Well. To be honest with y'all, those bad and good reviews of this prof, I can only say half of them are correct and half are not. What I want to discuss here is not how hard or easy to get an A in his class, what I want to talk about is if this prof is really helping you and efficiently teaching you in your academic life or not. Unfortunately, the answer is NO. He does not give you homework at all, so when you are preparing for your test, there would not be a lot of material you can review. Little workload will make you not remember a single term after years. If you plan to get a job in the future that's related to the professional knowledge you would learn in your major classes, DO NOT TAKE THIS PROF'S CLASS. If you are taking this class for fun, then whatever.

As a transfer student, this was the first Econ course I take at UCLA(I took Econ11 at another University). I was nervous about this course especially when seeing the previous reviews. However, the professor truly understand everything and he is so neat and clear about explaining concepts. Sometimes I am amazed by the way he solve problems as his brain is moving so fast.

The course has 2 midterm(higher midterm 30% + lower midterm) and 1 final (50%), the median is around a 75 but he does gives a very genrous curve so the median student will receive a B or B+. Make sure to do every single practice problem before his tests(including the ones on lecture slides), no homework and no problem sets weekly, but please don't slack off and don't wait everything until the end. His office hours is also helpful. I got A by doing his practive problems and understand how to do them without looking at the solutions and going to his office hours when needed.
His exams are fair and doable. If you really interested in econ, he is the right choice, you will learn a lot.

Do not take this class!

The grade is 20 percent for the lowest midterm, 30 percent for the highest midterm and 50 for the final. The tests aren't too tough themselves, but they are graded very, very harshly. He is very unforgiving and there isn't much practice. He gives us a few discussion sheets to practice on, and he shows the midterms from the year before (which were much easier than the ones that we had). The final and midterm review sheets were kind of helpful, but not too much. He is a very mediocre professor, and lectures are very boring.

If the practice questions were more like exam questions it would have been reasonable to do well. The only redeeming quality about him is the curve. I got about 5 percent higher than I would have without the curve.

Until now, I think Professor Vogel is pretty good. His slides are clear and organized. His midterm one was easy, and his discussion sessions and homework provided some useful practice questions for this exam. His midterm two is tricky and different from the questions posted on CCLE, but if you read his slides very carefully, you can make it.
Besides, my TA Miss Ariadna is really nice, helpful and knowledgeable. I will recommend my friends to take her discussion.

Okay so the person who wrote the review before this one is clearly bitter about something because let me tell you something this guy is one of the good professors in the Econ department.

He gives practice questions, homework and discussion questions and gives us all his slides. While sometimes his explanations are slightly complicated if/when you read through them again at home it makes sense. He also does try to relate it to simpler examples.

I would recommend Vogel.

Easily the best professor I've ever had. He's great at clarifying concepts, makes the class engaging, cares about student learning, and has straightforward exams. Definitely recommend taking his course.

Vogel is, overall, a good professor. He's very clear during lectures, uploads all the slides, and gives students plenty of resources to succeed in the class. One of his TAs (Ariadna) is amazing, and possibly the best TA I have ever had at UCLA. However, he was not a perfect professor and has many policies that may strike a wrong chord with some students. So read this and consider the flaws of the class if you need to take Econ 101 with him. And if you didn't do too well, I understand where you're coming from, but don't just brush off this review and others because they don't say what you want to see.

I will reflect the sentiment that having Midterm 2 after Thanksgiving break was pretty awful. Additionally, I feel like there was too big a disparity between the difficulty of the first midterm and the two follow-up exams, where the latter two were significantly more difficult to prepare for (although he repeated a question from MT1 on the final). I never really found a problem with his attitude but he does sometimes take jabs at UCLA through his homework questions. I also don't really like the fact that his exams are only a few questions, which can make them unforgiving if you don't know a concept. These are what I would say are the flaws of his class.

But to make up for it, there's plenty of partial credit (edit: yes, you do get partial credit. The second midterm grading was suspect, but overall you will get points for having part of the solution. Not considering boundary solutions is huge; half the work on a given problem that has them is on determining the conditions when the boundary solutions apply) that you can get for setting up the problem in a reasonable way. There's even the possibility of him overscoring one of the problems if you put in extra information about the solution, though I'm not sure if he still does this. Although his exams are short yet difficult, he includes extra problems on the homework to study from and gives solid preparation problems for both midterms and the final. His final review problems were actually very close to what we got on the actual final.

Overall, the class was fair, and Vogel himself is a good lecturer, but if you fall behind, it can be very unforgiving. I was ill-prepared for Midterm 2 and got a 56/100. However, there is always a chance for a comeback if you improve enough, as I still ended up with an A in the class after doing well on the final. If you take this class and don't do too well in the beginning, it's not the end of the world.

Way harder than Econ11 with Surro in my op, mostly because with Vogel you will definitely be teaching yourself the material 95% of the time. Lectures and discussions I felt like I genuinely didn't gain anything from, and knew that I would need to teach myself later what concepts he was teaching, because they were so abstract. The practice problems from previous exams are the only way you will be able to study for exams, so make sure you understand the intuition and how to best approach previous problems.

Do practice tests; they are your lifeline. Do them over and over and over again until you memorize the approach and can recite the answer just looking at the problems. There are no other problem sets so those past exams are all you can rely on.

This class is so egregiously dogshit. This is the worst class I've taken at UCLA by far and I truly hope Vogel improves the way he runs this class. Lectures are vague and needlessly wordy and hung up on 1-2 practice problems, exams are INSANELY hard, Vogel himself is snarky and refuses to help during office hours, and discussions are COMICALLY useless

Vogel is by far the worst teacher I've had at UCLA. He spends lectures explaining incredibly abstract topics then discusses 1 practice problem for 45 minutes with 0 regard to prepping for exam materials. When reading slides, you can essentially ignore 75% of the slides at the back half since they are focused on random practice problems unrelated to exams. It's not a variety either (which would at least be something), it's like 1 problem that he spends weeks on

I tried going to office hours and he is incredibly snarky, makes fun of the questions kids ask, and refuses to elaborate when students are CLEARLY confused. I really dk what this stems from, because a student will go him distressed needing help and he will essentially brush them off. Exam averages are ass which shows his genius strategy doesn't work (check other reviews for how bad grades are in this class), its like a 75% and 60% aveerage for the midterms and there is NOTHING else that goes into your grade. Vogel: GIVE SOME HOMEWORKS, PROJECTS, OR SOMETHING SO I DON'T HAVE TO DEAL WITH THE HORRID WAY YOU WRITE EXAMS

Discussions are useless, do not attend. I went for 10 weeks and truly learned nothing it was incredible.

I genuinely hope Vogel does some self reflection after putting me through a class so aggressively DOGSHIT. I learned nothing, and I'm glad to never see this man or his goddamn 2-bullet point calculus-filled slides ever again
