You can tell he cares about the material learn and I actually learned a lot. You do have to put in some effort to really understand and get the concepts but the quizzes and assignments are easy if you go to class and follow the demonstrations in class.","source_url":"https://www.ratemyprofessors.com/professor/3112044","quality_rating":5.0,"difficulty_rating":2.0},{"observed_at":"2026-09-07 15:58:42.161332+00:00","run_id":"20260907T155543-ce3781c4","source_review_id":"UmF0aW5nLTQxNTE5MzUw","source_instructor_id":"rmp:3112044","instructor_name":"Xiang Zheng","course_label":"LIS407","course_id":"LIS 407","course_uid":"course_26a3253bb559893e7f2e983f","review_date":"2025-07-23 17:46:06 +0000 UTC","comment":"Good prof overall. His lectures weren't amazing or anything, but they got the job done. Would stay after class to help students/answer questions basically every time. Seems like a nice guy. Class was easy if you do your HW on time.L","source_url":"https://www.ratemyprofessors.com/professor/3112044","quality_rating":4.0,"difficulty_rating":1.0}]
