As someone who absolutely hated LS30B, Jukka totally redeemed this series for me. Other than the coding, which I will never like, I grew to like this class. Jukka is so fair and he gives out accurate practice tests. He knows what topics are difficult and spends extra time on them. He’s quirky but really a sweet funny guy, and I’ll miss his teaching!

Jukka's class was fairly easy. He only tests you on what he has taught you. Be sure to attend his office hours and do the practice problems he gives out before the midterm and final. These are very useful because they are quite similar to the exams themselves. Sometimes I found that his teaching style was unclear, so I just watched YouTube videos or looked back over his slides to review what he had said in class. If you put in the time to understand what he is teaching and can solve all the different types of problems he discusses in class, then you will do fine.

(Lastly, Jukka has a dry, sarcastic sense of humor and can seem a bit condescending, but he is actually a nice and funny guy. )

I took LIFESCI 30B with Jukka during Winter 2019.

Chances are that if you're looking at Bruinwalk for LS30B, you're probably required to take this class as a major prerequisite anyway and you're probably just comparing professors.

That being said, I was very happy to have Jukka as my professor for the LS 30 series. Although I do admit I often got bored during the lecture slides, they were effective in helping me learn the material. And although I spent many hours doing the assigned homework problems, they helped me become proficient at the material.

Jukka was also very helpful during his office hours and review sessions. He went over problems in great detail and it was obvious he cared a lot for his students' success.

The midterm and final study guides and practice templates prepare you extremely well. For the 30A midterm and final and the 30B midterm, Jukka was very straight forward--I did pretty well because he was clear about exactly what to study. The 30B final was slightly trickier but I still did pretty well.

Juuka Keranen is easily the best professor I've had at UCLA so far. He clearly cares for his students in a way that goes beyond just teaching. He's incredibly kind, approachable, and funny. In terms of the class itself, the material was slightly more challenging than that of LS30A, but it's definitely manageable and easy to understand if you put in the work. The midterm was straightforward and modeled after the study material he provides, so there should be no surprises there. Labs (coding), are still as annoying as they were in LS30A but they aren't graded hard and are a small part of your grade, and there's no lab exam! As the class reached the second half the material definitely became more conceptual but as long as you go to class, read the lecture slides, and pay attention to clicker questions, you'll be fine. If not, go to his office hours, they help a lot in understanding the material and going over homework problems. Juuka's teaching style is a bit formal and may sometimes confuse some with its notation but trust me, it's very very doable. The textbook wasn't as helpful in understanding the course as the lecture slides were. I didn't know what was going on in the class until 3 days before the final, but I just went over his lecture slides, attended his (amazing) review sessions and study material and came out with an A+. Take Juuka for LS30B if you want to learn, have a fun time, and get a good grade in a math class.

Jukka is a great professor and he knows the material well. He is very clear in the lectures and all of the slides are available on CCLE if you miss anything. Doing well is this class isn't rocket science; basically just do the labs and the homework and go to his review sessions before the midterm and the final. When I took this class the final was significantly harder than the midterm so be prepared for that. Class still wasn't too difficult, though. He's a funny guy and will take the time to make sure you understand something is you don't get it the first time around.
