IB Admission for Princeton

<p>Princeton says, for the fall semester, that it will extend a "conditional offer of acceptance" until successful completion of senior year. Basically they will rescind the offer if you do not graduate or if your grades drop significantly between January and June. Now IB exams are written in May and the results only come out in July. Right now I've been predicted a 45, but in a worst case scenario I think I might drop 4-5 points in the actual results. If I do get into Princeton, is this considered a significant drop? And will they even take the final IB results into account? After all, they do come out in July which is beyond the month range Princeton has stipulated. I know this sounds kind of pathetic but getting into Princeton is really important to me.
Any help would be greatly appreciated!</p>
