Definitely not by my choice. So so boring. So hard to sit through lectures.

Turned in first homework late because I mixed up the time and she was nice and excused it. Graded project and homework easily, but exams were decently hard. Lots of extra credit if you just go to class.

Homework was similar to the problems in class, she offered up to 3% extra credit for going to lecture, and the group project was relatively easy. There was a lack of guidance on preparing for the exams and the group project as the expectations weren't always clear.","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":"UmF0aW5nLTM2Nzg2Mzkx","source_instructor_id":"rmp:2592851","instructor_name":"Tina Xu","course_label":"ISYE312","course_id":"ISYE 312","course_uid":"course_5b7e840b49cedb60a91edc99","review_date":"2022-11-06 21:55:28 +0000 UTC","comment":"I've had Tina Xu for 312, 313, and 512. Every single class is exactly the same: reading boring slides in a monotone voice. The slides are never organized, and are rarely helpful if you miss something in class. She does not enjoy teaching, and it shows in her lack of energy each and every lecture. Luckily, exams and homework are not too hard.","source_url":"https://www.ratemyprofessors.com/professor/2592851","quality_rating":2.0,"difficulty_rating":2.0}]
