An amazing and kind professor that I am honored to have taken class with! Do yourself a favor an take his class. I promise you will not find a more passionate professor...

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.

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.

Keranen is the best! He truly cares a lot about his students and gives out study guides before the midterm and final, which help a lot in knowing what kind of problems or concepts will be predominant on them.The grade distribution is: 5% Clicker, 13% Homework, 12% Labs, either 25% Midterm and 45% Final or 15% Midterm and 55% Final (whichever is more advantageous towards you). Even though the content may not seem easy, Keranen makes it easier to understand even the most abstract of concepts. Not to mention, he always says funny little things during lecture, which make it fun to go to, and helps make lectures seem to go faster. I would love to take this class again and I hope you all get the chance to take this wonderful class with JUKKA!

Jukka is awesome. I had a hard time in this class because I suck at math and it is a LOT of work and a LOT of math. His office hours are always packed but he is still super helpful. His lectures are fun and he is a total character, you will learn a lot in this class. I had a hard time because I got a concussion midquarter, however, Jukka offered me an incomplete in the class so that I could study more for the final and not stress during the quarter. Seriously such a sweet professor and super accommodating. The class itself is a lot of work, as could be expected in an LS course, but that's not his fault and he really does a great job of making the content fun and interesting. All my homies take LS30 classes with Jukka, be like my homies, you'll be glad you if you take this with him too.

I felt that this may have been some of the most meaningful math I had ever learned. On top of that, Jukka is one of the best professors on campus, and he genuinely cares about how his students do. You have to work hard in this class, but he is quite understanding of different situations. He is also quite funny! If you are going to take LS30B, make sure to take it with Jukka.

LS30A with Jukka was a great experience. He cracks jokes in class and is a very chill professor overall. The workload is okay, although sometimes the homework can get a little tedious but it's still very doable.

My TA was Hannah, and she was AMAZING!! She's a new TA this year but she's so nice and understanding and super helpful for all lab and class related things. She's also just a really fun person to talk to! If you get Hannah as your TA you will love this class 100%.

You've probably already heard many great things about Jukka. He is a legend. periodt.

You've probably already heard many great things about Jukka. But my favorite thing about this class is his suggestion box on CCLE. You will probably never find another professor who cares as deeply about their students' feedback as Jukka does. He is a legend. Periodt.

This was hands down the best possible professor I could have gotten for my first quarter at UCLA. Not only was he funny, engaging, kind, and understanding, the material he taught was also interesting! The class itself requires a fair amount of work, but a lot of it is easy if you just put in the time to understand what is going on. More than that, if you feel like you need more help, or aren't happy with your grades, Jukka is more than willing to talk to you about it and work with your needs. Overall I would recommend that anyone take this class and see for yourself how awesome Jukka is.
