Keranen is an amazing professor. He cares about his students' learning and makes his lectures interesting for them. His tests are fair. His grading and format for assignments is fair. Very good professor and makes 30B easy to learn.

Best professor at UCLA!

Best professor you could ever have at UCLA. He is the GOAT. professor Jukka really devote almost all of his time to his students. He explain almost every problem from the homework so you probably will receive full score for the hw. He has very thorough study guide for every tests (eg, he even marks the page number of his lecture slides that you need to know for the exam). He is very very approachable and very helpful professor. You will wish to take him again because I do.

There's a lot I could say about Jukka. You can tell he is extremely fond of and dedicated to mathematics. There are a plethora of ways he shows this. He devotes extra time to student hours, and will even have extra student hours on his weekend break. He allows a flashcard on his tests because his focus is not on memorization, it's on application and understanding. He has policies that ensure that if you put in the work, you will end up with a good grade. For example, he drops the lowest two homework and drops your lowest assessment, be it the homework, midterm 1 or midterm 2. Trust that he will find time for you and your struggles, if you fail his class, all I can say is that it is not his fault.

Jukka is such a UNIQUE individual and his love for mathematics makes it easy to be engaged by his lectures. He is EXTREMELY approachable when it comes to asking questions and he always devotes a ton of time to review sessions and office hours especially right before exams.

As someone who took Calc AB in highschool, the actual course content was entirely review which made it easy to succeed on homeworks and exams, but the actual lectures were of no intellectual value to me specifically. HOWEVER, I still attended every single one as Clicker participation is factored into grades, and of course it didn't hurt to work out problems with my classmates.

As far as workload, Jukka did mention he had gotten complaints about assigning too much work, which is something I did not feel at all taking this class: There were weekly (long-ish) homeworks and worksheets to be completed in discussion, weekly quizzes taken during the first 10 minutes of discussion, and of course, two midterms and a final exam.

I would definitely recommend this class as a great intro to Calc, but even more so, Jukka as a professor in general!
