# Probability and Stats W3600

Gallego, Guillermo
Probability and Stats W3600

Please keep in mind that this review is more than 5 years old.

Professor Gallego teaches the IEOR section of Prob/Stat.

At first when you meet him, he seems like a very nice and reasonable man. But boy are you in for a surprise. While he is obviously very smart, his accent makes it hard to understand what he is saying. He has very unreasonable demands as to what depth the class should know certain topics.

He provides only a theoretic view during class lectures and doesn't usually give specific example problems. The text book he uses is not helpful either. For every theory, the book only shows 1 example at best and does not fully explain the steps at all.

While we are on the subject of the textbook, "Probability and Statistics for Engineers and Scientists," is a convoluted book that has typos and bad formatting. Even the texbook's name is a ripoff of the STAT W1211 book "Probability and Statistics for Engineering and Sciences." Another fact is that the book used for this class is not on Cramster (which in it of itself is not terrible), but Gallego does not provide a very detailed solutions to the homework problems. In effect it's just a one or two liner about the theory that was reference and the answer. His homework "solutions" aren't really solutions, but just answers, making studying from old homework very hard.

Finally, I would like to address his grading methods. He has his TA grade off for minor issues like a certain way of asserting a proof or having the numbers in the right place. The grading is heavy-handed for the homework. (I don't know many people that have gotten full scores.) He says that he curves to a B/B+, but the other section curves to a B+/A-, which just relatively makes it depressing to be in his class when you see friends in the other section.

#### Workload:

Approximately 1 assignment a week: given out Monday and due the following Wednesday. Homework starts around 3-4 weeks into the semester. He does not drop any homework assignments, but instead allows 5 grace days.

Midterm/Final is nothing like the practice examples that he gives out. (Some of which are 4 multiple choice questions and 6 short answer) The actual midterm/final is much harder, but you can also BS parts of it. The class median for the midterm was around a 63, which I honestly expected to be lower.

Kou, Steven
Probability and Stats W3600

Please keep in mind that this review is more than 5 years old.

I agree that Prof Kou doesn't care much whether he is teaching 100 or 2 people. But actually, if you went to class and made some effort to listen to him and copy his slides, things aren't that bad. Exams are based strictly on homeworks, case studies and recitation problems. So if you took some effort in reviewing those before the exam, you will do great. He won't ask anything he hasn't mentioned in class. I agree, he can be boring and hard to understand but he is quite a nice guy in general, his curve is so good that you will be in the A range quite easily. If you have a choice, you should probably take someone else's class, but if you are stuck with Kou (as most of us are) then make sure you go to class and it's really not that bad.

#### Workload:

Problem sets that can be ridiculously long and time-consuming, but you can learn a lot from doing them. 2 midterms, and a non-cumulative final, not bad at all.
