太有考试了，最后一节课的一个小点考十分 一整个vector就考一个2分的填空，上课梦到什么说什么，板书像听课睡着时写的鬼画符。如果你是数学专业，去上PIC10A吧

Hi, just coming on you to affirm what others are saying. If you got an A in this class, good for you, but please do not lead people astray. This class is insanely easy. I have loads of coding experience and in comp sci, yet received a 71% on the midterm which tanked my grade. He didnt curve it even though the average was a 74% and despite getting almost everything correct, my code didnt compile because of minor errors and I was marked down 30%. Its honestly ridiculous. He is a nice enough guy and a decent lecturer, not as good as any other that teaches 31, but his grading policies are unfair and cryptic. on top of this, the projects are relatively easy as long as you put in the work, but if you so long as put an extra space before the output and the specs said otherwise, you will recieve a 0, and if the rest of the class did fine, you will be screwed and will not do well in this class. He doesnt care what you say to him, so dont bother emailing or seeing him in person, and if you do not have experience getting programs to work first try for hours upon hours of leetcode, avoid him at all costs because his tests are not fair. You will leave the room feeling confident as every and the next week you will bomb, it doesnt matter how prepared you feel, which just leaves you asking what you are even supposed to do next time. For the final, he doesnt give you youre grade to it but rather adds a little suspense so that when you open your transcript down the line, you just end up with a few letter grades lower when you also thought that the final was light. Takeaway: there is nothing you can do in this class to optimize your grades, and you will have to get insanely lucky that you dont make any MINISCULE mistakes, that the name of the game. He is just so rigid in his ways and not willing to listen to the students even if we all despise his grading scemes. Please avoid if possible, I tend to have good opinions on most professors if they are reasonable, but he is not.

vague instructions and unreasonable marking scheme

Easy A tbh

If you have no prior coding experience, I would suggest not to take CS 31 with Huang if you have any other options. I took him for winter, but had to drop week 9 because I had no fucking clue what was going on in class. He stutters a lot and can barely get out a coherent sentence. He's difficult to understand and he often leaves out little details that would make the material easier to understand. He's a bit all over the place. As I write this, I'm currently taking CS 31 with Stahl over the summer and he has been great. 10x better than Huang. Anyway, Huang just isn't a great lecturer. You can tell he likes teaching the class and is passionate about CS in general, but he just isn't an effective lecturer.

Okay so as someone who has done a year of high school coding Java this class was cake. It was a bit of a learning curve with C++ but they are very similar. I barely had to attend lectures/discussions except for in the beginning. However, I agree with another review I saw that if you have never coded before Huang is a little challenging. I would definitely utilize discussion time as mine was pretty much 2 hours of office hours. You can get plenty of help in this class especially since piazza is available and people respond super quick. Huang also realized people were struggling with grades at some point and added extra credit quizzes and extra points to the final and also moved our midterm online bc we wanted it to be. He cares a lot about cs and his students just really make sure u attend lectures and utilize discussions and piazza for project help if you have never coded before!

Listen, if you don't have coding experience do not take this class. All the good things you're hearing about Huang are from people who already know how to code. I have never coded before and Huang made this class so unnecessarily stressful and difficult. His lectures were extremely boring, hard to follow, and plain unhelpful. He clearly did not know how to teach coding at a beginner level. His tests aren't hard but he doesn't teach well enough for the content that is on them. The midterm was taken during week 4 or 5 and wasn't graded until week NINE. And even then some people's tests weren't even fully graded. I got a C- on the midterm which was around the average which was so nerve wracking and stressful since the final was two weeks later. Luckily he offered an extra credit quiz for up to 12 points on the midterm which alleviated some stress. The only reason I ended with an A is because we were allowed a cheat sheet on the final and I had exactly what was on the final and exactly an all-or-nothing 10 point extra credit question written on my cheat sheet so I ended up getting a 102 on the final. As for projects, his specs are actually TERRIBLE. He is so bad at explaining what he wants which results in the project averages to sometime be in the 70s and 80s. But again, if you have done programming before you will get an A, but if not it will be unnecessarily stressful.

i took this class as a non-STEM major so take this review with a grain of salt. Professor Huang is a great person, but he sucks at lecturing. what i mean is that he is very accommodating to students' opinions but most of the time, i feel like i am self-studying for the projects and exams. but i do think that's how it should be at UCLA regardless of what class you're taking. the TA's and LA's weren't that great either because i would ask them a couple questions regarding code and they would reply with a generic answer. overall, a pretty mid experience with this class.

