Lectures are above-average quality and can get a bit wordy, but Prof. Leary is very approachable and helpful during office hours.

Honestly, if you did well in Calculus AB or BC all you need to do well in this class is do the homework (which is part of your grade anyway) and do the practice midterm he provides a couple of days before the test. I would say the practice midterms are fairly similar to the actual midterm. He is straight forward when covering the material and what you need to know. However, since his tests tend to have a high average, I don't think he curves the class. If you're struggling, he is super approachable and vey willing to help.

Highly recommend this professor.

Brian (he told us to call him Brian) is such a chill guy. He's so good at teaching math... he uses super clear examples and always explains things. He's super helpful during office hours and will answer all of your questions. Would definitely recommend for a first year taking their first math class at UCLA.

Professor Leary definitely has a passion for what he teaches and this shows in his lectures. His lectures are usually clear and straightforward, and the homework he assigns helps students apply what they have learned in class and tests their knowledge on the mathematical topic. There are two midterms for this class, but they were both manageable with no confusing questions. However, the final was definitely more challenging, and I did not expect it to be this difficult. I struggled with some of the problems, and I left the final feeling very unsure of my grade for the exam. I do not think he prepared us enough for the final exam.

Leary was my favorite professor last quarter. His lectures are incredibly straight-forward and the examples he explains in class are directly applicable to the small amount of homework he assigns every week. The tests are very fair and he's very approachable.
Highly recommended!

Class is pretty easy, but this guy writes everything, I mean, EVERYTHING, that comes out of his mouth onto the whiteboard. For simple proofs, he can easily use up 4-5 of the 6 sliding whiteboards in A51. And don't get me started on his code for algorithms; you will write down a full page of pseudo-pseudocode, and in the end have no idea how to do whatever he was teaching.

Professor Leary is a great professor. His lectures are very clear and organized. He welcomes students to ask questions during lecture and he is very patient answering those questions so don't be afraid to stop him in class and he'll explain to you what you don't understand.

Grading breaks down to two midterms and a final, plus weekly homework assignments. This may sound like a lot of work but each assignment only has a few questions and you can drop the lowest assignment score. He also allow you to drop your first midterm after the score comes out and put more weight on the second midterm and the final. All of these make this class a pretty easy one, definitely manageable.

Another great thing about professor Leary is that he let his student vote before he makes changes in homework assignment, review session schedules and even whether or not he allows cheatsheets on the final!

Take professor Leary for 3C and good luck studying :)

Dr. Leary is a straightforward lecturer. He will explain a concept and then run through examples. I thought the workload was very fair; he only assigns a few problems for each section. In addition, he provides practice exams which are a good representation of the actual exam. If you have a question, go to his office hours! He is very approachable and friendly, and will make sure you understand the concept.

I had Leary for 3B, so I was used to his lecturing style. I like how he explains a concept and then goes through example problems. 3C is the last class in the 3 series and centers around probability. This class was challenging because I did not have much exposure to probability before this class. Tests were difficult because of the wide range of problems that can be asked. I went to his office hours and my TA office hours in order to understand the concepts in this class.

Leary is a pretty bad professor. He writes literally everything he says on the board and so going to class is equivalent to having the book read to you. Tests are fair, but everyone does really well which means that even missing one question can cost you a good grade. The main issue I had with the class was that the graders basically graded half of the assignments in the class incorrectly but Leary didn't really seem to care. This means that how much you know doesn't correlate well with your final grade. Overall I wouldn't recommend this professor.
