Do not take this class. I went into the final with 100% and it was extremely difficult compared to the rest of the work we did in the class. The masses blatantly cheated on the final without consequences sharing answers in line, chatgpt, swapping papers. I've never seen anything like it. I got an 80% RAW and ended the course with a B+. Such bs.

I've received an insight that something is going to happen. Although more people reporting this incident (clearly not to TA or Prof as they do nothing) is vital. Remember, the TA's and prof arent going to take th incident seriously as it is a major fault on their ends!

Hated this prof but I just got insight that something will be done about how bad the final went so I'm hoping I'll be brought to justice

If you failed the final, it means you actually know what you're doing because you likely DIDNT CHEAT on the exam but got f'ed by your classmates who did. A grade doesnt determine your worth!

I can deal with a bad math professor! What I cannot deal with is someone who allows students to cheat on a final worth so many points. Accountability has been lost and I am sorry for the clsss and students who had to endure this treatment!

OMG JUST DONT TAKE THIS CLASS WITH HIM PERIOD. is anyone gonna do anything about the finals cheating scandal. This needs to be investigated and will be reported to the highest level possible.

Got an A+ but lost my sanity on the final, even after getting a 100. Those numbers for pink was surprising. 60% Final really do be messed up.

The overall score is only related to the final, and final accounts for 60%.

1. Everyone cheated so there will be no curve for the people who actually did the final 2. 60% is harsh a 100% means nothing before the final 3. There was a way harder version so even if there was a curve he obviously wouldnt take that into account

Content wise: good pacing, lectures are somewhat unclear but helpful. Lecture/HW is not enough to learn the material, outside studying is required. Grading: 60% of grade final, lots of ppl cheated; hard but fair Qs. This prof. has a much worse grading curve than other profs (C vs A avg), but getting an A is doable if you study hard outside class.

Nothing else matters in the class except the final, which was one of the worst finals I have ever taken in my life.

Professor Dai's class feels unfair due to widespread cheating, with phone usage visibly occurring in the exam halls, yet no meaningful action was taken.

Prof Dai is a really passionate guy that you can tell cares a lot about his students. His lectures are indeed a bit unclear, but I genuinely think they do help to just absorb information if you attend them. Supplemented with a few online resources, I felt pretty comfortable with the content. Don't listen to the rest of them.

Prof Dai is genuinely a nice guy who seems caring and passionate about what he teaches. Unfortunately not a great lecturer. If u want a good understanding of linear algebra don't take his course. If you want to chat gpt ur way thru to get an A, then I highly recommend this class, since he lets u use ur phone in every exam (but not calculators ofc).

There is a reason why 43 (make it 44 now) of the 134 reviews he has are 1 star. I'd give it zero if I could. TA Nicholas is just as bad as Professor Dai. I asked him for paper during the final and he practically threw it at me. If you're unhappy proctoring an exam (doing your job), Im sorry, but don't take it out on students who are stressed enough

OMG is it just me or did everyone hate the final? So bad for students who actually studied and good for the ones who stood in line, copied off of each other, and used chat gpt (you know who you are.) One girl even went the bathroom to do her final. Why weren't the TA's doing their job of proctoring an exam so academic integrity is maintained.

I don't even know what to say about this professor and class. Would not take again. The final exam was harder than the midterm, which clearly did not prepare anyone for the final. Everyone was using phones to cheat, and copying off of each other changing answers outside of Campbell Hall while in line. Where do we draw the line of academic honesty?

The midterms are so easy that you can basically finish them under 20 minutes with 100% In this class, the lecture notes are not helpful at all. The notation is quite different from the textbook; Professor Dai is really bad at summarizing the theorems. The final should be one of the hardest linear algebra exams among all US public universities.

Honestly, the 60% final can really screw you over, however, the numbers on the final were high, but taking your time and checking each step goes a long way... A bit screwed up for him to do that but all the other problems were fair. So I wouldn't really say the final was hard. Dai's lectures are optional; just look at the slides and learn yourself.

Lectures are really not great, slide concepts are explained weirdly or breezed thru. The midterms are super easy and then the final is insanely hard. This is compounded by my test version being uniquely bad, with insane fractions and stuff for a no calculator test, and the fact that so many people were blatantly cheating w/ AI or talking to others.

This examination was absolutely out of control. Not only was the test difficult but the exam security was jeopardized when students were outwardly cheating on the final. This is not okay and hopefully gets addressed. It is not fair to the students who put in the time and dedication into receiving a fair grade!

What a mess. Ragebaits you with two easy online midterms with no proctoring and gives you an unreasonable final. The final isn't hard but the numbers he gives you to do RREF with was absolutely insane, with huge fractions. Cheating scandal was prevalent as well, and the only saving grace about Prof. Dai is he's a nice guy and has good slides.

I'm not sure whether UCSB has an academic integrity office, but they should really look into this final. I've never seen so many students blatantly cheating on an exam worth 60% of the grade. What is the exam even aiming for? Testing the strength of AI? I know supervising 700–800 people is hard, but what happened was still ridiculous.

This is the worst class I've ever taken. The final was worth 60% of your grade and nearly impossible without a calculator. There were two different versions of the final—one was reasonable and the other was horrendous. It was almost entirely fraction answers and ridiculously hard. Dai is also a terrible teacher.
