How scores are worked out
A problem is its best submission, a section is the average of its problems, and the score is the sections weighted.

A problem
A problem's score is the best of the candidate's submissions made before the clock ran out, out of 100. Within it, each requirement carries a share of the marks; a few are informational and carry none.
A section
A section's score is the average of its problems' scores. A problem the candidate never attempted counts as zero.
The overall score
The overall score is the weighted average of the sections — each section's score times its weight, divided by the total of the weights — rounded to a whole number. The candidate passes when it is at or above the pass mark. For example:
| Section | Score | Weight |
|---|---|---|
| Spatial Analysis | 80 | 3 |
| Spatial SQL | 60 | 1 |
| Overall | (80 × 3 + 60 × 1) ÷ 4 = 75 |
With a pass mark of 70, that candidate passes.
Why the best submission counts
During a sitting a candidate can submit as often as they like, and sees only that each answer was recorded. Counting the best means trying again never costs them, and a late slip does not undo an earlier right answer.
