Love Bruce!! Super nice with grades and gave us an extra credit quiz worth 30 points. Can tell he is really passionate about computer science and tries really hard to help with all questions that come up. Something new for this quarter was that our 7th project was a open-ended design your own type project which I thought was really nice (adding on to/based on project 6). Overall a super nice professor and would definitely recommend taking CS31 with him over any other professor.
Also discussions aren't mandatory but I would recommend doing the optional worksheets as they are really useful in solidifying your understanding of the concepts.

Professor Huang is a great professor and I would highly recommend taking his course. Throughout the quarter, it was very clear to me that he cares a lot about teaching and the quality of the content that he puts out. His lectures and slides are easy to understand and he's extremely accommodating and willing to help out his students. In addition, there were a ton of useful resources available. In terms of how the course was constructed, the exams and projects were fair and the course ran smoothly!

Huang's an energetic professor who explains things well and evidently cares a lot about his students. He was super understanding with misunderstandings in CCLE and would do his best to clarify things through email or on Piazza. Would recommend if he teaches again

If this is your first time learning coding, you are definitely screwed. The professor won't respond to your emails and won't answer your questions on Piazza (ironically, he encourages students to use this rather than email). You’ve got to learn the whole thing by yourself, which takes a lot of time. I have some coding experience from high school (Java), but still struggled with classes in C++ , which felt kind of different from Java.

Some people might say this class is an easy A, but this doesn’t include you.

I really hated this class.
Professor's lectures are so boring and unclear. Very disorganized and basically half the class stops coming at some point. The tests were difficult, at least for me. Small mistakes lead to big grade drops. Projects were the only thing stopping me from getting a C, but I heard for many that was what led to a lower grade, because small mistakes on the projects lead to a zero. Project specs (instructions) are unclear, and mandatory things are only revealed in office hours or later announcements or discussions, which means its always a gamble to whether you do well or not.

Professor is never helpful, neglects emails.
Don't take this class with him.

TLDR: Chill class if you had previous coding experience with APCSA or similar, but may take more effort if new to coding. Lots of extra credit.

This class was pretty chill I would say. Lectures are optional, he posts slides, every lecture is recorded and posted on canvas. His lectures were fine but I ended up skipping all of them after Week 3 except for midterm and final review lectures which were helpful. I also skipped most of my discussion sections but my TA was really nice, super knowledgeable about the course, each week they reviewed course material from the presentations and had a short worksheet of conceptual and technical questions to work on, with solutions posted later.

Grading:
Non-graded Online Checkpoints (5%)
Projects (40%)
Midterm (20%)
Final (35%)

The non-graded quizzes eventually stopped after three of them, one each week, I'm not too sure why but they were just some practice multiple-choice testing the content taught in lecture. 6 projects, each of them were fine, just triple-check that you submit the project in the exact format and follow the instructions exactly as told or else you will get many points taken off. Ask any questions you have on Piazza or your TA to make sure no mishaps happen. The midterm was a mix of multiple choice, fill in the blank, and coding questions taken online during lecture (so 1 hr 50 minutes long but its supposed to take around 1.5 hours). 1 page cheat sheet front+back. One important thing to note is that one of the coding questions was word for word the same question as the online practice midterm coding question. The final was a similar format to the midterm, with a time limit of two hours (cut down from the usual 3 hour length of a final), online. 2 pages cheat sheet front+back. No practice final beforehand though.

Extra credit: Doing the LA feedback surveys for the mid-quarter and end-of-quarter gave 5 extra points to be added to the midterm and final respectively, and since both midterm and final are out of 100 points, it was very nice. There was a 20 minute online extra credit quiz on pointers around week 7-8 lecture time that was 10 points, however many points you got would be added to your midterm score. You just had to be in the lecture room in-person and turn in your 1-page cheat sheet.

Overall get solid grades on the projects, make sure to understand concepts thoroughly for exams, and practice simple coding questions too (or just put code on your cheat sheet like I did). Huang can be a funny guy sometimes too so his lectures aren't very boring.

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.
