He is very caring and nice. Highly recommended to go to his office hour. The grading is lenient.

Zero feedback. Homeworks are hard as hell. One test at the end, hardest thing in the world. Clearly Mihai is a superb researcher, as evidenced by his papers and papers of others who mention him. Putinar is truly a legend, but definitely not one you would want to take a class with.

Can't teach but expects you to learn through verbal abuse.

He clearly thinks he is teaching graduates.

I can't find any relation between the homework and his lecture. The lecture is super unclear, at least for me. Why can't he think about the reason that students stop asking questions even when the course content goes harder? This is a pure self-study course and the textbook is nearly the worst one I've ever seen.

I really don't know how this old man earned such a high score on RMP. Lecture is deduction heavy with few examples related to homework and exam. He seems to be teaching in an old school way. He has serious accent. His homework problems can't be found online, so be prepared to meditate for a long time for an answer

The guy looks down on student. He does not like teaching and think he smarter than everyone on earth.

I don't know why so many people hate him. As for upper-division class, he is really great and respected. Even though his homework is a little hard sometimes, you will do really well on exams if you read the book. Highly recommend!!

Holy crap. Ease of homework is deceiving. Homework has no inclination of what you need to know for the exams. Midterm had nothing to do with the homework assignments or lectures. Stay away from this jerk if possible.

Professor Putinar is an amazing lecturer. His exams were fair and as someone who really enjoys mathematics, I found his course to be motivating and inspirational. I can't wait to learn more analysis & I appreciate him!! Also head to office hours if you are able to, they help!

Couldn't focus during his lectures. He's not very amusing. Had to purchase HW, but I liked the website a lot because it walked you through everything step by step. Test was easier since it was online and open note.

Mr. Putinar is an uninspiring orator, whose lectures inspire little true understanding of the subject matter. Homework, assigned online through pearson was easily completed, and did not deviate far from the assigned course material. Exams were also given online, through pearson, and were the same difficulty of the homework.

Lectures were dull and I did not attend mostly. Uses an online interactive textbook which is actually really useful if you don't mind self studying, but it's expensive. Light homework and straightforward tests

Lectures were very poor and slides were never helpful. Basically worse copies from the textbook. I read the textbook and watched youtube videos to get through this course. On the bright side, the homework was easy and the tests were short and online. Basically exact problems from the homework software.

He does not care about students at all. Horrible handwriting. However, his course is easy. You can get a good score by self studying. Don't waste time attending lectures or seek help from him.

Professor Putinar seems like a sweet man but oh boy, the way he explains the concepts is just horrible. I didn't learn a single thing in this class. On top of everything, it is mandatory to buy a $80+ program which you do your homework on and tests. The TA's are even worse at explaining. Try to avoid this professor at all costs.

This rating probably doesn't count for much. This class was fully online for some reason, so I honestly didn't learn a single thing. 50% of grade was homework, the rest was tests. All online though, and usually 3 attempts for online textbook homework questions. All I know is his writing is terrible, and you won't learn anything from his lectures.

Worst handwriting that I've ever seen, extremely complex explanations, class is mostly self-study if you want to pass. TA's and online tests are this class's saving grace if you absolutely have to take him.

He has some of the worst handwriting I have ever seen but is a very nice and lenient prof. My TA is extremely helpful in answering questions. Personally, I don't go to lectures and do mostly self study. All HW, midterms, and final were online.

Avoid.

Disorganized, horrible handwriting, not-so-helpful lectures. TA sections and CLAS help but are not a must. Nice person but terrible professor, but generous grading policy. Self-study is heavily needed, prepare to spend a lot of extra time to reinforce the material on your own, otherwise, no one could help.

clear intuitive explanations, easy online tests

Extremely confusing and difficult to understand, worst textbook I've ever seen, basically a self-study course. You'd be much better off watching Khanacademy/3blue1brown videos.

This guy uses complicated terminology to explain simple concepts. Its like hes tryna teach a class of math professors instead of a lower div math class. Its not worth your time going to lecture. His lecture slides are word for word of the textbook, so youre better off teaching yourself from the textbook and youtube.
