his head, makes a mistake and expect his students to correct him all the time. If he maybe had a structured lecture and USED A TEXTBOOK, then maybe he wouldnt be so bad. Homework isnt anything like the quizzes and exams. His class is HEAVILY curved so thats one positive.

Barely puts anything into the gradebook and gives weirdly ambiguous answers when we ask him when things will be graded. Dont expect to know your grade at any given point, particularly when going into the final. Confusing lectures. The midterm and final were graded on a decent curve. Do all your assignments. Use other resources. Youll be fine..

Seems to be a nice guy, but a complete lack of understanding how to teach or provide students with adequate feedback. Won't use blackboard because "it gets too cluttered". Enjoy doing every homework assignment twice, once online and once on paper. You will probably end up just teaching yourself. Good luck.

Truly the WORST professor I have ever had. Does not put grades into the gradebook until the end of the semester so you have no idea how you are doing in the class. Takes so long to grade exams that you won't have the grade back from one exam before you take the next one. TA's aren't able to help because they don't understand the material either.

This was the worst class I've ever taken. The lectures are not helpful. The exams are ridiculously hard and nothing like the practice exams he has. We did not know our grades until after finals. It takes a lot of outside self teaching to even remotely know what is going on (& even that does not help on exams). Assigns homework before he teaches it.

Worst class I have ever taken. I think my understanding of physics actually got worse this semester. Didn't know ANYTHING about my grade until the end of the semester (after finals). Curved the lab section DOWN because he thought some of the TAs were grading too easy. Gets confused by his own notes. Curves heavily at the end of the semester.

Everything in the class is curved (exams, hw, lab). Be prepared to not know your grade until after the final. Exams were significantly more difficult than anything we learned in class. Hw was assigned before it was taught. Brown consistently got confused by his notes and is overall not a great professor. Do well in lab and on hw that's what I did.

I had him for an asynchronous astronomy class and he makes everything extra confusing. He had us sign in every week through BB even though the course was asynchronous. He expects you to submit homework into ExpertTA and hand write your notes to upload them AS A PDF to BB. He has no idea to use a computer and makes you go to his website to view HW.

This is for PHYS 283 not 253. Dr. Brown is a really great guy, but the lectures don't cover all the content so reading a lot is necessary, homeworks each take 5 hours, you don't get homework or test grades back for awhile, and theres not alot of study guides. He does give alot of extra credit and works with you to get some points back if needed.

This is for 283. This class was a living nightmare for 16 weeks. 6-8 hour hw assignments given out weekly. No grades were known except for the 5/10 hws before going into the final. Test questions so difficult that you knew you were gonna fail the exam before it started.100% graded on the hardest curve ever seen. Saying this as a warning. Good luck.
