I am taking an upper division chemistry class and we just had our first exam. Some students had the old exam (from last semester) that the professor did not provide. Apparently the exam we took this week was identical to the old exam. The professor is the same as the last semester. The professor however didn't let students keep the exam last semester. He didn't even post the answer keys or go over the exam. He just let the students see it once in class (or can review during office hour). However, some student(s) last semester took the pictures of exam behind his back and sent them to some students who are in the same class as me. I am so annoyed that 1) some student from last semester was so disrespectful that he/she took the pictures and 2) the professor reused the same exam. The professor tried to prevent the exam from spreading but didn't work haha... He curves each exam and I'm just so anxious if a lot of students actually knew the answers to the exam beforehand and if I did below the average. Would you do anything about this?
