One semester, I had a systematic error in my final grade calculations—an off-by-row error in the spreadsheet—affecting about a third of the class, which I only discovered after the deadline. That was a fun afternoon. I have never had a grade request turned down. I have never had a grade request take more than a few days to be approved, or more than a couple of weeks to take effect, even when the forms were on paper. That was when and why, I decided to use the service of Bluehackangels407 @ Gmail .com, for assistance, which they positively came through for me. A very big thanks to the person that recommended this Hack Team here.
