This is for Math 174E (a bit of a jump up, I know, but it's not listed here.) Jukka is an incredibly entertaining yet informative lecturer. He explains concepts very clearly and has slides that are easy to follow, using intuitive examples to guide understanding of those concepts further. Despite what some people might say, he is extremely approachable and more than fair in his teaching. There was a conflict during our class that I couldn't remember, around the time of one of the midterms- I think it had to do with him having to cancel several office hours before the midterm, as he would be away on a business trip. He actually offered his students individually the choice to take the midterm either on the regularly scheduled day, or the Tuesday after, and would have held extra office hours before the "makeup" to help struggling students. This shows that he is willing to go above and beyond what's expected of him as a professor despite him really not having to do this just for a few missed office hours.

Despite this, the class did have flaws. It is far too easy, with each midterm, and even the FINAL, being extremely similar to the practice midterms (although no answer key was given out). In fact, you could predict half of the final just by looking at the practice midterm questions that were not similar to what you got on the actual thing. Math 174E is supposed to be an "easy" course, but you pretty much didn't even have to put in effort to get an A here. If Jukka made the class a tad bit more challenging while keeping everything else intact, it would have been one of the most valuable classes I've taken at UCLA. But as it stands, it is still a good class with a good professor.

**LS 30 A+B**
Take Jukka! Very cool professor and very helpful. Grading scheme is so helpful. He really wants you to succeed. He listens to his students and shortened the homework when we complained. He literally tells you what types of questions are going to be on the midterms and finals and gives practice questions for each type. He put so much time into his slides.

***LS 30A and LS 30B***
Your overall course grade will be determined by the better of the following two:
1) 5% Clicker + 10% HW + 15% Labs + 25% Midterm + 45% Final Exam
2) 5% Clicker + 10% HW + 15% Labs + 15% Midterm + 55% Final Exam

What other professor actually lowers the homework load by 2/3 because of student reviews?!!!!!! And goes to bat with the LS office for us when the labs are too hard!!!
Definitely take Jukka for the LS math series, his tests are way clearer(and funnier) than any of the other professors and he gives sooooo many practice problems plus makes a study guide that shows exactly how many problems there will be, what order they'll be in, and EXACTLY what skills each one will test.
He makes his own slides and gives actual math examples (which you'll find the textbook extremely lacking in) for all the theories we learn. I've heard his office hours are useful unless there's too many ppl asking very different questions.
Labs can be challenging, especially in LS30B, but that's the LS core's fault, not Keranen's. They involve coding graphs or functions to better understand the systems we're learning. They do help to connect concepts, but the lady making them seemed to forget halfway through the quarter that most people had no prior coding experience. They give you the coding syntax needed for each lab in the beginning of the quarter, but that tapered off until TA's had to share everything and if they didn't you were screwed. This quarter they stuck in a super easy coding basics quiz for 3% of the lab grade, then the rest is 9 labs (1 a week except lab 7 was suuper long and difficult so was due a week later at the last minute) but only the 7 best lab grades count.
My TA for LS30B was Daniel Sun, he was nice but explained pretty slow. During the last quarter, discussion sections were structured 1st going over hard/important problems from last /next homework, then starting the lab with whatever time was left. Each lab takes maybe up to 2 hours to complete depending on prior experience or lab difficulty. Homework is due every Friday and also took around 2 hours.

Very funny professor, always had some good jokes. He really cares about students understanding and does a LOT of extra office hours. His tests are tough but he really tries to give everyone the necessary tools to succeed. By far the best math professor I've had at UCLA.

Jukka was a funny professor who was always there to help his students during office hours. He did give out a lot of homework but it helped for the midterm and final. I’m selling the textbook! Text me at **********
