The Fighter star endured a turbulent childhood, spiralling into drug addiction and spending time behind bars after dropping out of school in his teens.
But despite going on to forge a hugely successful Hollywood career, Wahlberg still has ambitions to boost his academic ability.
He tells Britain's The Sun, "I need to get a diploma before my kids graduate! I definitely want to further my education. I've got a few years.
"Somebody was on a plane with me recently and said, 'Oh, I'll get a guy to come over and tutor you for a couple of hours.' I was like, 'It will be more like a couple of months.' But I think I've got to do it. I'll feel great about it once I do."
