This review is written during remote learning. He gives extra credits for frequently attending live lectures. Homework is challenging, but still doable, so don't procrastinate until the last minute. Exams are very tough, approaching Christou level. He gave us 24-hrs to finish exams during remote learning. Partial credit is a beautiful thing, so just write down everything you know. Study his lecture slides well for exams.

Professor Amini sincerely cares about student learning. He often stops during lecture to ensure we can understand, and will answer questions patiently. I think he struggles a little with the online format, but he cares about our grades and our learning. He also makes an effort to know the name of every student who attends live lectures, which I really appreciate. Professor Amini is a kind, generous, and decent instructor.

The coursework is based on 7 homework assignments (20% of overall grade), a midterm (30%), and a final (50%). The homework assignments were sometimes challenging but not too bad, and the TA went over a lot of the questions during section. The exams were 48-hour exams, and they were pretty tricky (some of the questions genuinely felt like trick questions), but in retrospect, they were doable, and Professor Amini has an exam-writing "style" that you get used to after the midterm.

It seems that the negative reviews have been downvoted, and even though overall I had an alright time in this course, I do see where they're coming from. To me, it definitely came across as though teaching this course was not a priority for Professor Amini; he was several minutes late to every lecture except the very last one, did not plan out and announce exam dates and times until the week of/the week before, needed to be reminded by students to post class materials (such as lecture slides and exam grade distributions) in a timely manner, and encouraged students to use Campuswire rather than emailing him but then proceeded to be pretty inactive on Campuswire. I totally understand how difficult it can be to balance professorship and other life responsibilities during the pandemic; the above is just my own observations from this past quarter.

Overall though, I did get the impression that Professor Amini cares about students' learning, and he always made time for questions during lecture. And since the course material/assignments were relatively doable, in the end I would recommend 100C with Prof Amini. Just be prepared to not have the same engaging experience that you may have just had in 100B with Prof Christou.

I really think Arashi is an amazing professor. His lecture notes are crystal clear and organized, and he would upload all of the lectures to youtube so participation is optional. He would always pause a little bit for our questions, so you could easily tell he cares a lot about the students. The homework takes some time to finish, but the exams are definitely doable if you understand most of the topics covered in this class. If you want to master the skill of linear regression and are willing to take some challenge, Arashi would be the perfect choice for you.

Tests were hard, approaching Christou level. Amini was a decent lecturer and a funny guy, and helpful in office hours. I'd definitely take another class with him.

This class was HARD. Like, it's definitely true when people say it's the hardest stats class at UCLA. But, I really liked Amini as a professor. His slides were super clear and concise, and they were soo helpful when doing the homework. But, be warned, the workload is HEAVY. The homework took me days to complete, and they were graded on correction through Gradescope. But I think the graders got really lazy by the end of the quarter, so they were pretty lenient about grading, which is nice. Amini had a midterm and a final, and they were both ridiculously and insanely hard. The averages on both tests were Ds, I'm pretty sure, but the curve was really good. He made the final open notes, book, and even laptop, but tbh it didn't even help because it was that hard. Still, I think his curve saved me. Overall, I really enjoyed this class because you get to learn about linear algebra as applied to stats, and Amini made it really clear to follow! But his tests and homework were really hard :(

The professor has no responsibilities at ALL. Due to coronavirus, the final was arranged as an online take-home exam. He claimed that the final will be updated at a specific time but after all, he delayed for 3 hours with no reason. Besides, he even set the wrong due date of the final after it has been posted.
Most of the students in the class expressed their concern about the final that will cause stress to the fellows, but the professor insisted to arrange it and said he will TRY to explain the reason of it. However, he did not leave a word after all.
Besides, the slides and materials are unorganized and definitely not helping you to understand the subject. Boring and useless class. Be prepared to study by yourself :) Avoid if you can.

I really enjoyed taking 100C with professor Amini, I took this class along with 101A, and I can safely say that I gained all my understanding from 100C with Amini.
It is a theory heavy course, which I really appreciated, because this course really provides some absolutely essential understanding for statistics.

There was a lot of homework, but I learned a lot from doing them.
Tests were hard, but appropriately, although a bit more time would have been nice for the final, I ended up rushing through the last questions.

Prof Amini prefers having people participate in the lectures, and turn it more into a sort of discussion session, which was rather refreshing.
If you are not afraid to put yourself out there, and participate in class, this is a really good class for you.

Anyways, hard, I learned a ton, 10/10 would take it again.

The materials of Stats 100C are very hard and abstract in general. Fortunately, Dr. Amini is understanding and allows us to take tests online. The homework gets harder as we approach the end, and it is a bit difficult to complete them without committing a lot of time rereading the slides. Some of the slides are too long and make it very hard to review, but Dr. Amini's lecture is engaging and he explains everything he writes carefully. I hope the slides will be more organized (especially MLR) but other than that Dr. Amini is kind and helpful!

One of the WORST professor of this department. He always asked us to watch previously recorded lectures before we go to the class, but after doing this I found it useless to go to lectures or watch current recorded lectures. The reason is that the content of previous videos is basically the same as that of current videos. Amini cannot explain concepts well, and his lectures are lack of concrete examples; instead, there are tons of dry theorems and lemmas. Sometimes he skipped some concepts or spent little on time them, and those content turned out to be tested on exams. When it comes to exams, both midterm and final are very hard, often relating to untaught or unemphasized concepts. The overall feeling of the class is so bad that i would never take his class again.

This class is fairly hard, as expected. But as far as hard, mathy, stats classes go, I honestly liked this one. Amini recorded everything and posted the lecture slides he writes on in class, so you don't have to go to class at all. The lecture slides are honestly amazing (when they include his writing after lecture). The slides were enough for me to gain the understanding I needed. The exams are doable, much more so than Christou's (and you get a day or more to do them). I have no doubt many people if not most of the class was cheating/working together on them because there was nothing stopping you. The one thing I would say is that he ended up keeping track of who went to class and boosting the grades of people who went to class a lot, even tho attendance wasn't mandatory. That's kind of dumb in my opinion.
