I’m a sophomore and my grades are normally high A’s but my Mandarin Chinese teacher didn’t put in my assignment before the end of the quarter and now I have an 83. All of my other grades are 109, 101, 102, 95, and 88. Will this affect my yearly grades?
As long as you raise your grade to an A by the end of the semester it won’t show up on your transcript. Also, at least in the high school I went to, teachers could change grades after the semester ends. If your teacher really did just forget to put in an assignment, just ask them to fix the problem for you. There’s no reason why you should be given a consequence if you did the work.
No the grade technically won’t show up on a transcript… But it WILL change your grade, since all grades are usually averaged together. But no, one 83 isn’t gonna be the dealbreaker
This grade won’t hurt you (although the three grades over 100 are kind of suspicious 
), but you should be able to get it fixed if it was just a bookkeeping mistake on the teacher’s part.
