I evidently did not have the same experience as many students here did with Professor Aschenbrenner. Though is lectures are based on the textbook, he does an excellent job breaking down concepts and explaining them in a digestible manner. His teaching method, especially in the latter part of the quarter, is heavily focused upon "finding" rules and equations based on theoretical problems and previous theorems (light-weight proofs, in essence). If this is your learning style, as it is mine, you'll do fine.

He assigns two to three lessons of homework per week (depending on the number of lectures), generally totaling in around 15 problems; this is easily doable. Homework is graded fairly and is not exceptionally difficult.

Two midterms are given, the first of which the class average was around 58, and the second around 78. His midterms tend to drift towards conceptual questions rather than practical ones, but are fair nonetheless.

I interacted with Professor Aschenbrenner only minimally outside of class. In lecture, he remains lighthearted and cracks jokes now and then. He seems nice and helpful enough during his office hours.

He is very strict about his homework policy--late is not accepted. Don't try to turn things in late and you won't have a problem.

While he does have a German accent, it is not heavy, nor is it difficult to understand.

All-in-all, this class is quite straightforward, particularly if you have previously taken AP Calculus. I am really not sure where all of these complaints are coming from.

HE COMPLETELY SUX !! HE IS ALSO MEAN ! DONT TAKE HIM!!!

Aschenbrenner was a terrible teacher!! I had taken Calculus in high school and managed the class. When in sat in his class every day i could not stand his teaching he just read the book to us and it was a complete waste of 50 mins. Tips to succeed in his class are to not go to his class, learn stuff by yourself. He seemed nice though but i did not want to approach him because i was afraid his office hours might be as boring as his lectures. Not a quality professor take this class if you are an engineer or someone naturally gifted in math. He will not improve your mathematical skills

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.

He's a halfway decent teacher, but then again I had already taken calculus in high school so I knew a lot of the stuff going into the class. His heavy accent can be a bit distracting and difficult to understand at times, but it's really not a big deal. The quality of your TA is probably the most important part of this class, as the TA is the one that's going to really answer questions and explain the material in-depth. If you're adequate at teaching yourself from the book and you practice, practice, practice before the tests, then you should be fine.

He is an awesome guy! Really funny. Class would be hard if you haven't had any previous experience, but reading the book and asking questions would really help. Two midterms, one final, and weekly homework asg. I really recommend that you take him if you have a chance. He's a really funny guy.
