Her grading is clear, and the exams are exactly what she outlines they will be. While lectures can be dull and include unnecessary information, Tina is both intelligent and likeable. This course is a very easy A if you actually study for the exams and spend a little bit of time on the HW.","source_url":"https://www.ratemyprofessors.com/professor/2592851","quality_rating":4.0,"difficulty_rating":2.0},{"observed_at":"2026-09-07 16:00:40.429510+00:00","run_id":"20260907T155543-ce3781c4","source_review_id":"UmF0aW5nLTM5MDE0NTUx","source_instructor_id":"rmp:2592851","instructor_name":"Tina Xu","course_label":"ISYE412","course_id":"ISYE 412","course_uid":"course_4e8831b837f359daa4b2cadc","review_date":"2024-03-01 03:45:17 +0000 UTC","comment":"Professor Xu is a very nice person. She does example problems in every lecture to illustrate the concepts. You will have a weekly HW, about 4 to 5 questions that perfectly cover the lecture material. In addition, she offers a 3% extra credit onto your overall grade. If you attend lectures regularly and do the HW, this class is an easy A for you.

Tina is so sweet, and from my limited interactions with her seems to be a great person. With that said, her lectures are beyond boring and while she does do several in-class examples, which are beneficial, her handwriting is very difficult to read, causing these examples to often be difficult to understand.

The content in these classes is quite dry, but it makes it harder that the slides are basically a wall of text and she reads off them (like in the other review). Not interesting as no real-life examples are explained well or even differently when someone asks for clarification. Memorizing the stuff may help for the test","source_url":"https://www.ratemyprofessors.com/professor/2592851","quality_rating":1.0,"difficulty_rating":3.0},{"observed_at":"2026-09-07 16:00:40.429510+00:00","run_id":"20260907T155543-ce3781c4","source_review_id":"UmF0aW5nLTM2NjQ3Njk2","source_instructor_id":"rmp:2592851","instructor_name":"Tina Xu","course_label":"ISYE412","course_id":"ISYE 412","course_uid":"course_4e8831b837f359daa4b2cadc","review_date":"2022-09-17 19:27:11 +0000 UTC","comment":"Took her for 412 and 512. She just reads slides (which are terrible). She does handwritten examples in class - these are pretty useless since her handwriting is not legible. She doesn't seek to understand when you are confused - instead, she seems irritated or answers your questions before you are done explaining your confusion/questions.
