I only had this professor for a few weeks because I dropped. He explained the material very clearly and thoroughly but he is difficult. No curves or anything like that. He's very "by the book" and dry, not a very pleasant or nice person but he does explain things well.

Good teacher, explains thing every well, hard test though. If you work hard in this class you will do well, if you dont work hard, dont even attempt to take it.

Orr is not the easiest professor, he's very much by the book but overall I thought that he was quite helpful in explaining the material. The only thing is that your grade consists of your four test grades but studying the notes and looking at the homework will definitely help.

DOnt take this class during the summmer. he goes too fast,dont review for the examans,Hardest exercises in the exam,if you don’t do your homework, there is no way you pass this class. HE doesnt make a curve for the gardes so if you are willing for a miracle at the endof the semester.IT Wont happen,a positive thing is that he teaches really good

Professor Orr is great. when he teaches you'll be able to understand everything. Yes, his tests are extremely hard but as long as you are willing to study and do your homework you should be ok. NO CURVEs, when you add up your four test scores and divide by four thats what you'll get. It's hard but if you want to learn and work hard, take his class.

Underrated teacher. He knows his stuff and teaches very clearly. He usually uses his whole 75 minutes to teach on each class. His tests are difficult, but doing your optional homework helps a lot. All tests are curved by 5 points and he often gives partial credit when you make a little mistake on a problem. If you are serious on math, take him.

I think that he is an EXCELLENT teacher. Before each class he goes over the problems you need help in. He DOES NOT make you feel stupid. If you do your homework and ask questions, you should pass. I TOTALLY recommend his class, but you have to do the work. If you don't, you will fail the class. I defenitely recommend him. I thought he was GREAT!!

You'll learn alot in his class.

A math teacher with exceptional teaching skills who graduated with a 4.0 according to a website. He helps you on the homework and replies to emails even on vacation, althrough he disappointed when not grading a test before the drop deadline. His tests are easy and rarely tricky if you do your Homework, curbs 5 points up, and gives partial credits.

I failed mac 1105 twice. I took it a third time with Doug and I got a B. Do your H/W and go to class and you should be fine. He's pretty good at teaching this God forsaken subject.

He's tough, but fair. If you just need to pass, he's hard, but if are going to take further math courses, you will really know your stuff if you pass.

He is a good teacher, but you need to study and do homeworks for his tests, he gives 4 tests including the final. He explained all sections very GOOD. I will recommend this teacher.

very nice guy. this was my second time taking him (alg&calc) and i failed again. explains really well but makes exams extremely difficult. doesnt take attendance and doesnt curve or give extra credit

do your homework and you'll be fine. Overall hes a good teacher. His tests are just like the homework!

he was an awesome teacher. he explained everything very well. everyone who gave him a bad rating is probably retarded and probably didnt go to class. :)

Although I must agree with prior statements that he knows his material. And knows it to the tee, he is a very harsh grader, did not give partial credit on his tests. But if you are dedicated on knowing every single aspect of theorems, then you will do great. If you do not like to study hard, don't even bother taking the class.

Orr knows his stuff!! First test you need to know over 75 vocabulary words, and the rest of the test are a mixture of theorems and problems, the problems are exactly like the homework, if you want to do well go to class and do the homework. Beware you will need to dedicate great deal of time and effort in order too pass.

Study Study Study!!! You need to put great effort and time into this class. After the first test 70% of the class stop showing up, but if you try you can pass!

Good teacher, I actually learned quite a bit from this guy. Im actually really happy he explained multi to us in one of the last classes. It really helped me later with advanced calc.

This teacher is extremely good at explaining math. He is on point and sticks to the syllabus. Homework and attendance is not mandatory but I recommend it. The tests are a bit hard but if you study well and do homework, you should be fine.

Most people thought his class was very difficult but if you actually go to class pay attention and do a little more than the assigned homework you should be more than ok.

