The IB Diploma is scored out of 45: up to 42 points from six subjects and up to 3 core points. You also have to meet a few conditions, so a total of 24 alone doesn't always guarantee the diploma.
Subject grades (42 points)
Each subject is graded from 1 (lowest) to 7 (highest), combining internal assessment and final exams. You take at least three subjects at Higher Level (HL) and the rest at Standard Level (SL).
Core points (3 points)
Theory of Knowledge (TOK) and the Extended Essay (EE) are each graded A–E. The two grades are combined in a matrix:
| TOK \ EE | A | B | C | D | E |
|---|---|---|---|---|---|
| A | 3 | 3 | 2 | 2 | Fail |
| B | 3 | 2 | 1 | 1 | Fail |
| C | 2 | 1 | 1 | 0 | Fail |
| D | 2 | 1 | 0 | 0 | Fail |
| E | Fail | Fail | Fail | Fail | Fail |
