I had the worse experiences while attending BYU-I. I gave all my time and all of my into hours of studying. Yet, I made D's and F's. I finally went to a classmate and asked her if we could compare answers. She had the exact same answers as I did and she got A's. I went to the professor and asked him why that was the case and if I could do make up work to help save my grade and GPA. He said he doesn't grade then, the student teachers do and that was my final grade. I tried contacting the dean but could never get in touch. I tried to make friends but everyone is fake and self centered.
Why do students run the school? I never saw or spoke to someone older than 25 years old. Trying to get my transcripts was a joke. Trying to figure out what do to about my grades didn't matter to them. Thanks BYU-I for messing up my GPA!
