Reviews of professor Roger Casals

Rating: 5.0/5, difficulty: 2.0/5
professor casals is the best !!! his enthusiasm for teaching and math clearly show in his lectures. super organized, always ready to help, puts in a great deal of effort to make sure you actually learn. his tests are a lot like practice tests. just go to class and do the practice sets and practice tests and you will do well. take him if you can !

PROFESSOR CASALS IS THE BEST PROFESSOR IN THE UC DAVIS MATH DEPARTMENT!!!! He has very organized lectures,very accessible outside of office hours; One time I even stayed for 30 minutes overtime, because I didn't understand a problem. He is also open to feedback, and his midterms are similar to his practice exams.

Professor Casals obviously cares about his students as he genuinely takes the time to answer any and every question during/after lecture. He also re-arranged the way that homework was formatted, based off of a student feedback survey, following MT1. This is my first ever review, but I had to share that this guy is the best.

Take him if you can!! Super accommodating professor. Practice tests were almost identical to the real exams. 2 midterms, drops the lowest score and gave 20 points of extra credit opportunity on each midterm. no extra credit for our final, but it wasn't hard. best math prof I've had so far!!

Casals' lectures for the first part of 21C (continuity, Taylor series) were not understandable: for the first part, I had to attend both his lectures and Alameda's. But, he was wonderful with taking our feedback and implementing it into the second part of the course. 
- receptive to feedback
- valuable lectures
- easy tests
- (initially) hard HW

interesting lectures and he also gives us problem sets after each lecture covering its content which are super helpful with a test pov. tests are fair and very similar to practice tests. honestly just keep up with the problem sets and practice tests and you'll be fine but i recommend going to lectures because he's fr a great lecturer

definitely take him if u can!! originally pretty hw heavy in the beginning of the quarter but he's super accommodating and after the course survey changed to just webwork assignments and optional practice problems. his practice tests are a good reflection of the actual exams. attendance isn't mandatory but go if u can, he's a great lecturer!

Very good lecturer. Tries his hardest to make sure to answer everyone's questions. Always checks for understanding. Gives good examples and step by step demonstration. Very responsive to feedback and adjusts lectures and assignments accordingly. Midterms and final extremely similar to practice tests. Takes highest midterm score only.
