Description
Unique credits=previous+resit-reusable; remaining=max(0,required-unique).
Education credit bookkeeping depends on conversion factors, overlap, prior recognition, caps and prerequisite assertions. Contact hours and recognized credits are different quantities; a numerical equivalence or waiver flag does not establish accreditation or authority to award a qualification.
Unique credits=previous+resit-reusable; remaining=max(0,required-unique).
When to use this tool
Use Course Resit Credit Reuse when checking the stated credit, overlap, rounding or prerequisite convention.
How to use the tool and how it works
- Enter previousCredits, resitCredits, reusable, requiredCredits. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read uniqueCredits, remaining. Use the output convention below.
Require nonnegative prior/resit/required credits and reusable overlap within both credit amounts. Unique credits=previous+resit-reusable; remaining=max(0,required-unique).1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| previousCredits | Previous Credits | Required. Finite number; minimum 0. |
| resitCredits | Resit Credits | Required. Finite number; minimum 0. |
| reusable | Reusable | Required. Finite number; minimum 0. |
| requiredCredits | Required Credits | Required. Finite number; minimum 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| uniqueCredits | Unique Credits | Required. Finite number. |
| remaining | Signed or clamped remainder under the exact convention specified above. | Required. Finite number. |

}Limitations and assumptions
- Overlap is a supplied duplicate-credit amount; course equivalence and institutional reuse permissions are not verified.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
Alternative or Complementary methods
Consult the institution’s current recognition and qualification rules and verified completion/evidence records for actual credit decisions.
