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 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.

Professor Jukka is the GOAT. He's so generous. Obviously, you're here to find out how you can do well on the midterms and final, right? My suggestion is to just practice the practice midterms/finals that he gives. Be diligent and do homework, because test questions can also be taken from the Further Exercises sections on the homework, so they do genuinely prepare you for the large assessments. Ultimately, just have fun and relax. Don't stress out too much - rest assured that Jukka isn't just one of the good ones, he's one of the great ones. It's not every quarter you get a professor like Jukka.

Jukka is the absolute goat. He tests us on exactly what he teaches, which is how it should be. He gives ample extra credit and is lenient on extensions which reduced my stress a lot throughout the quarter. He made taking this class over Zoom fun and I absolutely loved this class. He structures the midterms and final in a way where he prizes learning over cramming for a letter grade and this helped my understanding so much. For my coding section, Zach was my TA and he was amazing, super funny and nice. All in all, 11/10 experience please take this class!

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 amazing! He is so sweet and lenient, especially with school being online. It's so easy to end with an A, he gives everyone 20 points extra credit so your grade is already boosted. Work can pile up if you let the recorded lectures stack up, and the homework is pretty lengthy. Jukka takes so much time to make sure we all understand and is happy to give any extension you need. Definitely take this class!

THIS PROFESSOR is a legend to say the least. Not only does he put in an insane amount of time for his office hours, social hours, and midterm/final review sessions but he is also willing to schedule 1 on 1 appointments with his students to really help them succeed. His lectures are super entertaining (especially with his own helpers: Flippy and Puffers) with engaging participation quizzes that really help you grasp the material. Learning how to code may be a little challenging at times, but it really pays off and really satisfying once you get a hang of it. Although there is a bit of homework, it is all reasonable and really helps you grasp the concepts of the course. His midterm and final are split in 3 sections: study guide, test, and group test. This is super helpful for those who might not be the best test-takers and allows you a second chance if you do bomb the test. Last but not least, this man drives a Porsche 911 and has two PhDs.

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.

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.
