There was a course that I have taken before and passed. Like a good pass. I just don't feel like sharing the grade, but it was good. I learned a lot from the class and understood the material well and demonstrated that several ways. A year later I am re-taking the course because it's been a year since I've been in school. I am taking it a different school. If we had to compare the schools... the first school I took the course at is very well known for it's academic rigor... it's a school pretty much everyone has heard of. The second school I am taking it at is also well known... but academic is not what comes to mind, but it's good in academics too. Anyways I'm not doing well on the exams at the second school. I study hard and I am a very hard worker. I enjoy solving physics problems for pure fun and so studying for me doesn't feel like a task or a must do. So I am not sure what is happening? I passed this course once and I am failing the second time? How does that make sense? I haven't even forgotten all the things i've learned. How could i do much worse on the exams now? I don't get what is happening! This has never happened to me before. What should I do? Also the professor is not very approachable and is actually not very good at all. I don't want to go into details, but there must be something on my part that is not good. I personally don't think it's a lack of understanding and the proof is there in my transcript and word of mouth from the prof who taught it to me the first time! Any advice is welcome.
