I think Professor Hahn gets a bad rap and the reviews make the class seem really scary, but I was pleasantly surprised by this class. Although econ 41 is demanding in material, Hahn is an engaging professor, very clear about the material, and easy to understand. He posts the entirety of lecture notes online as a PDF, including homework problem solutions. It is pretty easy to follow along what he is doing in class.

If you want to get a good grade, stay on top of your work. Go to class, pay attention, and do the homework within a couple days of learning it. TA sections are also really helpful for actually applying what you learned. To study for the tests I made flash cards of all of the concepts and then did the homeworks and TA notes a couple times. The tests don't use word problems and are very conceptual, so understanding formulas and being able to manipulate them will get you far.

My year was a bit screwed up because the final was online, but the grades are usually 40% whichever midterm you do better on and 60% the final. Then, he uses a class rank to curve it. Study hard for both midterms, even though the first one is significantly easier. This will better prepare you for the final, which was pretty difficult even online.

Despite the material being hard and the tests also being hard, Hahn was a good professor and I don't think he deserves bad reviews. Initially I wanted Rojas, but I think the classes are probably equally as hard. Overall, if you're taking Econ 41 with Hahn, don't expect it to be easy. But if you give it attention and practice, it's not that hard to do fine!

Usually, your grade for his class wholly depends on how you compare with other students. Because of COVID, he was more lenient and decided to base it off the average of the 2 midterms we already took OR the (optional) final and the highest midterm. He’s a bad teacher and my TA wasn’t very helpful, so I didn’t have much hope for my grade. Thanks to COVID, I got a higher grade than I should’ve earned. If you’re going to take him, Godspeed and I hope a pandemic will help you out with this class.

Grades are made up of:
40% best midterm
60% final
Professor Hahn is actually quite a clear lecturer - yes, they are dry, but he gets the main ideas across. He also provides class notes online, which is pretty helpful if you skipped a class or two. His class is also very straightforward, his tests are purely math problems without any kind of tricky wording or long intro. However, he does not provide any type of practice problems for the tests, and his homework problems are not really similar to the test questions. This has definitely made it very hard to study for his tests.

Although Econ41 could be some what challenging for some students, and I was also anxious about the class at the beginning of the quarter, it turned out to be a very productive course for me. Prof. Hahn's lecture is very informative and comprehensible that he aims to everyone in the class understand the concept. Most of problems on the exams were very similar to the homework problems, and you can expect a decent grade if you have worked on homework and reviewed the lecture notes thoroughly. I would say about 70% of exam questions were very similar to the homework/lecture problems, and 30% upshoots. Since every problems on the exam weighted equally, Just work on those easy problems first and then move on to those harder problems while taking the exam. You should be able to finish the exam on time.

One of my best prof that I've take.....
He is very clear for me and My TA is also fantastic...
Not enough time to solve all questions during the mid term and final and quite hard
but!! if u feel that feeling, everybody did the same feeling...so plz dont worry just keep studying hard!

Sigh, this class. I actually think Professor Hahn is a very good professor and his online lecture notes have everything in them you need to know to succeed but his testing style is a nightmare. We had to complete 33 questions in an hour for the midterm and around 62 questions in 2 hours for the final. I just found the time constraint to be a bit ridiculous because you have to work through the problems so incredibly fast and a decent portion of your grade is based off of pure chance because you end up having to make a lot of guesses.

The test questions aren't necessarily difficult because there's many that are similar to the homework problems but he does include a handful of "hard" questions that definitely separate out the As from the rest of the class. It's by far the hardest B I have ever earned and I'm glad it's over.

Iris is a wonderful TA but I know she doesn't like TAing for this class so she probably won't be a TA for it again.

Do not take this class with this professor unless you want to suffer. The material itself should not be difficult, but Hahn makes his tests ridiculously time constrained and more difficult than any preparation materials. The course grading is 40% midterm and 60% final, so prepare to be blindsided by the midterm and then have only 1 opportunity to improve your score at the final. Questions are harder than the homework problems or the problems done in class, so there is no way to adequately prepare for the exam questions, especially given the time constraint of around 2 minutes per question. Topics that are emphasized in class/homework barely show up on the exam, while topics that are brushed over show up repeatedly. To make things worse, "None of the above" is the answer A LOT, so it plays mind games even for those who do calculate the correct answer. Also, Hahn does not allow you to see your midterm exam AT ALL to review it. You only receive your scantron back and never get to see the actual questions, which makes it impossible for you to learn from your mistakes.

EXTREMELY hard exams. midterm is 30 questions in one hour. you're supposed to spend less than two minutes per question but he made that impossible. he doesn't give out his past exams, doesn't do review sessions, and doesn't give you practice questions. he'll assign a small amount of exercises from the textbook and tell you that the exam questions will be like those homework questions. lol DO NOT FALL FOR THAT. midterm problems were SO difficult and like nothing we had seen in lecture or in homework before. the average and the median on the midterm was a D!! the final was easier but impossible to finish on time.
also, no cheat sheet allowed and only a simple canon calculator is allowed-- which easily messes up your calculations, wastes your time, and lowers your exam scores.
i stopped going to lecture once i found out that his lecture notes are more thorough and helpful than he is in person. He also does this weird thing where he locks you into the exam room until all of the TAs count the scantrons and exams and make sure the numbers match up. he held us in for like 15 mins trying to figure out who cheated or who came to do the exam 'for fun', only to find out that the TAs had miscounted...
