Deviation from predicted grades

I got accepted into Purdue earlier this year, and had just my finals left. However, my math exam was terribly tough. Im worried if too much deviation from my predicted might ruin my provisional admission. Im expecting 80-85+ and my predicted is 95.

Also my physics predicted is 91 but my worst case scenario is ~87

My chemistry would be 95 and my predicted is 91, and eng and cs will be 98 each, with predicted being 92 and 95 each
