Common Mistakes to Avoid

❌ Using unweighted averages instead of credit-weighted GPA.

✅ A 4-credit A has more impact than a 3-credit A. Always use credit-weighted calculation.

❌ Not knowing the grade point values at your school.

✅ Most US colleges use the standard 4.0 scale, but some use different scales or +/- variations. Check your school's grading policy.
