He doesn't get to actual calc until like week 6 or 7. The lectures are awful, but the nice thing about math classes is that you can learn everything you need to on your own on like kahn academy. I watched his lectures at 3x speed (2x sounded like he was talking like a normal person) just to get the gist of what he wanted us to know specifically.

If you took AP Calc, the beginning of the course will be super easy and review. It lets you see how overly complicated he makes things. But, the final is 50% of the grade and covers the newer material. He's a really a bad lecturer but genuinely a nice person. I liked him but not his teaching. Don't bother going to class, watch yt videos and do CLAS

He is a great professor who knows math well and really cares students. He is extremely patient and helpful especially during office hours. He could be a little bit nervous and serious during lectures, but he is actually pretty kind and friendly. If you really want to learn something about math, definitely go to his office hours.

His lectures were not so good. He confused me a lot. He made the class seem harder than it needed it to be. However, his midterms were do-able. Just not his final. His final was hard. He was really easy on homework. Like only 10 problems every week. Also, sections are mandatory. I think that is all. Oh actually, he was a nice dude.

I dunno why he received such low rating. Nice caring guy. Lectures are actually pretty good, in contrast to what the other rating claimed. Integral itself is a difficult topic, so you may not be able to catch the meaning of the functions and equations during the lectures when you first hear of that. Go to office hours or CLAS if you have questions.

His class was really boring and if it weren't for my previous knowledge on calc then I probably would have flunked. His lectures were hard to sit through and the homework didn't correlate with the lecture most of the time. Also don't expect him to round up any grades such as an 89.8% or higher.

idk why Prof Lopez has such negative reviews, at worst he's a mediocre lecturer. He has alot of positives and I would highly recommend taking him. He drops a lot of stuff and bases quizzes on the hw, which are pretty easy. His office hours are amazing, he knows a lot about the material and explains it in depth. Hes very nice and I def recommend him

uses diction that is much too heavy and causes students to get very confused. Very nice guy, but does not understand how to explain things in a way that students will understand.

Lopez was a so-so lecturer and used a lot of high-versed jargon, which made this course even more difficult than it needed to be. Very difficult final containing challenge questions. However, he's super knowledgeable about math and quite helpful during office hours.

Great Professor.

He CAN'T teach at all. Brings pre-made piece of a paper and copies everything on it. If you ask for help on something he hasn't prepared he won't have the answer. 3 midterms 1 final. I wouldn't have mind the tests if he gave us a practice test that was as hard as the actual test because the practice tests gives you a false sense of security. CLAS!!

I had Lopez for Math 3B and he is hands down the worst math teacher I have ever had in my life. Attending lecture did not help me understand the material, it just made me more confused. He's unable to explain concepts in a concise manner. You're better off learning from CLAS and Khan academy; that's how I got through this class.
