Hands down the best professor I have ever had. Very Helpful and literally has office hours on every day of the week. Genuinely wants his students to do well in his class. Even thought the labs and the homework can be tedious at times , going to office hours will help you you sort out any difficulties you have. I would recommend everyone to take his class for the LS series. If you attend Jukka's review sessions then you you are all set for the exams

All I want to say is that if you have taken Calc and did well in it, really consider not taking this class. You might be under-challenged. I was convinced to take it by a friend who was premed who told me my GPA >>> Challenging myself. Not true at all imho.

I understand that many people, including my friends, had a completely different experience than me in the class. We all agree that Jukka was a real G. Professor Flippy was amazing as well: he was a great teacher who made the class 100x better with his presence. Jukka was almost as good, which is still saying a lot.

I regret taking this class because:
a) I was bored with the material
b) The lab / coding is really just busy work and I hated it

I liked taking this class because:
a) I loved all my classmates, they were really vibrant and fun people
b) the prof is iconic

Some people had a great time, others didn't, and for various reasons. It was fun sometimes, but towards the end it was really a slog :\

Jukka is an amazing person. He has a suggestion box where you can make suggestions, and he listens to them. I found this class really easy. It can be confusing because they're trying to teach calculus without using calculus terminology for the first few weeks but just run with it. There is a lab portion of this class where you code. Prior to this class, I already knew how to code, so I could complete the lab halfway through class. However, for my friends who didn't know how to code, the lab portion took them forever to complete. Tests are super easy. He gives you his exam from last year, and the actual test ends up being exactly like the practice test. If you ever have a chance to take a class with Jukka, take that opportunity.

I have never met such an amazing professor or instructor until I was taught by Jukka. With this said, I do not find any weaknesses of his teaching or of him in general. I can only speak for his strengths. Jukka is an engaging professor, prioritizes his students, and will always listen to students' feedback in which he will make changes in regards to them. With his passion for teaching, it is clear that he wants his students to not only excel in the course but in the future of the LS30 series as well. Here is a basic outline of his course:

Lectures:
Engaging. In fact, he lectures so well that you do not even want to miss his lectures because it would make you feel as though you just missed a vital part of your life (seriously). His lectures are often times humorous even if it is not intended to be. He explains his material in depth, and if you do not understand a concept at first, you will definitely understand it by your midterm and final because of the immense amount of review sessions and office hours he holds for his students. Clickers are mandatory in this class for your grade (as for any LS course), but you can miss a couple of them and still get full credit (they are credited by participation, not correctness). You'll also fall in love with Flippy and Puffers!

Office Hours:
During my year, Jukka offered countless hours of office hours. He had one one-hour office hour session every single day (and three on Thursdays) just so his students could feel well prepared with the course material. I HIGHLY recommend attending his office hours because he goes over homework problems and helps you understand the concepts exceptionally well.

Homework:
Homework is time-consuming for this course. Plan your time accordingly. This is where you can utilize office hours to get additional help on homework. You can also work with peers or go to your TA's office hours too. Since the textbook is solely made for the UCLA LS30 course, you cannot find "answers" online, so it is something you would have to figure out yourself. Definitely read the paragraphs before and after the homework questions because sometimes the answers are located there! Homework is based on correctness (full 2 points per problem if you are headed in the right direction/your answer is correct, 1 point if you are somewhat heading in the right direction but not there yet, and 0 points if you are completely lost/wrong).

Labs:
Labs for this course are definitely difficult especially as you progress throughout the quarter. It is a good idea to pay attention to the fundamentals because they build upon each other until you have to utilize all of your skills as you get to the labs later on in the quarter. However, all LS30A courses complete the same labs, so it is not something you can avoid by choosing a different professor. You can only hope that your TA is great and can help you sufficiently during your 1 hour and 50 minute lab session. Nevertheless, you can always attend their office hours for additional help.

