• A mark of at least 70 earns B
• A mark of at least 60 earns C
• A mark of at least 50 earns D
• A mark below 50 means F (Failure)

Note: Numeric marks are recorded accurate to one decimal point (0.1) and should be rounded up to the nearest whole number by the grading program.

The objective of testing is to ensure that students are assigned the correct letter grade, given their numeric mark.
