Being new to USF this semester he didn't always know the answers to administrative questions bc the rules are set by the math department. But he's easy to understand and his lectures are pretty good. He's always willing to answer questions in and outside of class. He posts his lecture notes. He's flexible and extended due dates a few times.

Very nice professor. Good at explaining concepts! He answers questions in class thoroughly and responds to emails quickly. Pauses for questions during the lecture and doesn't go over the concepts too fast. I would take him again.

He's obviously new to USF. I didn't really think he knew how to teach a huge class with 300+ students. He works problems on paper and displays them on a projector then gives clicker points. He gives like 3-4 clickers that are almost irrelevant sometimes. Just take notes on MLP and youll pass, cuz the exams are on MLP anyway. (oh and he moans...)

I do not know why his ratings are so low. Just took him for summer A, he was funny and straightforward. What he said to study is exactly what is on the tests. He was really helpful.

He's really helpful and he seems to genuinely care about how well his students do. The test reviews are similar to the tests, you just have to really practice the review problems in order to do very well on the tests. He gives you a few days to complete the homework and it's a good idea to do them because they help your grade.

Rothstein is an overall good teacher. I had him for precalc and he is very helpful, he tries to make his class fun. He goes slowly enough in class for you to process the information, unlike some professors.

The class is straightforward,Tests are simple and smooth,However,I do not like SmartLab hours. If it is a lab for smart people why do I need to go there 2 hours a week when I could be 2 hours into the History Channel Even Rothstein seems disinterested in the material he needs to teach he is accessible before and after class. He speaks Spanish to

I think people underestimate him because the course is set up so that most of the practice and learning is done online (MyMathLab). You only see him twice a week for lecture and everything else is at the math lab. He drops the 6 lowest quiz & 6 lowest homework. Drops the lowest test grade. Email him & he'll extend the homework if MLP is acting up.

i loved him! i had him for two semesters and he explains everything. if you don't understand something he will stay after class and help you as well as office hours. he gives practice test and if you do them they are extra credit, be sure to do them! they are exactly like the exam and are a huge help when studying! i would take him again.

Dr. Rothstein was an excellent professor! His attempted jokes and sass made the class as interesting as you can make a math class. The lecture was easy to follow, very easy to ask questions during class and after. He posts the notes online as well if you missed something. Attendance is not necessarily mandatory, but he does do clicker questions.

He was one of the best math teachers on the subject from what I've heard except for the teacher that writes the book that we have to use. He goes step b step through everything and he always has a review before the tests. The final is optional and there's online homework every week but overall it's a good class and he's a good teacher.

A lot of homework and quizzes but expect that with any math class. I often left lectures confused but understood it after doing online homework. ALWAYS do the pre tests, they will save you because they are extremely similar to test.

I had him for Engineering Calculus I, and he was amazing. Of course the class is difficult, but he is very good at teaching the material. If you try, you will get the grade you want. His lectures were all i needed for the tests, did not look at the book once. Reasonable with grading, would recommend attending classes. Very helpful professor.

Hes a bit scattered in the first few classes but he is willing to work with you on anything you need. Get to know him so youre not just another face in the crowd and he will make sure to come by and help you out whenever you see him in the smartlab

Took Rothstein for Engineering Calculus 1. He definitely makes you work for the grade, but he gives partial credit. He'll be very particular about what he gives points about, or even if your totally lost, he'll still give you partial credit. He only did quizzes on Tuesdays, but the problems he did in class are closer to the test than webassign.

Dr. Rothstein is a great professor. As long as you attend his lectures and do your homework as well as the pre-tests you will do great in his class! He will go over problems in class before the test so you can gain clarity on what you need to know on issues you are having. I would take him again!

Expect spending time in the smart lab every week, it helps a lot and he is usually in there to help.

Professor Rothstein was an excellent Calc professor! He was clear about his expectations and grading criteria, incredibly understanding of his students, and an effective communicator of the material. He did everything in his power to make sure that you not only understood Calculus, but actually made it enjoyable to learn.

