Reference Brief
The college-level passing scale, how category weights turn coursework into one final grade, and two worked examples — one with weekly quizzes, one without.
§Purpose & Scope
This page defines iNovaSchool's college-level passing scale and shows, with real numbers, how a course's grade categories combine into one final percentage and letter grade. It builds directly on the aggregation concepts in the Grading Setup SOP — this is where those weights and averages become an actual grade.
§The Passing Scale
iNovaSchool courses use the standard nine-tier passing scale, A+ through C-. Anything below a C- is a fail at the college level — this is the policy most schools in this catalog follow.
| Letter | Percentage | GPA Points | Status |
|---|---|---|---|
| A+ | 97–100% | 4.0 | Pass |
| A | 93–96% | 4.0 | Pass |
| A- | 90–92% | 3.7 | Pass |
| B+ | 87–89% | 3.3 | Pass |
| B | 83–86% | 3.0 | Pass |
| B- | 80–82% | 2.7 | Pass |
| C+ | 77–79% | 2.3 | Pass |
| C | 73–76% | 2.0 | Pass |
| C- | 70–72% | 1.7 | Pass |
| F | Below 70% | 0.0 | Fail |
Some institutions record a D-range grade on the transcript for anything between roughly 60–69%. At the college level here, that distinction doesn't matter operationally: C- (70%) is the floor — a course grade below that is not passing and the course must be retaken.
§How Weighting Works
A course grade is never one score — it's built from a handful of graded categories (Assignments, Discussions, Quizzes, Final Exams), each assigned a percentage of the total grade. To get the final grade, take each category's average and multiply it by that category's weight, then add the results together.
As long as the weights add up to 100%, the categories combine directly into a percentage you can read straight off the passing scale above. See the grade flow diagram below for how that actually plays out, item by item.
§Grade Flow Diagram
This is the mechanism from the previous section, drawn out end to end: each category's items aggregate into one average, each average is multiplied by its weight, the four weighted contributions sum together, and that percentage lands on a letter grade. The dashed path shows where the Quizzes weight goes in a course that doesn't have them (Example B).
1Example A — Standard Weighting (With Weekly Quizzes)
The most common breakdown in this catalog: quizzes are short weekly checks on that week's reading, worth relatively little on their own, while Assignments carries the most weight.
| Category | Weight | Sample average | Contribution |
|---|---|---|---|
| Assignments | 50% | 88% | 44.0 |
| Final papers / exams | 30% | 90% | 27.0 |
| Discussions | 10% | 95% | 9.5 |
| Quizzes (weekly reading checks) | 10% | 85% | 8.5 |
| Final grade | 100% | — | 89.0% — B+ |
2Example B — No Quizzes (Folded Into Assignments)
If a course skips weekly quizzes entirely, that 10% doesn't disappear — it's added to the category it's closest to. Since quizzes here are reading checks, Assignments absorbs the weight and becomes 60% of the grade instead of 50%.
| Category | Weight | Sample average | Contribution |
|---|---|---|---|
| Assignments (absorbs the 10% quiz weight) | 60% | 88% | 52.8 |
| Final papers / exams | 30% | 90% | 27.0 |
| Discussions | 10% | 95% | 9.5 |
| Final grade | 100% | — | 89.3% — B+ |
Decide what "Assignments" means before removing quizzes. If reading checks go away entirely rather than becoming graded assignments, the Assignments average itself may shift — confirm with the instructor what's actually being graded under the larger weight, not just the number.
§The Formula
Every example on this page uses the same formula — just with different weights.
Applied to Example A: (0.50×88) + (0.30×90) + (0.10×95) + (0.10×85) = 89.0%
Applied to Example B: (0.60×88) + (0.30×90) + (0.10×95) = 89.3%
Use the calculator to plug in a course's real weights and averages — including toggling quizzes off to see Example B's redistribution happen live.
Final Grade % = Σ (Weight × Average). Edit any field.
