The highest possible

Average of the compulsory subjects: 5.0000
Added by the optional subject: —
Divided by: 7

The fourth-subject rule is what most calculators get wrong: its full points are not added — only the part above 2.00 — and it does not increase the number of subjects divided by. An A+ in the optional subject therefore adds 3 points, not 5, before the division. And once the bonus takes the GPA past 5.00 it stops at 5.00.

This is an aid — the board's published result is what counts. The mark-to-grade bands are the standard ones; where a particular subject, a practical component or a board instruction differs, go by the marksheet.
