Best of all? He knows how proud Mama Hockey is of this achievement.
"It's for her," Gaudreau said. "I remember when I started this. It was after my sophomore year. I started taking a few classes, and little did I know, but I was only two courses away.
"But then I turned pro and I kept pushing it off. But I made that promise to her, and to myself. This year was the perfect time to do it. I wouldn't have to worry about anymore - it was something we could all be proud of, and it would help set me up for the future, as well."
At 27, Gaudreau still has plenty of good years left on the ice.
But as everyone knows - as the years tick by - you can't help but plan for a life away from the rink, and into your 'twilight' years.
With a communications degree now firmly in his back pocket, a post-playing career in hockey broadcasting could be in the cards.
"Maybe!" Gaudreau said, enthusiastically. "That would be pretty cool. That might be something I try to get into one day."
For now, though, he's got a pretty good gig.
He enters the off-season feeling optimistic about his and the team's future. No. 13, himself, ended the year on a five-game point spree (1G, 9A), and was heavily involved in 14 (6G, 16A) of the final 16 games, overall, to overtake Elias Lindholm as the team's top striker.
That has him clamoring for October, already - especially with how Lindholm and Matthew Tkachuk fit so seamlessly with him in the absence of Sean Monahan down the stretch.
But first, a busy off-season awaits.
"I think for me most of the guys - and we've never really had this - but (Head Coach) Darryl (Sutter) gave us a set start date for training, and mine is June 14," Gaudreau said. "Normally I'd go home and take a couple weeks off, and figure out the best idea based on how the body is feeling.
"This year is a little different. I've got a few more weeks here, but I'll enjoy the time off and then get to it.
"We've also got our wedding coming up on Sept. 4, so there's a lot to look forward to right now. With all the restrictions up in Canada, we were hoping it wouldn't be like that in the States - and looking at it as we got deeper into the year, we thought it might be a bit better down here. We could get a bigger wedding, after all.
"My fiancée (Meredith) has a few wedding showers coming up and she's really excited about that. Before you know it, the big day will be here.
"Big summer.
"Big, big summer."
