A guide, not your official GPA. Your school's transcript and its own point values decide.
Grade points and extra points
Default: A = 4, B = 3, C = 2, D = 1, F = 0, as in the College Board's 4.0 table, with 0.3 steps for plus and minus. The plus and minus values, the A+ value and the Honors and AP extra points all differ by school, and there is no national rule. Your school's own values decide your GPA. Change any number to match them.
| Letter | Grade points |

| A+ | |

| A- | |
| B+ | |
| B | |
| B- | |
| C+ | |
| C | |

How GPA is worked out
Each letter grade has a number of grade points: on the usual 4.0 scale an A is 4, a B is 3, a C is 2, a D is 1 and an F is 0. Multiply each course's points by its credits, add them up, and divide by the total credits. Six one-credit courses graded A, A−, B+, B, A and C+ give 4 + 3.7 + 3.3 + 3 + 4 + 2.3 = 20.3, and 20.3 ÷ 6 = 3.38.
Weighted GPA
Many high schools give extra points for harder courses. With the defaults here, Honors adds 0.5 and AP or IB adds 1, so an A in an AP course counts as 5. In the example that adds 1 + 0.5, giving 21.8 ÷ 6 = 3.63. The extra points are never added to an F. Your school sets these numbers, and colleges often take the extra points out again and work out their own figure.
Credits
High school courses are often 1 credit, or 0.5 for a half-year course. College courses use credit hours, such as 3 or 4. A course with more credits moves the GPA more.
Cumulative GPA
To add this term to earlier ones, type your GPA so far and the credits it covers. The page weights each by its credits. It uses the weighted figure when there are extra points, so give it a GPA so far of the same kind.
