I'm a math major and I studied my tail off for this class. Despite having the solutions to the various problem times hardwired, I was not able to finish any of the exams due to lack of time. I thought the curve would save me, but as previously mentioned, the class is *not curved* so I did worse than expected. Lectures are fast, but useful.

Professor Dos Reis is very friendly and generally teaches well. Does a lot of examples to show you each and every way to approach the solution. She's always happy to stop and answer any questions you have. Occasionally jumps around while explaining concepts, just pay attention and you won't be too lost. Assigns very reasonable amounts of homework.

I thought her lectures were really bad and I just ended up doing all of the work on my own. The class isn't very hard in my opinion, you just have to be willing to put in the work. If you usually struggle in math, definitely take another section if you can.

Very nice and helpful in office hours but lectures are completely terrible. She is always 5-10 mins late to lectures, frequently gets lost in her own example problems. Going to lecture is a waste of time. Exams are not terrible but make up 90% of grade. Webassign homework is not very relevant to class problems. Avoid if you can't learn on your own.

She's funny, engaging, and understandable. For me, her answers to questions were really helpful to build mathematical insight. The class was memorization and formula heavy, but I think differential equations as a subject tends to be a bit "hand-wavy" so I don't think that was a fault on her part. You need to do extra reading to solidify concepts.

Good professor at analysis course, especially in comparison with other professors. She has a heavy french accent, especially on the word thereom, but except that, she did great at lecturing and proving the theorems. But her exams are the hardest, and made up nearly 80% of all the points you can get for this course.

Her lectures for 207 is pretty comprehensive and easy to follow. Apart from her strong french accent that can be hard to understand, she was able to explain the process and concepts well and clarifies people's questions effectively. Sometimes she comes late to the lectures which for a 50 minute lecture it can affect how much we learn by a lot.

Prof Dos Reis is legitimately such an engaging lecturer. She's so funny and really tries to make difficult concepts relatable to students. As a disclaimer, I did not take this class for credit, which is probably why I have such a positive view of real analysis.

Dos Reis is an atrocious lecturer. She talks at light speed with a heavy french accent. She doesn't explain concepts well and her examples usually aren't of a comparable difficulty to what's on the homework or exams. I eventually just stopped going to her lectures and instead went to the section before mine.

Dos Reis spends the entire lecture doing two practice problems and explaining zero concepts which was incredibly unhelpful to my learning. I had to learn all the material on my own (textbook is great). Do not take her if you have never taken a calc class, you will be completely lost.

I honestly do not like dos reis so much so that I stopped going to her lectures and started to go to the lecture before mine (Prof Sanmarco). Even though I took Calc in high school, the way she taught made me forget everything I knew... I got better grades skipping and studying by myself than attending her lectures
