If you need to take this class please take it with Jukka. He is by far one of the best profs I've had at UCLA and he is someone who truly cares about his students and wants them to succeed. He's very entertaining and kind; I was having a mental health crisis in the beginning of the quarter and he was very gracious with extending my deadlines. He also offerred extra credit for our midterms because of our class performance, and allowed us to drop one midterm if needed. The grading scale was either 1. midterm 1, midterm 2, final, or 2. midterm, HW, final. So make sure to do all of your homework because you might need to drop one midterm. He put in the extra work and more to make sure we were prepared for the exams and he made me enjoy math again. There were in class clickers, weekly homework, weekly in discussion quizzes, 2 midterms, and 1 final.

If Jukka needed a kidney, I would sacrifice mine for him. If you took calc AB in high school this class should be doable. The homework is an absolute pain in the ass. He gives 30-50 homework problems a week and although they are graded on completion, I've gotten points off because I bs the answers a little to much. The syllabus says "a decent attempt needs to be made on the homework for full points" Grading scheme is 35% final, best 2 of 3, 20% midterm1/ 20% midterm2/ 20% homework, 5% participation and 20% discussion quizzes (lowest 2 are dropped), so you can still get 100% in the class if you didn't do any homework or if you got 0% on a midterm. The midterms are very fair and super similar to the practice midterm he gives, so its in your best interest to do them. He gives you all the materials you need to do well on the midterm and final (list of homework questions) but its literally so much I didn't bother looking at them and just focused on the practice midterm instead. Weekly quizzes should be free points because you have 72 hours to think about your answers if you have your discussion on Tuesday since the answers aren't due until Thursday, so make sure you have your discussion on Tuesday. As a lecturer, Jukka is not the best since he is naturally good at math (his undergrad is from Princeton and Masters is from Cambridge) and has a philosophy background. He explains things in a very theoretical way which is not the most useful for basic calc. You're going to have to watch organic chemistry tutor to brush up on some topics even if you took it in high school. Also he gave us a chance to get back full points on our lowest scoring problem on midterm1, but only because the average was low (68%). Jukka won't fail you, but the class is not a free A. Just make sure you study well in advance for the midterm and final and go to the review sessions.

Hes great, the other reviews go in depth so I dont have much to say except take his classes :).

TAKE HIM!!! Jukka is by far one of the best professors at UCLA. He genuinely cares for his students and offered so much material that helped. I had never had any previous calculus experience, and while sometimes the lectures confused me, him posting the slides and assigning relevant problems in the worksheet and homework really helped me get a good understanding. Also he is SO HELPFUL with getting your grade up, the homework replaced one of our midterm scores and he gave us extra credit on a midterm that he had to grade himself despite him already having this curve in place. There were so many office hours and he would always be willing to work through problems with students. I cannot stress enough how amazing he is, some may complain about the workload, but since the homework replaces the midterm, I believe doing all those problems is extremely well worth it. Overall, totally take him if you can!!!

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.
