Click on your CDC below to download a database correction patch. The patch is only required if your serial number is listed in parentheses next to the CDC number.
(First ensure that the Master Your CDC program is not running. We suggest that you choose to run the patch from the current location. If a "security warning" from Microsoft is displayed, click "yes" you want to install and run the file.)

Please note that the database correction process will reset correct/incorrect, transfer, and custom exam flags.

If you'd rather make the database corrections manually using the "Edit" function in your Master Your CDC program, click on your CDC's link at the bottom of the page for a printable list of corrections by serial number.
