Best professor anyone will ever take at UCLA, hands down. I seriously don't think you'll meet a better professor than Jukka Keranen. Whether it's for your major or you want to just experience how much of a god Jukka is, I seriously recommend taking him. Fair grading, fair tests, abundant opportunities, he's got the whole package covered. The COVID-19 pandemic didn't even stop him from being a complete god and an absolute stud. Again, it's just a great experience to take a class with him, so make sure to take him while your here at UCLA!

Jukka is really nice and a good lecturer. Lots of easy points (labs, quizzes, etc.) to pad your grade. I had no idea what I was doing most of the time but still managed an A- so you can too. HIGHLY recommend you get a course hero because homework is long, difficult and based on completion. Homework was probably the most difficult aspect of this course.

If you have the option, please do yourself a favor and take this class with Jukka. Ucla is luckly to have him, he genuinely cares about all of his students, and is basically everything good in the world. And if you go to lectures, office hours, and do all the homework, you'll get an A no problem.

Jukka is probably one of the best teachers I've ever had. His explanations are very clear and the way he formats his class so that we spend half the lecture reviewing old content and the second half going over new content is really helpful because it helps consolidate what you learn. I really appreciate how he gives us multiple attempts on quizzes and sometimes extends the homework deadline to help our grade. He also gives us multiple parts for the midterm and final, like a group test and study guide so that it won't affect our grades as drastically. The content of his class isn't too difficult but sometimes homework assignments can be a bit long. As long as you watch his office hour recordings and work on it early, though, it's very manageable. Flippy and Puffers are also very adorable.

Jukka is an absolute legend. I am absolutely gobsmacked as to how well Jukka ran his class. Jukka will take a bullet for you. Jukka would give you the shirt off his back. Jukka is extremely accommodating and takes suggestions very readily. It's been only a few weeks from the last time I was in his class, but I already miss it. If you can take Jukka's class, take it. Absolutely take it. There is not a lick of regret you will experience because it is almost impossible to get a bad grade with the amount of free points and buffer points on the exams he gives you. In fact, I've grown to respect Jukka so deeply that not only have I prepared an acrostic in his honor, but I will also be getting a tattoo of his face on my forehead and will be naming my firstborn Jukka Keranen.

To Jukka:
Just take his class
U will love him
King
Knows the difference between mathematical calculus and a renal calculus
Absolutely splendid

Jukka Keranen is god.

Jukka is hands down the best professor I have experienced at UCLA. Since this is a required class and most of you have to take it, absolutely 100% take it with him. He is so nice and considering to his students.

Jukka is king. I'm actually convinced I would have flunked without him. But he is the coolest dude, by far. Funny too.
Class structure is basically weekly homework, weekly lab, weekly quiz and the participation quizzes. He drops your lowest score for all of those, and you get infinite participation quiz tries. Weekly homework is worth doing just for the practice, especially if you are me and math hurts you. Weekly labs are pretty easy honestly, although I will note I had some python (and java) experience coming into this. But even without that you work in a group that can help you out. Weekly quizzes are doable if you attend/pay attention to lectures, and you get two tries (score is averaged between them).
Exam structure is actually whack but super generous. There's 3 stages. The first stage is literally just making a study guide with your group, and that's 30%. It's free points as long as you follow the instructions. Stage 2 is 40%, and it's an individual section. Make sure to check your work, and doing the practice exam questions he provides is the best way to study for it. Make sure you actually understand them. Stage 3 is group exam with your study guide group. Similar questions to the exam, and with 4 people working on it together you should probably do alright. It's a weird system but allows you to effectively bomb the individual portion (I did!) and still do fine (I did!). Additionally, he'll often offer point make-up opportunities for questions the class as a whole does bad on. So it's pretty fair, in my opinion.

I am not a math person. I did good anyways, and would have done better if I hadn't just stopped paying attention after the midterm. That was entirely a me problem. Jukka is a god among professors and has an amazing grading scheme and also I would trust him with my life. Definitely do the homework and the practice exam questions and make sure you actually understand them and double check your work. You should be okay,

Professor Jukka was a great instructor. He was always enthusiastic and would take the time to answer several questions during lecture with clear explanations. When he sensed that a good amount of the class was struggling with a concept, he would make sure to review it for a bit before getting into the rest of that day's lesson. The coding aspect of the class honestly wasn't as terrible as I thought it would be (just time consuming). Sometimes the workload was a but much, but it never really felt like useless busy work. Coming from someone who was very much lacking confidence in their math skills after high school, this class was enjoyable.