Good professor, works out problems on the projector so you can see all the steps

Such an easy course. Homework and quizzes are online and he drops several homeworks/ quizzes, and one exam. Excellent professor. Very clear about what to expect on exams.

Take this professor if you're looking for an easy math to fill the FKL requirement. 90% of his class is done through the smart lab & clicker questions is a very low percent of your grade so its okay if you miss a couple classes. Plus he drops quizzes, lab attendance, and one test. He does a couple group activities & he says on canvas when those are

Great professor, really helpful during tutoring in the library and office hours. When it comes to math, you have to put the time into it to understand it. Math has never been my strong point, but I put many hours a week into it and I have an A.

Pretty solid teaching style. Gives out lots of extra credit and is available for extra help during his office hours and in the SMARTLAB.

Simply being consistent with attending lectures, studying material and doing homework will yield you a perfect grade. Ivan Rothstein is a decent teacher and College Algebra is straightforward.

He is very kind and truly wants everyone to pass.. He's an amazing dr, extremely helpful and caring with the students.

I took college algebra with him last spring and he was really great. He explains stuff easily and clearly its not hard to get a good grade with him.

He's the first math instructor in a while that I understand well. He's easy to talk to outside of class, the SmartLab helps a lot for practicing/studying, and he drops a lot of grades. If you don't try you will struggle. Show up to class and stay focused, attend smartlabs, ask questions, and you'll do fine.

Im baffled with how he has such a low rating. He is the best math professor I have ever had. He explains everything so clearly. Moreover, he once said, I am always looking for the smallest excuse to extend your homework... he has countlessly extended homework dates for our convenience. I ended up with a 99.52% in his class after 4 exams.

The nicest professor I've ever had! He definitely cares about his students and wants to make sure you're actually learning the material and overall concepts. Due to class times he isn't able to go over everything you'll be tested on, but he definitely tries his best! Very caring and knowledgeable!

This teacher is amazing. He grades fairly and usually takes off grades that you fail in. You can easily pass it if you go to class and go to the smart lab. For every test you take you get an extra credit assignment that can boost your grade by a whole point. Perfect laid back professor for easy going students.

Homework, quizzes, take home midterm, final group presentation. Dr. Rothstein was so nice and really just wanted everyone to do well. If you show up, and put in a good effort on the work, you should get an A for sure. If you skip a lot, and don't try he won't help you out as much. Take him! Interesting class, great professor!

He's a great professor. Take him if you get the chance. You would not regret it.

Professor was understanding and helpful even after I had an accident that would have affected my grade. I took this class in the summer so it went by fast. Lecture based class usually with a lot of students.

Lectures made the content a lot easier to understand than just following the examples on MyLab. Exams were a majority of the grade percentage and there were only three exams. But, he does let you retake the exam once and drops the lowest grades from homework, quizzes, and clickers. You will 100% need the clicker in his class. Overall a great prof.

Overall, it was ok. He's not the best and not the worst. Pretty typical math professor.

Great person but extremely tough class and not exactly the best professor.

Mr. Rothstein was personally invested in my success in his class. Math has always been challenging for me and he made sure to speak with me after each class to ensure I understood the material he went over. He gave me a ton of motivating and encouraging advice as I just wanted to give up. Ive never had a teacher care so much, hes simply amazing.

Considering the huge adjustments, he was sooooo nice and helped us a lot. He has a lot of homework but it helps prepare for exams. I failed the first exam but final replaces lowest and I will be ending up with an A. He always helped and quick to reply. Lectures are a bit long and confusing but exams are straight forward, recommend!!!!!!

Definitely a teacher to become used to. His style is a bit different in terms of lecture. However, if you do the homework through repetition and study enough to do well on some tests, this teacher will definitely help. Great teacher but you do need to do some textbook teaching. (Not way too bad).

There is a LOT of homework, but he is an awesome teacher so it's worth it. He really does want you to pass and he will help you out however he can. He's really funny, really cool, and he broke down calc 3 in a way I've never seen before. Overall he's an awesome guy and I'd definitely take him again if I had another math class.

