She is really nice to students and helpful. Lectures are well organized, and proofs flow fluently. She gives motivations and time for students to actually think about the theorems. Will definitely take classes with her again!Rate My Professors ↗

Original student reviews · all captured dates
Her English is really bad, we had lecture attendance of 40% because somehow she made the concepts more complicated by explaining them as poorly and incompletely as she did. No curve. She just kind of spills the notes onto the blackboard for the whole lecture and doesn't answer/understand questions well. She just doesn't really speak english guys.Rate My Professors ↗
Tests are extremely straightforward. Easy problems are on the exams with no surprise conceptsRate My Professors ↗
Math major, have taken a lot of math courses. WORST EXPERIENCE EVER!!! Shows no respect in office hours. Hardly ever reply emails. Worst professor in Math department for unable/unwilling to explain the materials or any question. Rude and arrogant.Rate My Professors ↗
Keeps her back to the class the entire time and just keeps writing, with no explanation. I wouldn't take 319 if I did it again, 320 is much more doable and applicable. She whispers and has a heavy accent.Rate My Professors ↗
Absolutely terrible professor. She does not know how to explain the material or answer your questions. She does not explain what she writes down and it is extremely difficult to understand her. AVOID. The worst teacher I've ever had. Hands downRate My Professors ↗
