A few days ago, I was in a horrific car crash. At some point, the paramedics told me that my heart stopped beating, and I was considered medically dead for 2 minutes. At some point in my period of unconsciousness, however, something incredible happened. After being in a state of utter and complete blackness for what seemed like an eternity, I suddenly woke up in a bright field with a long staircase in front of me. I walked up the staircase, feeling a pleasant warmth from the radiating sun surround me as I did so. Eventually, I reached giant golden gates at the top of the staircase. That's when the memory of the car crash hit me like a ton of bricks, and I suddenly realized that I had died and I was now at the gates of heaven. However, I wasn't frightened. There was something calming about this place. After waiting a few minutes, I saw a figure slowly walking towards me and the gates. He eventually reached the gates, and without even touching them, he summoned them to open. Something deep inside told me that this figure opening the doors and about to confront me was God. When the gates opened, he stepped forth, and that's when I saw his face. Standing in front of me, in all his godly grandiosity, was Akram Almohalwas. I was frozen with awe. He handed me a chi square table, and told me that the meaning of life can be determined alone from taking his Stats 13 class. At this moment I was certain: Almohalwas himself was God. I reached to touch his beautiful face, but that's when I woke up in the hospital. I will never forget this experience, and my life will never be the same afterwards.

Spring 2018 - This is a review for LS40, the new LS stats class. I would recommend taking it with Guillaume! Obviously you are learning stats, so it is nothing that complex. But rather than learning how to do actual math, you learn about different types of graphs, different types of tests to run, etc. and what occasions to use each. The exams are more like asking, "What type of graph is suitable for this data? What does this distribution say about the data? What type of test should be performed on something with 2 independent variables?" etc. and very little actual calculations . Like the LS30 series, you have to learn how to code, but I found it a lot more easy and fun in this class. Guillaume made the homework fun, by doing things like having you perform statistics to solve a murder mystery. And if you are having trouble you can always go to one of the TA's office hours to make sure you get full credit. Both the midterm and the final exam were open note, he let us print as much notes as we wanted. Hilariously, he had a crossword puzzle on the midterm, and a word search on the final. I would say the class is completely doable and possible to get an A, don't slack off too much since it's stats, but make sure to understand the different types of graphs, tests, etc. Btw, he is a pretty good looking man with a French accent for all the girls/guys out there into that ;)

Summer 2021 - Professor Chen was super clear and helpful the entire 5 weeks of this class. You're definitely missing out if you don't take this class with him! He's pretty funny, very engaging during lecture, and incredibly passionate when it comes to teaching stats. Quizzes and the final were definitely fair and were often slightly more difficult than the homework problems assigned (when it came to conceptual questions which came up pretty often). Professor Chen also gives out solutions to most of the homework problems assigned which is great since some of them can be very tricky. My TA for the labs walked us through the coding in discussion which also eased our workload by quite a bit. Overall, this class was pretty chill and if you have the chance, definitely take other classes with Professor Chen!

Fall 2020 - I loved taking Stats 13 with Professor Gould! There's some busy work with this class (weekly homework assignments and coding labs), but it's fairly straightforward and relatively easy for a five unit class. He posts videos going over all of the textbook concepts before lecture so the structure of the class is really helpful for learning the material (especially for slow readers like me who usually don't use textbooks). Because of the way Gould teaches this class, you end up feeling extremely prepared by the time exams come around! If I didn't already have my heart set on medicine, I would totally love to major in Statistics because this class was just so interesting to me. 10/10 would recommend!

Honestly, the best professor I have had at UCLA for Math or Statistics. Take this class and you will 1) get an A 2) Learn statistics 3) Be taught by a caring, funny, and beast statistician 4) Be frustrated by how long it takes to receive your grade but when you do, be happy that you received an A. He gives out his skype and aim accounts to all students and emails the entire class after practically every lecture to make sure everyone understands the material. Amazing professor!!!

Winter 2023 - Summary: TAKE STATS 13 WITH PROF KIM!!! I CANNOT STRESS THIS ENOUGH! HE IS PHENOMENAL AND YOU REALLY DON'T NEED TO STRESS ABOUT YOUR GRADE IN THIS CLASS! Lectures: Professor Kim is as engaging and fun as learning stats or math can get! He is very funny and likes to make little jokes and comments. Lecture attendance is not mandatory but Bruincast is not the best quality where you can't really clearly see the symbols on the board. He also goes through a lot of theoretical stuff and goes through the reasoning why we use certain formulas but they aren't really important in exams. I have never had a stats class before but I definitely loved it! Lectures moved very fast and can sometimes get confusing but you can definitely rewatch the lecture and stay on top of it. Homework: Homework was only 3-5 problems depending on the unit and only took 30 minutes to 1 hour. He provides a lot of supplemental practice problems in addition to homework so if you just follow the steps in the supplemental practice problems you are guaranteed to get a 100% most of the time. We had homework due at the end of the week for most of the week. He even canceled one of our homework assignments. Labs: EXTREMELY EASY! It is different from LS30A/B and if you had prior coding experience, it should be very easy but different. The lab manual and TA's basically handed you the code so it was never a stress for me. Just ask for help! Midterm: The one midterm was only 20 questions of multiple choice. It was a mix of both calculations and conceptual questions on why we use a certain statistical test, why we use a certain technique, etc. The midterm was very easy! However, beware of his test answer options! His questions have a lot of "none of the above" or "all of the above" options and often times those were the right answer because of a small detail! READ EACH QUESTION AND ANSWER CHOICE CAREFULLY AND DOUBLE/TRIPLE CHECK YOUR WORK! However, the midterm is literally the same difficulty or sometimes even easier than the homework, practice problems, and practice exams. He also gave us a sheet of notes front and back. Final: Same as the final just longer but only should be taking you a hour and a half max. It only tests on the material after the midterm but a lot of the concepts build on top of each other anyways. The amount of statistical tests you learn by the end and can get tested on is overwhelming but he did a review session during lecture and summarized all of them for you. You have your sheet of notes and I highly recommend writing down the different tests and their properties, etc. Make sure to check your work!!!! Extra Credit: He gave us the opportunity to get 5% extra credit added to our overall course percentage which is EXTREMELY GENEROUS! All you had to do was write/type clear lecture notes and submit them. You can make them fancy or you can just submit sectioned bullet points with all of diagrams, formulas, etc. He gives you a whole week from the lecture to turn it in so you can turn it in at your own pace. This class was the least of my worries and actually made me love statistics even as a person who doesn't really like math!

Summer 2018 - Professor Lew is one of the best professors for STATS 13. Her office hour is super helpful in clarifying the materials. She did not push her students to learn all the materials. Instead, she really wants her students to understand the materials well before moving on to the next chapters. This class does requires some times in reading the textbook and coming to her office hours, but it is all worth it when you finally received your grade.