Get ready to spend hours in the smart lab! Personally, I am fine with teaching myself and learning form homework problems so this class was super easy for me. Whenever I had questions I would ask him in the smart lab and he was super helpful. For the people that need their hands held, this class would be difficult.

He does a really good job of explaining material, and testing you on that material. What I mean is, he does not make the test problems super complicated. He makes the material from this class challenging, while keeping the parts of those problems from previous classes more simple.

Class meetings are not required and were just used for us to ask questions about the content. His recorded lectures were helpful most of the time and he is the most understanding prof i've ever had. If we were struggling or needed anything he'd extend an assignment or help as much as he could. He's a really funny dude as well, I enjoyed the class.

I took professor Rothstein and absolutely loved him. He is really understanding and lets you make up assignments past the due date if you email him. I didn't think the class was super hard and he gave quite a few extra credit opportunities. He also is really quick about responding to emails which is nice because a lot of profs lack that quality!

Professor Rothstein is relaxed and understanding. The tests were not particularly difficult, some problems are long but that is the nature of DE's. There is usually 1 homework per week on Pearson and their problems are hard, but you have infinite attempts. If you can do these honestly, or at least understand them, you will do well on the tests.

Cool teacher, exams and homework is tough but calc 3 in general is tough so theres not an easy solution to that. The homework is 50 questions on webassign and he gives a full week so thats nice. He also grades leniently and drops quizs and homework. Sometimes its hard to follow along as the class gets harder. Overall good choice for a teacher.

Posts vids of teaching the content. Most of your learning will come from MyLab & Mastering. Drops 4 Canvas quizzes, 4 lab quizzes, 4 homeworks, and 1 exam (final is optional if you like your grade). Unlimited attempts on quizzes. Professor is very nice and reviews content in every class, if needed.

Dr Rothstein is very good and talented professor. He recorded lectures and gave us extra credit. Great professor

This professor was awesome! He explains the notes and gives you helpful tips to succeed. You have a lot of homework and spend a lot of time in the SMARTlab, but if you put in the time and effort you can leave with a good grade.

Prof Rothstein was a great professor. To be honest you don't have to go to your classes as long as you do all of the homework and quizzes online. He has given a lot of allowances and drops a lot of work. I really recommend as this prof is strict but very caring and understanding.

Rothstein was very forgiving throughout the semester which I appreciated a lot. His teaching style is hard to follow so I never went to class. There's typically two hws and quizzes every week but they don't take too long. The exam study guides are the most important thing. Study these very well and you will do good on exams and get a good grade.

Didn't really go to class since the smart lab teaches you how to do the work. There was 2 quizzes and 2 homeworks each week but they were easy. He drops your lowest exam grade so you might not even have to take the final. Studying for the exams was easy since the study guide was literally the same questions but different numbers. Would recommend.

Dr. Rothstein is the perfect professor for differential equations. He understands the sometimes tedious nature of the subject and will frequently showcase interesting tricks to simplify problems significantly. His personality and seemingly endless bag of tricks make differential equations a much more enjoyable experience than it would be otherwise.

Very in-depth and thorough lectures.

His class is lecture heavy, but he gives every example that you'll see on the test, and attendance isn't mandatory. He requires you to spend time in the lab for only 6% of the overall grade so you can get help if you need. His review sessions encourage you to ask questions. I normally suck at math, and I got an A-.

Attendance is not mandatory, but going to class helps. He posts the lectures right after class ends. He teaches you well and even does some of the homework questions during class if time permits. He replies to your Canvas messages quickly. He's a good professor!

I had Rothstein for college algebra and he teaches it well. Per the university, you have to spend 2 hours a week in the Smart Lab for a grade, which is the only place you can do quizzes. There are usually 2 quizzes and 2 homework assignments a week, but again, that's just the course. Overall, good professor and easily accessible.

He was a good lecturer, made everything clear and had lots of examples. Gave a lot of extra credit to make sure we wouldn't fail and gave plenty of opportunities to retake previous exams. Made Calc 3 a really good class.

Exceptional professor at USF. The assignments greatly help test preparation. Approachable and caring, always ready to address queries. Despite the complexity of Calc 3, focused efforts yield favorable results. Recommend utilizing online Canvas videos; they cover diverse examples, enhancing understanding.

