Second semester grades

Does anyone know of Ohio State’s policy regarding second semester grades? As of now I have two C’s (which is extremely uncommon for me as I have never had C’s) due to the rigor of my AP European History course and mathematical course. Aside from that, I have all A’s. I have been assured that my C will become a B next quarter, averaging a B. This will be normal for my mathematics course (Pre-Calc), however AP Euro will be difficult to improve. I have not yet been accepted, I am a deferred applicant, and I hope this does not impact my decision as of now. I have heard they are mostly lenient on the grades for second semester (if they are within standards), however I am seeking assurance and help from you all.
