<p>Even if they were to use a +/- scale for the GPA recalculation, I’ve never heard of a school treating an A+ any different than an A. The logic is that nothing (in an unweighted system) can be higher than a 4 -which signifies an A. Giving 4.3 for an A+ goes against this policy.
As others have said, don’t ficus so much on your grades. Stanford and the other top tier schools are looking for unique people who will make a difference: not just straight A students. For example, I have a 3.8/4.5 ish GPA and was deferred by Stanford REA while at least 3 kids with higher GPAs (3.97/4.7, 4.0/4.8) and class ranks got rejected. While I had done a lot of unique ECs they really just had high numbers.</p>
