<p>As seen in a recent email I received it says, i must send in my final transcript as soon as it is available, in any case could you not get in, if your grades decreased. Because my science grade decreased by half a letter grade.Has there been cases of people not getting in after they already got in and signed the contract?</p>
<p>I don’t think a small decrease is a major deterent, it’s only if you clearly bomb out after getting accepted that they reserve the right to rescind your acceptance. This is common with colleges, too, to combat senioritis/“spring fever.” I’d say you have nothing to worry about, but if you have a justification you want to share, go ahead and contact your original AO.</p>
