For me, Professor Aschenbrenner was sub-par. Going into the class with previous calculus experience, I failed the first midterm. Realizing his lectures were useless in terms of the tests, homework, and understanding, I never again attended a lecture aside from discussion, which was the only thing worthwhile. By going to the TAs office hours and discussion (highly recommend matt lane), I proceeded to get an A on the second midterm and the final. Traditionally professors are supposed to teach, but if you're looking for this don't take Aschenbrenner. I did get extra sleep though, so I guess in a way it wasn't so bad

Well first of all I never took calculus in high school; so, to come into Aschenbrenner's class was one of the worst experiences of my life. He is a horrible teacher that is hard to understand and he pretty much copy pastes from. Plus, if taken first quarter you're taking it with all the math and engineering majors who destroy any curve that might have existed. If you can do not take him.

Aschenbrenner is a nice guy, but can't teach for his life.
He made jokes in lecture and seemed approachable. I already took calculus in highschool, but his class was still extremely hard for me. You have to learn everything on your own. I advise you to sign up for covel tutoring if your taking his class. He pretty much just copies whats in the textbook onto the board. The fact that you're taking math with engineers, chem majors, and international students also doesn't help.

Just know that there is pretty much NO CURVE.
Someone is bound to get 100, and a group of people will get 80% and higher.

Goodluck.

The worst professor I ever had in UCLA.. The only comment I can give him is OMG.
Heavy accent, not willing to answer your question in his office hour. I mean he will only tell you how to do it, but not write on the board. If I know how to do it, why would I go to his office hour to ask him?
No worth to take him.

Not really a great professor. He's funny at times... After first midterm, I rarely showed up to class except Fridays to turn in homework. If you know a bit of calculus and you study/ review you'll be fine since you know that the material will be based on the homework he gives you. His tests are doable, you can't fail if you actually studied. As long as you study you should be fine.

Aschenbrenner is not the greatest lecturer. In class, he focuses too much on proving and deriving formulas and concepts, and doesn't do examples that help learn. When he does do examples, they are often too easy and don't show harder concepts.

I got a A focusing solely on my TA and self-studying, by reading the textbook and watching online videos about concepts. If you do that, you will be solid. If you simply attend class and study class notes, you don't do well.

His exams are relatively straight forward, but he does throw some curveballs that end up being like worth like 20% of the exam. Know the material well. The final was difficult. It wasn't straightforward and was complex. The mean was a 57%.

Overall, I would take this guy for 31B again. His exams are not that bad, and if you study properly, such as watching videos online, you will do great. His problems are of the same difficulty you see in videos. The final was much more difficult, but it is curved, so getting an A is not hard.

Aschenbrenner is a good guy and teaches a manageable class. The course breakdown is as follows:

5% HW (due at the beginning of friday lecture, he turned away people who came in like 10 min late)
5% Quizzes (1 question from the previous weeks HW done at the end of section)
25% Midterm 1 (7 questions)
25% Midterm 2 (7 questions)
40% Final (12 questions)

Some questions on his tests were a little tricky, but the problems were never that long or too difficult. I skipped a lot of lecture, as they are not really necessary for learning as long as you do the homework.

I found a youtube page that has almost all of the sections covered in an expedited lecture (from the same textbook, Rogawski) here:

Here is a link to the course web page with all the info about the class, including the syllabus:

Good luck on this class! It's not easy but very much doable.

I went to his office hours and he told me to look in a different part of the book to figure it out. While this does push me as a student, I already wasnt a fan of his ridiculously boring lectures with rough handwriting and an accent that is kinda difficult to understand. Luckily my TA was great (get Keneda if you can) and was quick to help with any questions. Aschenbrenner also teaches DIRECTLY out of the book (even the examples he uses), which makes it okay to miss lecture. I actually learned more from the book then I did from the professor. Basically he sucks so unless there is a worse professor for the course, avoid him.

The lectures are dry (as almost all math lectures are to me), and the professor is very heavy on the theories. He spends most of the time explaining how formulas are derived, which is interesting but doesn't help much with the homework. Just going to the lectures definitely isn't going to get you a good grade. Some things that helped me:
1) Going to discussion sections: the weekly quizzes were ridiculously easy, but they kept me studying. My TA, Kwon, was really helpful--during the review sessions, he would go over especially difficult problems that are similar to the ones on the exams.
2) Test bank: Aschenbrenner gives out the solutions right after you turn in each exam, and you can easily find previous exams (which gave you an idea of what to expect) at the test bank.
3) Practice problems from the textbook: solutions to the textbook are available online, use them to check your homework. If you don't know what you did wrong and why, you will just repeat your mistakes on the exams.

Overall, this class wasn't as difficult as I expected (while I definitely did put in extra work). It does help to have a solid foundation, like being familiar with all the basic calculus properties. For reference, I took Calc AB in high school and got a 5 on the AP exam. The quarter system schedule is still rushed, but some topics from Calc BC (vectors) aren't even covered in this class, so don't stress out too much--the class is definitely doable.
