Meka is organized and nice, but he assumed we knew a lot more coming into the class than we actually did. He would present topics without a lot of lead-up, so you'd be suddenly looking at things like advanced probability without having taken any statistics classes (and even the people who had taken those classes said that they'd never seen before the material Meka was presenting).
Classes are all about new material, but there wasn't a very cohesive chain of applicability for all the different topics, so it made it hard to absorb the info; it just seemed like a big bag of difficult, seemingly disjointed material.
Meka's a nice guy, but he tended to not tell you how to do things for fear of "giving away the answer". Consequently, any methods you developed to solve any questions was of your own doing.
If Sean is still TAing, he's a big help.
Overall, I feel like the class was unnecessarily hard and you didn't leave feeling like you had new tools in your coding arsenal; you just left feeling glad that it was all over.

If you are in this class, here are some things that can help:
He sticks fairly close to the book, so if you can read the chapters before lecture, you’ll be ready to hear his advanced versions of the material.
The homeworks were ridiculously hard, but once you have the answers (TA help…), really understand how you got there, because his exam questions are often just versions of those HW questions (and/or versions of some proof he did in class).
He really expected us to reference algorithms/proofs he did in lecture. If you can remember all those, you only need to add “blah blah algorithm/proof, as shown in lecture” much of the time for full points. In fact, NOT referencing one of those can often wipe points off your HW/exam even though you did everything else right.

Overall, the HW grading was up and down (high average for the class on one assignment, then an inexplicably, drastically low average on the next) and we often weren’t sure what constituted a “correct answer” because the instructions were vague, yet the grading was very specific, like a N Campus class looking for you to mention key words to match the grading rubric.

Like I said, perhaps his teaching methods will change and he did grade fairly with the final grades, but I would recommend someone else if you want to really “get” algorithms.

This is by far the worst professor and class I have had at UCLA. Meka may seem like a nice guy on the surface but he does not by any means prioritize student's best interests in his classes. He believes that his class is the most important thing in your life and that he is upholding a high academic reputation for his class by being a d**k about grades. A classic example is one time the TA lost a students hw assignment, he gave the scores out on a Friday before a final, and when the student complained about the 0 on Saturday and asked for a regrade he told him no because he deemed it too close to the final exam.

HW assignments are graded extremely harshly. You will spend hours doing them and then get destroyed during the grading. If you try to reason with Meka and complain about your grade, he will not help you out.

Bottom line is that if you dislike yourself and would like to make your algorithms experience as terrible as possible, go ahead and take Meka. I actually hated this class more than 111 with Eggert, which is really saying something.

The time-consuming homework assignments left a bad taste in many people's mouths. They primarily involved providing an appropriate algorithms for particular scenarios and proving their correctness, time and space complexity. Many people felt the grading was inconsistent, but that reflects more on the grader than the professor. Solutions to each homework was provided, so after one or two assignments, it was more clear what was expected from us. Although I spent multiple hours on each assignment, in many cases, coming up with the algorithms did not take nearly as much time as articulating the proofs clearly and thoroughly. I ended up with a high grade in the class, but I definitely didn't feel significantly more prepared for tech interviews as advertised.

Quarter Taken: Spring 2015 Submitted March 29, 2016 Grade Received: A

The lectures were clear. The algorithms and proofs he presented in class all seemed to make sense. The homeworks were extensions of these algorithms and proofs. Sometimes the extension was a little too far, which made the homeworks pretty difficult and time-intensive. You learn what he expects after the first assignment's solutions are posted. I think a lot of people aren't used to the rigorous proofs he expects, which made them unhappy with the course. I would agree that I would've rather written some code for these algorithms instead of worrying about the proofs so much.

The exams were easier than the homeworks (as you would expect, since the homeworks took so long). If you understand what you did on the homeworks or at least why the solutions posted are correct, the exams should be pretty straightforward and you should get a pretty good grade.

Meka has made the course workload and exam difficulty very reasonable since he last taught it in 2015. Textbook is not needed, just focus on lecture slides which are posted online, and homework sets. Sometimes in lectures Professor Meka goes over complex proofs (such as runtime of Quicksort/Quickselect) but he generally does not give exam questions on these.

Quarter Taken: Winter 2017 Submitted July 9, 2017 Grade Received: A+

Meka went through most of the topics on his iPad and Apple Pencil, which basically is an advanced white board. He will post the transcripts immediately after the class. In general the course is very well organized. There are 3 exams (including the final), which are all roughly equally weighted and are not accumulative. Really necessary to point out that a lot of the comments on Bruinwalks are not fair at all. He is a great professor if you want to take 180 with him.

