Absolutely horrible class. The homeworks are way too difficult and uncomprehendable, so you cant even get a normal basic understanding of the course material. HW is graded 1 to 3 subjectively, so you can't even really know if you're doing well on the HW since there is no rubric! Absolutely horrible, if you can avoid this professor, please do so. Take Reinman, who is actually an amazing professor.

Horrible class, Avoid this class if you can.

...this class was one of the worst classes I took at UCLA after 3 years. The homeworks are impossible, though they don't count for much (7% of the final grade). The tests are equally as difficult, and during the online learning he made us type our solutions in LibreOffice, a terribly designed Word knockoff that is a pain to work with. We also had to type our exam solutions in LibreOffice, and it was so unnecessary and confusing that he even made us take a practice dummy test to get used to the interface. My biggest regret is not taking Reinman for this class. WAIT AND TAKE REINMAN IF YOU CAN!!!!

好人一生平安

Unfortunately this is a terrible class taught by a terrible professor. He is unhelpful and rude to students during lectures, calling them out when they can't answer his questions. Homeworks and exams must be completed in a weird old program that's hard to use. Tests are completely opaque and subjective, graded very harshly--the average score on our final exam was around 25%. Avoid this professor if you can!

Tough class, but pretty fruitful, learned a lot , but worked a lot too. Keep in mind, there is a lot of difficult work but you'll end up understanding a ton of hardware stuff.

This class may be just another hard CS class for some, but to be honest, this class gave me a much deeper appreciation for CS than any other class at UCLA. It helped me connect my understanding of coding by itself into the more comprehensive understanding of how computers interpret those instructions at the processor level. Bringing all those concepts together really sparked a greater interest in CS in my mind, and I have Yuval to thank for that.

Yuval is not the greatest professor I've ever had. But he's a good one, all right. And make no mistake: this class is hard. Processor logic and computer architecture are nothing to scoff at. But frankly, this is what I would call a fair class. You know what's expected of you, the class material is difficult but straightforward, the professor is always available to answer questions (even giving us some advice for grad school, of all things) and he was very concerned about our growth and learning in this class. The homeworks were a bit long as others have mentioned, but they were incredibly satisfying when you finish them. It doesn't feel like a lot of this work is unnecessary like in, say, one of Eggert's classes. It serves a purpose in understanding specific concepts and preparing for exams, and I feel much more knowledgeable after having taken this class. Also, I'm not sure if this is different now, but when I took the course, almost half of the homework questions were optional, there in the course website to help you hone in on stuff you need more practice with. The required homework questions were never excessively long in my opinion.

My advice would be to focus on the homework questions, find someone with whom you can study homework questions together (being mindful of course to always write down the answers yourself and note your collaborators), ask good questions and be engaged with the material, and you're honestly all set. Thank you, Yuval, for a great class.

Great lecturer, concise and clear.

Man I studied so hard for his class ended up with a C+(Student with a 3.2 GPA).
I literally put in more time into this class then any other class.

If you get the stuff you will do well, if not you will struggle. The homeworks were impossible. They dont carry any wieghtage but it is really discouraging. He does not help you out in office hours and is very strict.

People might say he is knowledgable and stuff but i really did not like his class. Just take it with Reinman or someone else.

Mixed feelings about Tamir.. but in the end he isn't bad.

tips:

1) don't stress about the hw. do it, of course. But if you get stumped dont stress because it's worth close to nothing. don't bother going to office hours before the hw is due though.. it's pretty worthless. just turn in as much as you can do and REVIEW THE SOLUTIONS AFTER. If you still dont get it office hours might help.. but before he posts the solutions he isn't going to help you or nudge you in the right direction. It's pretty frustrating.

2) for the exams, REVIEW THE HOMEWORK and the solutions. He makes the exam average 70% and the curve is pretty generous for course grades.

3) i heard he reuses homework.. but old hws wont really help that much at the end because hw isnt worth that much of the grade and he posts solutions to hw so you can study for the final and mt.

4) lectures are actually worth attending but if you miss them it isnt a big deal. He took time out of lectures to talk about grad school (he prepared slides about it) and twice he did "advanced" topics that were just fyi.

Great lecturer, very organized and knowledgeable - I learned so much in his class. Also, he is willing to take questions and tries to explain things to you until you understand it. Homework assignments were difficult, but it helped me learn a lot of the material. MT and final are similar to his homework problems - study those and the diagrams he goes over in class. If you have trouble with any concepts or homework, go to his office hours. He may seem intimidating, but he truly cares and is willing to talk with you. I recommend taking any class with him.
