Reviews of professor Dinah Espineli

Rating: 1.0/5, difficulty: 4.0/5
If you do not have a natural understanding to chem or didn't take it before in hs, this will be a tough course. I cannot count the number of times I came up to her for help and she had a "you should know this already" mentality instead of helping. One of the rare profs I have ever taken that doesn't want her students to learn, just memorize info

Doesn't respond/acknowledge messages from students. Doesn't help students, refers to tutoring. Only cares about reading lectures and not making sure students grasp the concept/material. Would not take her again.

Chemistry is difficult subject so you really need to put in the effort and time to really study and understand. Her worksheets can really make or break your grade, along with lab reports. Her class is relatively straight forward, but she does move quite fast and her explanations can be a little convoluted. She does provide extra credit.

Lectures are not bad, but does not provide much practice for exams. Exams do not reflect class work and each MCQ is worth 3-3.5 pts, which can bring your grade down a lot. She does not go over exams/homework, which almost always have mistakes. Ignores student emails and is rude if you ask clarifying questions.

Chemistry is not an easy subject, and she makes it worse. She focuses too much on people who cheat, and I think that's why she makes her exams extremely difficult. This is unfortunate for those who we really want to learn chemistry. She is a reasonable in person but terrible during online classes.