Quarter Taken: Spring 2018 Submitted June 7, 2018 Grade Received: N/A

Meka's class is much easier than the other options for CS180. He writes out the content of the lecture by hand but on an Ipad that he projects. He draws pictures and even uses colors!! It's very awesome for people who learn better with pictures :) Also all of his lectures are recorded and available on CCLE so you can rewatch the videos to prepare for the weekly quizzes/hw/exams.

His HW is pretty easy as long as you understand the lectures. If you understand the lectures, you will do well on the tests - you don't really need to think outside of the box. Downside is the class averages on the tests are like 89% and he gives 30% As, 30% Bs, etc.

This class reminds me of a high school class, where you could kind of just memorize what you learned in class and get 100% on the test from that alone. The good ol days ...

Professor Meka was an excellent professor. In this quarter we had BruinCast, as another reviewer mentioned, but Professor Meka noted that he didn't like the drop in attendance so if you take the class with him I wouldn't count on it being BruinCasted in the future.

Even without BruinCast though, I highly, highly recommend Professor Meka for teaching CS 180. He was extremely clear, very good at teaching the material, and always stopped to answer questions. Additionally, the homework he gave was suitably challenging in relation to the tests, so that if you did the homework and the additional practice he gave you, along with reviewing quizzes and your notes, you can get above average on the tests.

However, note that the course gets considerably more difficult as the quarter goes on (it still isn't bad by any means, it's just that up to the first mid-term is actually quite easy). Make sure to more closely go over notes, quizzes, and do extra practice problems for the last two-thirds of the course.

Also, the average on the first midterm was slightly above a 90%, while the second midterm average was around a low 80-high 70s average. I suspect the final will have a similar distribution as the second midterm. He gives 30% As, 30% Bs, 35% Cs and 5% Ds and Fs. Fairly standard distribution, just try to beat the curve.

Mid-terms are also non-cumulative, which is really nice for a CS course. I highly recommend Professor Meka to anyone who wants to take him for CS 180.

Quarter Taken: Spring 2018 Submitted June 16, 2018 Grade Received: B

although pretty willing to receive feedback, i found his teaching style incompatible with me. i really felt like i wasted my time in this class. i dont know why we spent so much time on basic things like divide and conquer, bfs/dfs, etc. i felt like there was so little depth to the class and the proofs were extremely bullshitty. he did randomized algorithms instead of network algs my quarter, which i thought was kinda cool tho.
oh, his handwriting is not good. also his sense of organization for his handwritten notes is straight trash. i literally cannot understand what the guy is trying to convey. also, lecture is extremely slow and boring. although it was bruincasted this quarter, i think he said he won't be bruincasting it in the future :(
overall, i thought this class was a waste of time because i didnt really learn anything except some vague stuff on NP and randomized algorithms. everything else i already learned from leetcode.
oh, but yeh the tests are noncumulative and he answers all questions on piazza + lecture (literally every single one) which is really helpful imo.

Quarter Taken: Spring 2018 Submitted June 18, 2018 Grade Received: C+

While the professor was very active on Piazza, which was nice, I don't really feel like this is a class worth taking if you want to actually learn something, as we covered less material than other CS 180 classes have. The professor pretty much just regurgitates chunks of the textbook but in a confusing way. The quizzes were quite annoying; each timed quiz was worth 1% of your grade and there were 10 total, so forget a quiz or mess up on one and you'll be saying goodbye to those points (I said goodbye to quite a lot of those quiz points). I found that the exam structure was also a bit unforgiving; I was really sick during the time of the second exam and ended up doing extremely badly on it, which ultimately ended with me earning my first C.

The biggest problem with this class, though, was the cheating. The high homework and quiz scores were not due to the fact that the students were especially smart, but due to the fact that the students were especially inclined towards cheating. I saw and heard people pass around homework answers; I was even offered some at some point when I asked for help. To prevent cheating, at least a little bit, the professor should use different homework problems each time he teaches the class or something so that people can't just look up the solutions on Chegg.

Overall, I wish I had taken this class with a different professor, because I don't think I learned much at all, and all that this class left me with was a bitter taste in my mouth. To put things in perspective, I would rather take EE M16 with Mehta again than this class.
