Love Jukka! He is such a great professor. Has a very different style of teaching and I personally enjoyed his lectures because of this style of teaching. The textbook that we use is essentially free and the homework load isn't bad at all. Great class. He really wants his students to do well. Lab was interesting - it seemed relatively useless in 30A, but it is the foundation of lab for 30B which is a lot more useful in my opinion.

I LOVE Jukka, and 10/10 would recommend him to anyone. For tests just study his past exams and the materials he gives you and the midterm and final will be nearly identical to those. Flippy and Puffers are my favs, so just a shout out to them.

If you're confused about anything his office hours are usually helpful, pay attention during class, and do the homework and you'll be fine. Definitely a pretty easy math class and if you have the chance to take this series I would. The coding is a little hard at first, but my TA's were always really helpful if I ever got confused, make friends in your lab section and that helps too. Daniel and Michael were my TA's for 30A and B and they were both great.

Best professor ever.

The most quirky professor ever, my favorite of freshman year. He is extremely receptive to student feedback in his anonymous suggestion box. He holds 4 office hours a week where he helps you with homework, and his midterms and finals are not difficult at all as long as you complete his review materials (even if you don't pay attention in class).

Jukka is one of the best professors in the LS department. He really cares about his students and cares if they understand the material or not. He is very understanding and will listen to student's comments/complaints. He is an actual educator, unlike many professors here on campus. Definitely take his class if given the chance!!!

Jukka was an amazing professor. He really cares about his students. Make sure you go to his office hours, he has a bunch. He prepares you really well for exams, don't be afraid.

The class material was incredibly boring but wow did Jukka make this class tolerable. Jukka was an incredible professor. He's funny, nice, and truly cares about seeing his students succeeding and understanding the material. His office hours are so so helpful. In office hours, he goes over everything you're struggling with in the homework and the practice exam materials he gives. He has a suggestion box on CCLE where you can put in your suggestions and comments about the class and he actually takes each of those comments into consideration and applies them. His lectures help a lot with understanding the material because it's so abstract so you want to be going to lecture (also there are clicker questions so). The homework was pretty lengthy honestly but I really won't complain about it because the TAs, LAs, and Jukka were all really helpful with it (I woke up early on the days they were due and spent like the entire morning until lecture in the afternoon on them, including going to TA office hours). The textbook was sometimes unclear and had mistakes but Jukka would bring them up and fix them. My TA graded pretty hard on the homeworks but the lowest 2 homework scores were dropped so it wasn't a big deal. The hardest part about the class was definitely the labs but going to TA office hours for those also really helped. I didn't like how my TA set up his office hours so I just went to other TAs and loved theirs. The labs were also graded really leniently and after our suggestions, Jukka dropped our lowest lab grade as well. We were also supposed to have a lab exam but he made it into a significant amount of extra credit and distributed the weight of the exam to other components. He also has two grading schemes and automatically chooses the better one for your grade which is nice. The exams were also not difficult. Jukka gives a whole bunch of practice exams (which are past exams from other professors and one from himself) and holds two review sessions for each lecture (definitely recommend going to the primary review sessions,,,the secondary ones are more we ask questions, he answers). He pulls questions straight from his old exams so PLEASE do them. You definitely feel prepared for the exams and they also don't grade really hard on them either. I got an A- on the midterm with like 7 hours of studying and an A+ on the final with my only studying being doing the old practice final he gave us. I highly recommend this class and Jukka as a professor. If you took calculus in high school, the actual math in this class is really easy and even if you didn't, it still is not hard at all.

Jukka is honestly one of the best professors I have had so far. He makes sure you're prepared for the midterm and the final, by literally holding review sessions that are pretty much the exact same things that will be on the tests. He literally uses past exam questions on the test! He holds so many office hours and just really wants you to succeed. The homework for this class isn't that bad and is honestly given to help you prepare. He also lectures really well and understanding the content isn't too bad. He genuinely cares about students and wants you to do well and offers you so many resources to do well. The labs are probably one of the harder things about this class but it isn't too bad given that you can get help.

If you get the opportunity to take Jukka's class, TAKE IT!! Jukka is the ABSOLUTE BEST. what a guy honestly. He has these two stuffed animals named Flippy and Puffers, and he puts them on the table and has the class say hello to them every lecture and it warms my heart every freaking time. He really sets you up for success. He tells you EXACTLY what to study for the midterm and final. and when I say exactly, I mean EXACTLY. Lectures are mandatory because of clicker points, but I would have gone even if they weren't because he's so funny and the slides are very helpful.

As far as labs go, the coding was kinda weird because we'd never really talk about the coding in lecture, so lecture and lab felt very disconnected. I had never coded before, but let me assure you that it's VERY DOABLE. You finish a pretty good chunk of the weekly coding labs during the lab itself, and Jukka canceled the lab final because he is a freaking g. He has this online anonymous suggestion box , and he is very good about addressing student concerns.

The math itself is MUCH easier than calc bc!! and it felt more practical too. I'm very happy I choose 30a over the other series, and I'm even happier I got Jukka because this dude is SO GOOD. The whole class absolutely LOVED him. I cannot praise him enough. Can't wait to have him again for 30b.

Jukka is a very considerate human being and has sympathy for us freshmen. He listens to his student's advice and never screws us over. The class itself is a mixture of basic calculus, modeling, the concept of equilibrium, and introductory operation of SageMath. Homework problems can be a little overwhelming in terms of quantity, but Jukka has made adjustments such as due date extension and truncating the number of problems assigned. The lab portion, where you learn about how to incorporate concepts into the Python-based program SageMath, can be tedious at first. But it's not that intimidating after all since you're allowed to collaborate. You should definitely go to the review sessions Jukka offered right before midterm and final exams; those are extremely helpful and will clarify every single confusion you may have. Absolutely recommend.
