GPA Calculation?

<p>On the results/chances threads where people post their stats, how is GPA being calculated? Most threads ask for GPA out of 4.0, but I'm asking how they convert letters to numbers. On that scale, does an A- exist and if it does is it worth less than an A?</p>

<p>Thanks very much for your help!
I am aware that this may not be the best place to ask this.</p>

<p>When your high school sends your transcript to colleges, they also send a “profile” which is a rubric for how your school’s grading system works. Admissions uses each individual high school profile to decode a student’s GPA. If you haven’t seen your high school’s profile, ask your GC for a copy. For example, here’s Boston Latin’s high school profile: <a href=“http://www.bls.org/ourpages/auto/2013/5/24/55204166/2014-15%20BLS%20Profile.pdf”>http://www.bls.org/ourpages/auto/2013/5/24/55204166/2014-15%20BLS%20Profile.pdf&lt;/a&gt;. </p>

<p>FWIW: Who knows how students on chance threads are calculating their GPA. My guess is that many of them are including ALL their courses, however some colleges recalculate a student’s GPA using only the core courses of math, english, science, social studies and foreign language while disregarding easier classes like chorus, theater, art, music, dance, gym and health. Unfortunately, most colleges (including Harvard) are not forthcoming about how they calculate a student’s GPA.