A really sarcastic guy, but speaks very clearly and knows what he's talking about. I took him for summer so things were really quick. Do the assigned homework, even though it's not required. You'll need it. He can be rude but also gives a lot of small breaks; 5-10 point bonuses on tests, sometimes. 3 tests and a final; final replaces lowest test.

all these people saying thet he is not good , well he is dont pay attetin to what the other people say because they are probably not insterested in school and want every to be fed to them in their mouth. go to his class do the homework and you have a garanteed A

HE IS AN EXCELLENT PROFESSOR. I DONT KNOW WHATS WRONG WITH ALL THESE PPL THAT SAY HE HIS BAD. HE EXPLAINS MATH CRYSTAL CLEAR. A LOT OF PPL DONT GO TO CLASS SINCE ITS NOT MANDATORY THAT PROBABLY WHY THEY GOT BAD GRADES...GO TO CLASS AND DO THE HW U WILL GET AN A. AND HE USES THE SAME PROBLEMS FROM THE HW ON THE TESTS.!

EVERYONE HERE IS JUST LAZY...HE IS A GREAT TEACHER. EXPLAINS MATH PERFECTLY IF U GO TO CLASS ITS IMPOSSIBLE TO FAIL. DO THE HW!! ITS THE SAME PROBLEMS ON THE TEST.

He was not a bad professor. He was helpful if you went to his office hours, he did try to help you out. Although I would not take this class in the summer, it is alot of work. I really recommend this class if it is offered in the fall or spring semesters. Homework is not mandatory and neither is attendance, but if you do not go to class you will fa

Yo do not take thsi class with him period

He is okay. You really need to put time and effort into this class. I would be at the library everyday studying and I passed with a C+(and i was the 5 highest grade in the class) do the math! A lot of people fail his class, but if you have time to put into the class then you will do OK.

I got a B+. I could have got an A, but I slacked. He is a very good prof ... very Systematic. He will teach everything step by step. He can sound a bit sarcastic at times, but disregard that. If you do the HW, the exams will be like a piece of cake. Very Very good prof. I would recommend him to anyone.

Geom for Educators: Very clear math teacher. Very good at explaining things. This class is very easy at the beginning but gets harder with the proofs. He is a good teacher but you still have to study of course. Do problems in the book and study his notes. He is very helpful. Highly recommended.

Professor Orr is excellent. He is very clear. He teaches everything step by step, and is open to questions. He is a little sarcastic at times (some might find it offensive), but I found it rather funny. He does not use MyMathLab (which is great).

Overall a great professor, very clear at explaining math. Don't take him if you expect to pass the class without doing anything. Getting an A shouldnt be hard if you do all the HWs and if you have any questions you can ask him to explain it in the beginning of the class. Plus he grades exams very fair. STRONGLY RECOMMENDED IF YOU WANT TO LEARN!

The key to doing well in this class is simple- DO THE HOMEWORK. If you don't do the homework, rest assured, you will probably fail. If you put in the time and do the HW you should get at least a B. His tests are challenging but he is very helpful as far as office hours and he teaches in a very clear and straightforward manner. Good Professor.

Professor Orr is a great teacher. His lecturers are organized, he encourages people to ask questions in class, His tests are fair. If you do your homeoworks and take good notes in class, you should pass his test with at least a B. Also, he has really neat handwriting, so taking good note was a breeze...

insanely hard class but the first test and the final are easy, just gotta study definitions like mad, replaces lowest test score with final exam grade, i got a 73, 63, 48, and a 32, but managed to pass with a C, because i got a 78 on the final only reason i passed was becuase of his grading policy, and his curving the last 2 tests, very helpful

GO TO CLASS & ASK ?'s! Do ALL OF THE HOMEWORK. 90% of his tests come from problems in the homework (even not odd). Unfortunately, he includes some of the HARDEST homework problems so if you think the exams can't be that hard, think again. Lowest exam score replaced with Final. Study those e & ln problems VERY WELL. He LOVES those.

He's not as bad as everyone thinks. He's really organized and explains everything very clearly. His tests are hard but if you study you'll get it. If you could get a better teacher do it, but if you have to resort to a not so great teacher then take him. HES NOT THAT BAD, HE KNOWS HIS STUFF!

I dont understand all of the comments here saying that this guy is terrible, he is an amazing professor who really knows his stuff and knows how to explain it perfectly, yes his test are hard but if you do what your supposed to do, go to class and do your homework you will pass, really nice guy too.

