CHEM2BL . Pazos S 13 Days Ago

She was extremely rude and condescending to me in lab 3L. Is such a harsh grader and genuinely has no empathy for anyone.

CHEM2BL . Pazos S A Month Ago

i asked my lab TA if i could make up lab/ get online data so that i could take my bio exam due a conflicting schedule, and she said YES, but to ask pazos first. so i did, and she basically told me that it was my fault for making my schedule like that and that i could not skip lab. so i took the L on bio and got a 0 on that bc of lab. bruh.

So incredibly unprofessional. makes ta's grade down and harder, but doesn't give a rubric or examples of how it should be done, just expects students to "know better". Final is a mix of Chem 1a and 1b, but gives no resources. no lecture notes, no practice tests, no review sessions. Final is based on Chem 1a and 1b, even though the course isn't???

Had Pazos for Chem 2AL/BL. She is a complete joke of a professor. Rude, condescending, and doesn't care for her students AT ALL. Besides the down curve, the whole 2BL class was unnecessarily hard because TAs were forced to take points away arbitrarily to keep averages lower. I truly don't understand why this woman is so obsessed with her average.

This class is ridiculous. She's chungus. I actually don't understand why she's still here ... ucsb needs to do better. This is literally GEN CHEM it is not that deep at all. She should go to organic chemistry where being crazy would make sense. Sorry to everyone that has to take lab, it doesn't get better after AL either.

i don't know who hurt her, but she is a hateful and pathetic excuse for a chem professor. she genuinely wants her students to fail, avoid her at all costs.
