Test Grade Calculator

The formula is (correct / total) x 100. So 42 correct out of 50 returns 84 percent. With weighted point values, the calculator instead uses (correct x pointValue + bonus) / (total x pointValue) x 100, which produces the same result when every question is worth one point but adjusts correctly when each question is worth 2.5 points or you carry extra credit. The result is rounded to two decimal places.

The default US plus/minus scale used here: A+ is 97 percent and above, A is 93 to 96, A- is 90 to 92, B+ is 87 to 89, B is 83 to 86, B- is 80 to 82, C+ is 77 to 79, C is 73 to 76, C- is 70 to 72, D+ is 67 to 69, D is 63 to 66, D- is 60 to 62, and below 60 is an F. The simpler 10-point scale (no plus/minus) collapses these into A at 90 and above, B at 80 to 89, C at 70 to 79, D at 60 to 69, F below 60.

Strict mode applies cutoffs to the unrounded percentage, so 89.99% remains below 90%. Rounded-up mode first rounds to the nearest whole percent, so 89.5% becomes 90%. Use the mode stated in your syllabus; the calculator cannot infer an instructor's rounding policy.

Each US school sets its own letter-grade thresholds because there is no national standard. Most colleges use the plus/minus scale, but many K-12 districts stick with the 10-point scale because it produces fewer borderline arguments. Nursing programs, pharmacy schools, and military service academies often raise the passing threshold to 75 or 80 percent to align with licensure exam minimums. Honors and AP courses sometimes use a strict scale to discourage grade inflation. Always check the syllabus rather than assuming a scale.

Set the point value per question to match. A 40 question test where each question is worth 2.5 points totals 100 points: enter 40 as the total, 2.5 as the point value, and the calculator scales the percent correctly. For a mixed-weight test where some questions are worth 1 point and others 5, total the points yourself and use the weighted Grade Calculator (which accepts arbitrary score/out-of pairs) instead. Bonus points stack on top of the raw earned points before the percent is computed, so an 85 of 100 with 5 bonus points becomes 90 percent.
