Letter Grades and Percentage Equivalents

The University of Lethbridge employs a letter system of grading. It does not record grades as a percentage. On your transcript, these letter grades are converted to a numerical value on a four-point scale (a “Grade Point”) for assessing your overall academic performance (a “Grade Point Average” or “GPA”).

When I submit grades to the University, I use the following table of equivalences:

University description Excellent Good Satisfactory Poor Minimal pass Failing
Letter A+ A A- B+ B B- C+ C C- D+ D F
Percent range 100-94 93-90 89-86 85-82 81-78 77-74 73-70 69-66 65-62 61-58 57-50 49-0
Conventional value 100 92 88 84 80 76 72 68 64 60 56 49-0
Grade point 4.0 3.7 3.3 3.0 2.7 2.3 2.0 1.7 1.3 1.0 0

    Ithank you for this information. It is a good conversion scheme, but my performance would look worse than what it is if I was in the upper range of the grade. It would be better if gpa was reported as in-between numbers too eg. 3.4, 3.5, 3.6. Thank you.

    Hello, I was just wondering, what if your final percentage was 73.95? Is it rounded up or would it remain at 73? Thank you