This class was a joke, two lectures form 4-5:50 on Monday and Wednesday where he would sit in the front of the class and talk without a microphone to 150+ ppl(the first week there were like 200-250 ppl). If you were sat anywhere behind the 7/8th row, you had no chance of following the lecture. Lecture was not very useful but he uploaded videos that clarified the concepts on bruin learn. I have to add that this class only has one midterm that is 25% of your grade (that we took week 4) so if you do badly on that you're cooked. It's standard in the COM SCI department (i think?- most professors do it anyway) that your project score is capped by the mean of the midterm and final +30 points (so if you get a 50 and a 60, your project score is out of 75% not 100%), but having one midterm really screwed me over. I got a 90 on the final and a 98 on the projects (which imo where WAY easier than they should have been), but I hadn't quite grasped the concepts of project 3 when we did the midterm (midterm was on Wednesday and project 3 was due on saturday) so I went in and bombed it because 40% of our grade was about loops. I got a 40% on my midterm (it was graded week 8). This was obviously my own fault but I felt like they were grading unecessarily harshly. Also it was online so there was definitely cheating (it was on respondus lockdown browser though). He did give us an extra credit quiz which increased our grade by 12%. I got an extra 8.6% because of it, which was the difference between a C+ and a B- for me and I am very glad he did that. But he made it seem as tho u were guaranteed a 100% if you did it and it was definitely not like that. It was easy enough though. Overall, I think you should take another proffeser but if you gotta take Huang, just keep in mind that you're going to have to put in a lot of outside effort (W3schools, LearnCpp and I recommend C++ for beginners by Dr Kung-Hua Chang (this book SAVED me for the final)). He was really helpful during OH and piazza was really helpful (although some of the student's questions confused me more than helped me), and also my TA and LA were great.

This class was okay. I've taken APCSA and had a very good understanding of that material (not much after), and that's pretty similar to about 75% of the course material. If I had done any CS before, however, this class would have definitely been pretty difficult. I feel like my prior coding knowledge and general intuiton and experience in CS carried me through the projects and tests.

There were 6 projects. I'd say the 3rd one was the hardest and even that wasn't too bad. I got 100's on all the projects except for the 5th one where I missed a small edge case, and there were two test cases out of 10 that covered that.

TA's are active on piazza to answer questions. The project specs were mostly okay but a few parts definitely did need clarification, so please ask your questions (even if it's just a clarification)! A couple times just browsing piazza made me realize I interpreted a part of the assignment incorrectly and had to change it.

As for Huang himself, his lectures are all right. Again, since I had cs experience before it wasn't too bad to follow, but I did feel it could be a bit unorganized sometimes, especially when he would switch between several files at once and showing different pieces of code.

There was 1 midterm and 1 final. There was also a 12 point extra credit quiz to be added to your midterm score, and a 10 point EC question on the final (all or nothing). On the midterm, there were 2 MCQ's graded incorrectly (that they did regrade eventually), and I incorrectly lost 5 points on one of the FRQ's too and had to ask for a regrade, so my actual score was 10 points different than my initial (which is pretty significant and made it pretty stressful). There was ANOTHER grading error on the extra credit quiz which was honestly a little frustrating. In the end they did take care of regrades so it was all good, but it definitely added some unneccessary stress to the class.

The codewriting parts of the exams were probably pretty fair. The mcqs were mostly okay too but there were a few trick questions so read them carefully. I don't have too much of an opinion in this class. I did well but I wouldn't exaclty say I really enjoyed it too much? It was fine overall.
