<p>There are two ways to work our your GPA. @cofbrien detailed one of them.
The second one (used by the UC system for admissions, among others) is more forgiving for those with lots of A-s, B-s, etc
A (+/-) = 4.0
B (+/-) = 3.0
C (+/-) = 2.0
D (+/-) = 1.0
E/F (+/-) = 0
To weight this GPA add one point to each grade (AP, IB, and honors classes only)
A (+/-) = 5.0
B (+/-) = 4.0
C (+/-) = 3.0
D (+/-) = 2.0
E/F (+/-) = 1.0</p>
