Based on the provided reference, the term "AB" is not a standard grading term. However, the reference does provide percentage ranges for letter grades. Assuming "AB" refers to a grade that falls between an "A" and a "B", we can infer its percentage based on the percentage ranges for "A" and "B". It is still not a valid grade and this estimation will be very broad without further information.
The provided document from Giant Campus Academy includes the following percentage to letter grade conversions:
- B: 84 – 86.9 Percent
- B-: 80 – 83.9 Percent
Without information on what 'A' grades equate to as a percentage, it is impossible to accurately provide a specific percentage for "AB". Therefore, the answer cannot be accurately determined based solely on the given information.