The class is mostly completed through the SMARTLab and all of the assignments and quizzes are simple and easy to pass. The lectures are good and the notes are very clear. He is very fair and will drop one or two low scores. The subject is easy to understand even if you struggle with math. I highly recommend.

He goes fast. He doesn't teach concepts but directly uses example problems to explain concepts. So it might get confusing. He gives out a lot of extra credit. And the grading criteria is also clear. There is webassign for homework.

Grade is about 90% tests but every test had 10 bonus points, there was an option to get extra credit on past exams, and the last test was online and a free 100%. If you have a 98-100% and show you put in the effort you may be exempt from the final. Calc 3 is hard but as long as he sees you are really trying you should have no problem!

Fast paced class, no cheat sheets so be ready to memorize formulas. His exam reviews are useful but don't just use them to study he likes to mix up his exams.

Dr. Rothstein is amazing! He teaches very well and makes it clear what will be on the tests. He gives some homework, but is very doable and helps study. If you need an extension he will help, and offers grade make ups for bad exams. Overall a great teacher.

Dr Rothstein is amazing. He cares about his students and is very knowledgeable yet humble. He loves his job and you can tell. There are 5 exams with the final (which can replace your worst grade counting double) and the 4th was just an online assignment with 100 attempts each question. There is a LOT of extra credit and helps during office hours.

I had Dr. Rothstein for Calculus III spring of 2024. Dr. Rothstein is humble, caring, and overall a great lecturer. He will always answer a question even if it seems redundant. Mistakes are often made on the board but he always corrects himself in an engaging way. I wish I could have him for Diff EQ and future classes.

He's very passionate, knowledgable and wants his students to become great. Absolutely nothing to worry about if you have him as a professor.

Professor Rothstein's MAC 2313 Calc III course was without a doubt one of the best classes I have taken at this school. Although he is homework-heavy with challenging tests he makes sure his students fully understand the topics he is teaching. If you do poorly on a test but show him you understand the concepts he will get you the points you need.

Given that this is typically a large lecture class, you can't expect him to hold your hand. He always listens to questions during lectures and make sure to attend if you know it's going to be a difficult chapter. There is a decent amount of homework, but lecture notes are always posted after. He tries to keep students involved and participating.

Good class

Ivan's class is awesome, and I recommend him. He will help you understand the material and is available outside class for 4 hours weekly. The practice tests are like the real tests. He also provides study guides to help you prepare. He responded to emails quickly. The class material is hard, but if you do the work, you should be able to get an ‘A'.

Professor Rothstein is a good professor and provides extensive knowledge on Algebra. While some parts of his lesson can get somewhat confusing, its easy to get back on track once he further elaborates. Good teacher, just show up and pay attention.

First off I've been out of school for 6 years. THIS CLASS IS NOT AS HARD AS PEOPLE SAY. If you do the hw, due one week AFTER the lecture its not hard. SL attendance can be replaced by doing well from the quizes which are mandatory in the library. He drops a lot of grades, 4 hws, canvas quizes, quizes, 1 exam. Come to class and ask questions. Simple

This professor is great as someone who usually dislikes large lectures. He never fails to answer a student's question, and is always there to help. Geniunely cares about his students and understands they have a life outside of his class. The SmartLab is the one thing that is hated about this class, but it is what it is.

Attendance is not mandatory for this class but he is a very clear and good professor. He always gives out extra credit before each exam. The material was not difficult and he explains everything very clearly. Overall a very good professor and not difficult coursework.

This class took less effort than my other classes! The course mainly revolves around the SMARTLAB. The best way to pass the class is to attend his lectures and then apply the information to the assignments! Excited to take him during Precalculus.

Professor Rothstein is a caring, humble lecturer who makes Calculus III engaging. While his teaching style can move quickly, he offers plenty of extra credit and exam redemption to help students succeed. Unstuck ai was a lifesaver for reviewing concepts and preparing for tests.

