The following table details the percent ranges assigned to the possible letter grades.

Based on the above chart the following are true when deciding when to select a percent value versus a letter grade:

• A mark of 80% or higher should be selected over A
• A mark between 65% - 79% inclusive should be selected over B, but not A
• A mark between 50% - 64% inclusive should be selected over C, but not B
• A mark between 40% - 49% inclusive should be selected over D, but not C
• A mark between 0% - 39% inclusive should be selected over F, but not D

P is considered a passing mark, therefore:

• A passing percentage mark or letter grade should be selected over P, and
• P should be selected over a failing percentage mark or letter grade.
