TLDR: Incoherent lectures, inaccurate notes/practice problems, slow grading, and poor commuication.

She's nice enough, but honestly, it's just gotten too ridiculous. Her lectures don't make sense, and the notes she uploads often have mistakes within them, and even if they don't, it's still hard to understand due to how unorganized they are. The only upside is the videos she uploads to the media gallery (from another professor). This wouldn't be horrible if not for the absurdly difficult homework assignments and exams that the videos (again, that she doesn't make) and lectures simply don't prepare you for. Studying for exams is also a nightmare. The practice problems she uploads are not only full of errors and typos, but also formatted inconsistently. Multiple C++ compilers give different answers compared to the ones she gives in her answer key. She also doesn't communicate well with students; many questions you ask in person are met with "I don't know" or "I'll figure it out later," and she rarely answers questions on Piazza.

The last issue I have is that she also takes forever to grade. To be fair, this is definitely more of a funding issue, but it still sucks waiting forever for any homework to be graded. It took almost a month for the first midterm to come back.

She struggles to teach the material effectively, and her lecture notes are often disorganized and difficult to follow. Her coding demonstrations frequently contain errors, and she does not correct them in real time, leaving students confused about what the correct approach should be. I felt that I learned very little from the lectures and had to rely heavily on Media Gallery videos from other instructors to understand the content.

She is even not a professor! She is a postdoc student. I wouldn't expect that the funds are so limited that the school has to ask a PHD student to give a lecture.

1.She doesn't post her lecture notes or videos
2.Her lectures are not clear and she never designs and arranges the notes. She just randomly writes sth down on the whiteboard in a chaotic way.
3.She makes mistakes during her lectures frequently, saying "I will figure it out later" and then nothing follows.
4.The HW workload is overwhelming.
5.The exams are challenging. She said the reason was that a difficult test can make us listen to lectures more carefully in the future. What? This is totally bullying students! She can totally figure out why we can't pay attention to her lectures if she spends some time thinking about the quality of her lectures and notes.
6.If you ever have a classmate who after exams loves to write sth chaotically on scratch paper and explain to you in a way that only they can understand and repeat what they say until feeling they understand themselves, you will have the same feeling on this professor.

In one sentence: it is the school's fiscal failure, not this professor's fault. She is also a passionate student who dedicatedly pursues her interest. It's the schools' choice that compels her to lecture undergraduates. What the school does is eroding the value of our substantial tuition.
