She goes fast in lectures, but she NEEDS to. It's calculus. If you're still confused or couldn't read the board, GO TO HER OFFICE HOURS.

Wouldn't take again

This is by far the worst class I ever taken. The exams were every 2 weeks, which was absolutely horrendous. By the time you finished one, you were already stressed about the other. The lectures were prerecorded, horrible, had multiple mistakes. Just stay away from this professor, unless you can learn all the material on your own.

You have to be good at self studying to do well in this class. Lectures are so disorganized and all over the place and the professor is impossible to follow. I very quickly learned I wasnt learning anything from lecture and had to find other ways to study. Only teacher Ive ever had whos lecture is completely unlistenable.

The professor seems like a kind person, but that's about it. The pacing of the lectures are not great and you will learn more from the pre-recorded lectures. The organization of the class is awful; materials and homework are scattered among various sites and have different formats. Exams barely test you on the course material and are frequent.

If I could give a 0 I would. There is no way this woman knows any kind of math. She doesnt explain anything and exams are on cbtf. Grading is done awfully. Take Guzmans class only if you hate yourself. Easily the worst teacher I have ever seen so far.

Terrible professor. Is apparently unaware that her lecture hall was full at the beginning of the semester and now only ~10 people go. She teaches one thing, something else appears on the worksheets. Tests are frequent and impossible to do well on if you don't teach yourself. Only choose her if you like to torture yourself.

Insanely hard tests and doesn't know to teach during lecture. Definitely learned more from the Organic Chemistry Tutor on youtube than I did from her. After a 5% curve, the average on a test was a 56. No partial credit on tests or extra credit assignments, even though every student desperately needs them.

The worst class I've taken so far. The only way to get a good grade in this class is curve that's applied to all the exams and final grade, otherwise a large majority of the class would fail. After curves, her exam averages range between 50-70, if that says anything. All the exams are way more difficult than the practice, with no partial credit.

Nice person but definitely has no place teaching Calc 2. It seems like she does everything in her power to make sure we fail. Useless lectures, poor organization, and exams that are unfairly difficult with no partial credit.

To be completely honest, I should have trusted the reviews on here more. I had her for MATH 221 and I had taken AP Calc AB and BC with 3s like most people in this class. She is extremely hard to follow, and I honestly feel you are better off not going to lecture and just doing khan academy and learning in discussion period.

She's a very nice person, but her lectures are incredibly unorganized and hard to follow. I had to basically self-teach on youtube and learn during my discussion period. The tests were also really hard and the practices weren't always reflective of what would be on there. Just a super hard class with a really hard professor tbh.

I don't know a single person who went to lecture... Professor Leonard on Youtube was more helpful. She's a really nice person but her lectures were unorganized. Discussion section was fine. The tests were very hard for being taken on computer with a time constraint and without partial credit. TAs carried. Test averages were around 60 (with curve).

Learned nothing in this class. Tests were not well put together, and way harder and unlike things, we did in discussion and on WebAssign. She is passive-aggressive in emails and doesn't even record her own lecture videos, which were often unhelpful, unorganized, and sometimes just cut out in the middle of problems. Avoid her like the plague.

No doubt her class is extremely hard. But with patient and efforts, you will get more than just A but a wonderful learning experience. Professor Guzman is friendly and approachable. You could always get feedback and ask help from her. Her class is some sort of unorganized and hard to understand so please learn ahead of class.

Her class was the most frustrating and unorganized course I've ever taken. Her recorded lectures were from a different professor that skipped over important theorems/rules. HW was difficult and exams felt virtually impossible. The average for each exam wax extremely low. Unless you've taken Calc BC, I highly don't recommend her class.

I learned a lot! Very kind! I feel that most people did not take the tine to appreciate her class. Please take into consideration that in order to learn anything from a class you can't have a teacher who is not teaching you. This teacher does a great job in delivering the concept and if you are nice
