Why I Fail Test

I am writing this letter to tell you because I think you should allow me to do a redo on a test so I can achieve a higher mark than I previously have. With that mark I can pass the course and be successful. You should give me this opportunity because firstly, I need a higher mark in the class so I can pass. I have a 43 present in the class right now and I need at least a 50 percentage to pass the course if you let me do this retest I can hopefully score a higher mark than the one I had previously to bump my mark a little to pass this course. To be honest, my goal is to get higher than 55 which is kind of impossible, but I will try my best on the exam to get a mark that I want. Secondly, I don’t want to fail this course because if I fail, it will go on my transcript.
Plus, this is an open course it is counted towards my average, so it will drop my average if I fail, and universities have a certain requirement to be met to be anccepted to that university. I need this credit because after high school, I want to go into business and become a business man and run a business it will be a asset to have this course. Lastly, I need this chance because I was on vacation and due to that I missed quite a bit of work which put me back and also that was in the beginning so it was the basis of the course. Going on vacation and not catching up was my fault because I could have asked for extra help or even catch up on the notes/stuff I had missed. Due to my vacation, I was quite weak in this course. I just need to have one last opportunity to boost my mark, which I for sure you will try my best
