Frequently Asked Questions
You need at least 68 correct out of 75, so you can miss 7. That is the 90% cutoff for an A on the standard scale.
Most schools set the passing line at 60%, which is 45 out of 75. Programs that require a C to count a course toward a major need 53 out of 75.
Divide the number you got right by 75 and multiply by 100. For example, 60 correct is 80.00%.
This chart assumes every question is worth one point. If your test has weighted sections, use the grade calculator instead and enter each section with its own points possible.
