The 22-year-old never saw the need to take any GCSEs while a teenage prodigy at Everton - but he now hopes to pass his exams next year.
A source told the Daily Mail: "Wayne has had a lot of advice from his United manager Sir Alex Ferguson about how to fill his time away from football.
"Fergie said he should do something constructive.
"Wayne's girlfriend Coleen has also been encouraging him to get his head in the books.
"She did well at school and left with 10 GCSEs.
"If all goes to plan he will sit his GCSEs next summer in maths and English."
Rooney has also taken an interest in vintage wine.
