The daughter had received approval for extended time on the test and took the exam at a West Hollywood test center where a corrupt proctor, Mark Riddell, corrected her answers after she left the center, according to court documents.
Sartorio will be sentenced by U.S. District Judge Indira Talwani on Oct. 11.
Sartorio and a New York couple who also pleaded guilty Wednesday bring to 10 the number of East and West Coast parents convicted of the charge of conspiracy to commit mail fraud and honest services fraud.