Dr. Rothstein teaches mainly by doing example problems, so writing down notes during lectures helps with reviewing while doing homework. Homework, quizzes, and tests are online, and the SMARTlab is mandatory, but helpful. Dr. Rothstein also makes sure to answer everyone's questions during class and doesn't want anyone to be confused.

The classes were fun and he was good at giving us examples to do together and on our own. The SMARTLab is mandatory and it does take some time for some lessons, but the tests are easier than the practice tests. He is good at explaining the concepts and is very helpful in the SMARTLab. He is funny also.

Ivan is a great professor. His lectures were always easy to understand and he has a sense of humor. He would always be patient with everyone when asking him questions and would always explain to the best of his abilities. The downside is that tests are worth 70% of your grade but he drops your worst test grade at the end of the semester.

He really wants you to succeed. You get a test dropped at the end of the year, you get multiple quizzes and homework grades dropped too. You get two attempts on every test, infinite on quizzes. You get extra credit for doing the test reviews, which are nearly identical to the actual tests, giving you up to 4% extra credit added to your grade.

Very passionate about math and his students. Lots of work, but multiple attempts are given on everything including tests, so there is every opportunity to get an A+, if you fail it is your fault, not Ivan's.

I love the guy, very funny but teaches 15% of each chapter in the lectures so you'll have to spend quite a while at the SmartLab and self-teach for the tests. Practice tests are extra credit and IDENTICAL to the exams. The people that fail this simply didn't put enough effort, answers emails quickly and will explain the work further :)

His lectures aren't mandatory to attend and he posts the notes he does on canvas. You kinda of have to mainly teach yourself everything since his lectures aren't that super helpful sometimes. He's a nice professor though!

The class was non-mandatory(try to go to the SmartLab two hours a week for credit). The SmartLab will tutor you if you struggle. Try to go to class for exam reviews(exactly like the exam) and team activities (graded days). You will be fine as long as you put effort in.

I like this professor, smartly is tedious but allowed me not to procrastinate. He drops a lot of grades and also offers extra credit. There's two attempts for the test which was great. The practice tests are so similar to the exams and the practice exams are extra credit. I would take again. You just have to put in the effort and you will do great.

If you've had strict teachers, he is a very easy teacher to have. He records his lectures and posts his notes; attendance isn't mandatory unless there is a team activity. He's decent; the work is online for the most part.

I would 100% take him again. He is a great professor and you can tell he cares. He was often lenient with extensions, and when asking him a question, he actually taught you instead of making you feel stupid and belittling you. I would say, if you're ready to do the work and study on your time as well, you can definitely succeed in this course.

The class itself is pretty easy, the issue is he doesn't really “teach' the subject he just shows you how to do it. Overall good teacher and chill, you will have to teach yourself 90% of the material but he is always there to help. Smart lab is also great and straightforward. YOU WILL GET AN A IN HIS CLASS IF YOU PUT IN THE WORK , ITS CAKE TRUST!!!

the workload for this class sucks but hes very flexible with due dates and drops a LOT of stuff, my dorm got flooded and i emailed him if i could have an extension and he gave me another week although his handwriting is highkey bad but he does lots of practice problems in class and is just a chill guy

mac1147 is a difficult course, it moves really quickly and builds off of previous chapters. That being said, this professors grading is very fair. He drops a decent amount of assignments and if you show up to class and get familiar with him he wants to help out. This professor cares about your success but you only get back what you put into it.

He's a great professor. Explains things pretty straight foward during his lectures. There were a handful of times where it feels like he just pulls infomation from think air but he is nice and welcoming to answering "dumb questions" so dont be afraid to just ask for help understanding.

Professor Rothstein is very caring, accessible outside of class, and drops a lot of assignments and quizzes. He teaches primarily through examples and it can be difficult to follow. However, if you do the homework, study, and take time to actually learn the material you will be fine. Precalc can be hard but use your resources and put in the work!

the prof himself isn't very good at teaching so I had to teach myself most of the concepts. however, the prof does also drop a ton of low grades as well as give tons of extra credit, so I cant really complain. just be sure to attend class even if you don't feel like going, there's alotta group projects that u might miss. also smartlab helps tons!!!