Midterm/Final:
Jukka prepares you incredibly well for these exams, so there is nothing you should worry about. He provides 4 practice exams before every exam from previous professors/years (he even provides his previous exam from a year or two before!) He holds multiple two-hour review sessions before these major exams to go over any practice problems from those practice exams or to go over any questions you have in general about the material. Trust me when I say that you will be prepared because I definitely felt over-prepared for all of his exams. As a heads up, his exams resemble his practice exams almost exactly!

Suggestion Box:
Jukka LISTENS to you. I would not be surprised if he received a lot of praise in his suggestion box my year because every student LOVED him. The suggestions are anonymous, and Jukka reads every single one of them. For my year, he dropped or altered the grading for so many assignments based on what students suggested. I felt as though he gave his students too much flexibility and privilege in the course because he would alter/drop so many different assignments simply because students thought it was "hard." Nevertheless, he would always find ways to help his students succeed in the class.

Overall, Jukka is one of those professors who sleeps less than his students to give his students the best experience in his course, which shows how much he cares. You can see him sending emails out at 4 AM in the morning reassuring his students as we all freak out over something. Jukka sends out emails constantly, but each email is so important, so please read them! He deserves so much for all he has done and does not receive enough credit for his hard work. If you are able to be one of his students, I can definitely say that you are lucky because you will be in good hands. Utilize all he has to give (because there is SO much), and I guarantee that you will 100% succeed.

Very easy class. Didn't pay attention, only went to class for clickers. The only part that is a bit difficult are the labs which can be tedious at times. The professor is very kind, even setting up individual appointments with students after the midterm to discuss ways to help students improve.

I would 10000000% recommend Jukka!! The class is insanely easy because he is an excellent teacher! The content is very easy and he is extremely concerned about student learning. You will learn a lot from this class. The coding portion isn't that bad, so don't be too scared. You get plenty of practice problems before exams which allows you to prepare yourself. There are hardly any curveballs in the class. He truly tests you on content that has been covered. Overall, take this class with Jukka if you can!!!
Also, I am selling my textbook! email me at ************* if interested!

amazing professor who really cares about the learning of his students

I had never taken calculus before this class but that didn't seem to affect my understanding much. Jukka is a very interesting guy who genuinely cares about his students. He holds office hours and review sessions to help prepare students for the exams but the content of this class can be pretty confusing. I also hate coding which was a downside but my TA, John, was very helpful and funny. I would recommend taking this class with Jukka if you have to take the class because the content will be similar among all professors but Jukka tries to help students succeed in the class.

This class was very very easy. Jukka's lectures are very interesting and engaging. He often tells jokes and finds places to slide in sarcasm, making lecture very fun. He gives a fair amount of homework and has clicker questions nearly every lecture (aka attendance is important). In terms of midterms and finals, they are very straightforward. If you utilize the materials/practice problems he provides, you should be well prepared. Additionally, you should attend the review sessions he holds before big exams because he gives a lot of useful information about what WILL be on the exam. The only thing that most people struggle with in this course is the lab section. Personally, I didn't struggle much. However, if you find yourself struggling with this class, you can always go to office hours/ ask your TA/LA. They are very helpful. Since this class has a lab exam portion, it is important to truly learn how to do the code. Overall, this class was probably my favorite class of my fall quarter. Choose Jukka if possible!

The book for this class is honestly shit. The LS 30 series is fairly new but the book is often unclear and has a lot of typos. Labs were pretty annoying but once you get the handle of coding the lab exam is easy and it becomes free points. Jukka is honestly such a G. I was a bit bored in lectures at times but Jukka is a really awesome guy. He cares about his students and wants everyone to succeed and get an A. He said he understood the book was bad and even asked for our feedback in improving the course for the future. He also gave us midterm and final exams to help us study. The midterm was way harder than the final. Jukka gave us his previous year's final to study for and the questions were literally the same except for a few changes that helped make the questions clearer and easier. I didn't always understand the concepts Jukka was talking about in lecture and I stopped reading the book at some point. But make sure to go to review sessions he goes over everything you would need for the exams. Jukka's the best.