I started going to class this week to learn the material on test #5. Prior to this I learned doing the online homework and quizzes, enough so to have 70-96-97-97 on the first four tests. Straight-forward teacher. No trick questions on his tests and they are quite easy if you make sure you know how to work problems from the sections on the test.

He is okay. His class is not atrociously difficult nor outrageously easy. He is kind of rude sometimes and I kinda felt embarrassed for some people whom he was rude to. I never went during office hours to ask anything but I think he tends to be nicer then. Every math teacher has sucky ratings...you might as well take him.

He is really good at explaining things! But he makes A LOT of sarcastic remarks but just dont take them personally. TAKE ADVANTAGE OF HIS HELP DURING HIS OFFICE HOURS! If you dont understand something GO TO HIM DURING OFFICE HOURS and he will explain! But he is very strict! I was one point away from an A- and he would not give it to me! Made me cry

Best math teacher I've ever had!!! He explains everything so clear and if you have a question he has absolutely no problem in answering it right then and there with no attitude. Very professional, always on time, and cares very much about you learning. His tests are easy if you do your online work and especially the practice homework questions. A++

He's really helpful, if you ask for help. He can be a bit boring, but at least he knows his stuff. He tends to grade tests pretty specifically (he kinda has to, being that it is a MATH class). He has 4 tests, one final. Drops the lowest and the final is cummulative. Study the definitions, theorems and do the homework and your good.

He is an extremely good teacher, covers everything step by step. And as long as you go to class and do the homework, the exams are easy! He is helpful if you asks questions too. He's not a professor you can be buddy-buddy with. He's just in and out, and can be a little arrogant sometimes... However his ability to teach math well makes up for that!

His exams are somewhat challenging, but his lectures are very detailed and well explained. Excellent for learning, but not necessarily the best for your grade unless you put in the work.

He's a great lecturer. Isn't very lenient with his grading but emphasizes you keep up with the homework and online work. One con I'd mention about him is that it's really his way or the highway in terms of solving math problems. I would take him again.

Unless you are willing to put in hours and HOURSSS of your time studying for this class,DO NOT TAKE HIM. It is extremely hard. He explains everything pretty clearly and you'll THINK you understand it when you're doing the homework but when it comes to the tests,the questions are completely different and they are impossible!! Better not to take him

He's a really good teacher. His humor may come off as cynical at first but I genuinely think he's a nice guy. He explains things well and makes himself available to you if you need help. He also grades pretty leniently comparatively to other math teachers I've had. Trig isn't easy so you'll need to put effort in regardless. I'd recommend him.

Great Teacher. Gives you all the information you need to pass. Doesn't check homework but you must do it if you want to pass. Very clear and encourages students to ask questions.5 exams and drops the lowest exam and replaces it with final. I passed with an A.

Overall, he is a good and clear teacher but his tests can be hard. He likes to see his students fail in all honesty so be prepared to do the homework because he puts hard questions on his tests and go to every class.

I went only to a handful of lectures. I used the online homework to study and aced every test (I'm no genius). He doesn't try to trick you or fail you in college algebra. Practice and you should pass.

Go to class because he's VERY picky on how you show work on your tests. Only grades in this class are the tests. Hw is online, but only there for practice. Do that homework and go to class and you'll ace this class.

He is a great professor! Make sure to go to EVERY class lecture and DO THE HOMEWORK!!!! If you do these two things you will definitely ace this class. He Is very helpful and will stay on a topic until you understand it.

very tough grader on tests, but his lecutures are very clear. there is no way to pass his class if you dont sit down and do problems yourself. home work is not mandatory.

I am very good at math and have never been one to study for tests and still receive adequate grades. This instructor made his class much more difficult than necessary. Since I never showed up to class I was unaware that even if you got a question right, if you did not solve a question the way he wanted you to IT WAS AUTOMATICALLY WRONG.

Calculus is hard so people automatically hate the professor. However, this professor is one of the few professors at FIU with NO accent so you can actually understand him. He explains everything very well so it's just up to you to do all the homework. If you do the homework and use that to study, you can get an A guaranteed.

REALLY LOVES MATH.
