A Texas high school sophomore was arrested on March 31 and charged with a felony for hacking into the Spring Branch Independent School District computer system in order to change student's grades.

The unnamed 10th grader at Memorial High School, which is located in the western part of Houston, used a stolen password to make the grade adjustments for other students for an unknown fee, according to KHOU.com.

The district told KHOU that the investigation is continuing, but so far only one other student at the school is known to have paid for the grade switch.
