Is this accurate?

I had a 65% in the class. It turned to 64.41 after the final was added, the final is worth 20% of my grade in which I got a 60 on. That made my grade become a 64.41. After she added the final grade, my teacher added one last assignment being worth 65% of my grade in which I got a 80.36% making my final grade a 64.00%.
