SUSL marks to a fixed table. With this many tiers, the difference between two adjacent letters is small enough that rounding matters. A+ needs 85% and above, and that threshold does not move with the strength of your cohort. Belihuloya, 1995.
The table runs to 12 grades. D earns 1 point and nothing below it earns anything. Its band opens at 25 to 29.99%.
One thing SUSL does not publish is a percentage equivalent. Scholarship forms ask for one anyway. A generic multiplier gives you a number. The examination office gives you a document.
The calculator does arithmetic. Your handbook holds the rules. Where the two disagree, SUSL is right.

GPA is credit weighted: multiply each grade point by the relevant course credits and divide by the applicable total credits. The source document is linked at the top of this page if you want to read the original wording.
You can compute something. Whether SUSL or anyone else will accept it is a different question, and the answer is usually no without an official equivalence.
