The letter comes from the plus/minus scale you selected. A school on a different cutoff would report a different letter for exactly this percentage, which is why the scale is an input rather than an assumption.

Cutoffs vary between institutions and sometimes between departments. Where weights do not total 100%, the result is the grade on the work weighted so far rather than a projection of the final grade.

Practical notes about the inputs, assumptions, and result.

Because the letter is a property of your school, not of the arithmetic. An 88% is a B+ on a plus/minus scale and a B on a straight 90/80/70 scale. A calculator that hardcodes one of those is simply wrong for everyone on the other, so the scale is an input — and if your school uses no letters at all, you can ask for the percentage alone.

Yes. A score above the maximum is reported in full rather than rejected, which is exactly the case most people open a grade calculator to check. 105 out of 100 is 105%, and the extra points are called out separately.

Each category is scored on its own points and then contributes its weight to the total. Homework at 95% with a 40% weight contributes 38 points; exams at 80% with a 60% weight contribute 48; together that is an 86%.

The result is normalised to the weights you entered and the tool says so. That is the honest answer mid-semester, when the final exam has not happened yet: it is your grade on the work weighted so far, not a prediction of the final grade.

The result states it in percentage points, and in single-score mode also in raw points on the assignment itself. Needing 2 percentage points sounds small until you see it is 4 more marks out of 200.

Often, but that is their decision and not something a calculator can promise. An 89.6% is a B+ on the scale here; whether it becomes an A− is a conversation with your instructor rather than a matter of arithmetic.
