One bad grade vs upward trend

So I got accpeted to UW last Saturday and I was prompted to self-report my mid-year grades. This year I got more A’s than I expected (e.g calculus from B to A+).

HOWEVER… the problem is I failed Chinese in all class assessments and finally got a C. Now I’m worried that my admission will be revoked - I got an A for the past two years. The reason my grades declined, long story short, was my Chinese teacher unreasonablely marked the paper (the said marking was not on the marking scheme). I tried to seek resolution but failed, and eventually failed with a 8-mark difference.

So… I would like to ask if this one grade is the reason for revoking admission. I hope not, since I just did my final exam and I think I will have a good shot this time!

Don’t worry.
