How do I calculate my weighted average grade?

Multiply each assignment grade by its weight (as a decimal), then sum the results. Example: 85% on a midterm worth 30% contributes 0.30 x 85 = 25.5 points toward your final grade.

What grade do I need on the final to pass?

Use the final grade needed calculator: enter your current grade, the final exam weight, and your target grade. The calculator solves for the minimum final exam score required.

How do letter grades convert to GPA points?

Standard conversion: A/A+ = 4.0, A- = 3.7, B+ = 3.3, B = 3.0, B- = 2.7, C+ = 2.3, C = 2.0, C- = 1.7, D = 1.0, F = 0.0. Some schools use a +/- system; others do not.

What is the difference between weighted and unweighted GPA?

An unweighted GPA treats all courses equally on a 4.0 scale. A weighted GPA gives extra points for honors, AP, or IB courses — typically up to 5.0 — to reflect course difficulty.

Frequently Asked Questions

What is a weighted grade?

A weighted grade factors in how much each assignment is worth. For example, if exams count for 40% and homework for 20%, a 90% on exams has more impact than a 90% on homework.

How do I calculate what I need on my final?

Required Final Score = (Target Grade minus Current Grade times (1 minus Final Weight)) divided by Final Weight. Our Final Exam Needed tab does this automatically.

What counts as a passing grade?

Most US institutions consider 60% (D) a passing grade for credit, though many majors require a C (70-73%) or higher in required courses.

How is letter grade determined from percentage?

Standard US scale: A (90-100%), B (80-89%), C (70-79%), D (60-69%), F (below 60%). Some institutions use +/- grading within those ranges.
