<p>dobrowski, I’m not sure I’ve seen an official version of how USC re-calculates HS GPAs (although I’d really like to see that if anyone here knows). I do know they state they use all grades from years 9-11, including all electives and even PE, and they use them unweighted. They do not use plusses or minuses either. </p>
<p>They have a separate system to account for academic rigor depending on a) the reputation of the sending school, b) the number of honors/AP/IB classes taken considering how many of those advanced courses may have been offered at a particular high school, and possibly c) the box checked off by your GC indicating how rigorous your course selection was when compared with others at your school.</p>
