How are GPA's calculated???

Of course… everybody knows that A - 4, B-3, and C - 2. However, would an F be a 1? Or does the admissions committee place D -1? if so, then what is the numberic average that differentiates between a C and a D.

<p>Edit:: i'm talking of raw gpas attained from raw numerical averages which excludes all honors and ap weightings. I also would like to add a reason for asking this question. In my state, there are private schools and public schools in some counties that go by the system of 4,3,2, and 0 - meaning a, b, c, and f. There are other counties going by 4,3,2,1,0-a,b,c,d,and f. if this is so in one state, i assume it will perhaps be like this in many other states. This is the fact that makes me curious when i see average gpas in us news rankings. thanks in advance if u have posted/will be posting a reply.</p>

<p>The standard is:
A = 4
B = 3
C = 2
D = 1
F = 0</p>

<p>If you go to a school that's weighted, then add one to A, B, and C, but not to D and F.</p>

<p>wait... are you saying that all colleges use the standard system of weighting like you mentioned... or is the system only present in YOUR high school...???</p>

<p>Becuase the post was on a web site tailored to high school students, I figured that he was asking for the standard "high school" way of calculating GPA's (he also said "excludes all honors and ap weightings", and colleges don't have AP classes).
However, many colleges differ in that they allow for + and - to be attached to a letter grade. In this case, you would add or subract 1/3 (or about 0.33) from whatever point value the grade was (a B- would be 2.67, while an A+ would be 4.33). Some colleges don't give A+ grades. Some colleges don't give + or - at all. With colleges, it differs much more than with high schools.</p>

<p>Yeah, I'm also interested in how it works. Should you exclude all honor/AP classes when calculating GPA to apply for college or?</p>

<p>I applied to the UCs-- including Berkeley & UCLA; University of Michigan-Ann Arbor; University of Washington; and the University of Pennsylvania.</p>

<p>What happened on those applications was I posted my grades, not weighting honors or AP courses on them because they ask you to list your course and tell them if it is honors/AP.</p>

<p>Thus when you post your GPA you use the UNWEIGHTED GPA because the college itself will take into account your honors/AP courses.</p>

<p>Actually,I believe, the college applications didn't even ask for your GPA, just your letter grade and the course name. The school itself figures out your GPA.</p>

<p>But if you're asking specifically about HOW GPAs are calculated, the basic rule is:
A=4
B=3
C=2
D=1
F=0</p>

<p>Sometimes schools calculate minuses as well and thus:
A=4
A- = 3.7
B+ = 3.3
B= 3.0
B- = 2.7</p>

<p>And etc. However, that's how they calculate your GPA once you are studying at Berkeley anyway.</p>

<p>When they calculate your GPA when you apply, they disregard the minuses and pluses. Thus they ask you for your whole letter grade. You do not calculate your GPA yourself.</p>
