Does retaking a class replace the old grade?

It depends on your school's policy. Many colleges use grade replacement (only the new grade counts). Some only replace if the new grade is higher. However, application services like LSAC (law school) count ALL attempts, so both grades affect your LSAC GPA.

Is it worth retaking a class to raise GPA?

Usually yes, if your school replaces the grade. Retaking a D or F course and earning an A can significantly boost your GPA. Use our calculator to see the exact impact before deciding.

Understanding Repeat/Retake Policies

How repeats are handled depends on your school and the application service:

Grade Replacement (Most Common)

The old grade is excluded and only the new grade counts toward your GPA. This is the default at most US colleges. Some schools only replace if the new grade is higher.

Count All Attempts (LSAC)

Law schools via LSAC count every attempt â€” both the old and new grade factor in. Retaking still helps, but less dramatically than under replacement.

AMCAS (Medical School)

AMCAS also counts all attempts. Additionally, AMCAS treats A+ = A = 4.0 (no 4.33 for A+).
