We learned a lot in college, but even those who attended the most elite institutions may have a gap or two in their educations. Namely, how to navigate all those pesky real-world issues, from starting a 401(k) to cooking dinner without the help of a microwave. Enter Society of Grownups, a new learning initiative from MassMutual and IDEO, launched Oct. 8, that aims to serve as a “masters program for adulthood.”

The target demo, according to “professional grownup” and director Nondini Naqui, might be “a 42-year-old who’s buying their first home, or a 27-year-old deciding if now is the time to expand their family, or a 32-year-old who’s moving in with their significant other and wondering how they should split the bills.” Basically, it’s all of us. Moreover, Naqui says, it’s about making growing up fun, rather than a chore. “When I was a kid, all I wanted to be was a grownup. Somewhere along the way, it lost that luster and that fascination, and I thought, ‘Oh, being a grownup has all these responsibilities.’ I just want to get back to that, to it being exciting. It’s not about sacrificing everything; it’s about living the life that you want to live.”

From their Brookline headquarters, the Society offers one-on-one financial advisement, cheekily named classes and supper clubs where fledgling grownups can mix and mingle. We rounded up just a few of the classes that caught our eye.

THE CLASS: No Cereal for Dinner (Learning to Cook Like a Grownup)

TAKE IT IF: You’ve subsisted on a diet of ramen, beer and pizza for the better part of the past five years. Cereal? Please, that would require having milk in the fridge, and last time you checked, the only stuff in there was half a case of Miller, a bottle of ketchup and something furry that might have once been a vegetable.

THE CLASS: Beyond the Hostel (Planning Grownup Trips)

TAKE IT IF: The highlights of your last big vacation included all-inclusive booze, a wet T-shirt contest and a questionable dalliance with a stranger.

THE CLASS: Loans & Groans (A Student Debt Workshop)

TAKE IT IF: You hear from the good folks at Sallie Mae more often than your parents. Payback’s a bitch, but you can do it!

THE CLASS: Home is Where… (The [Apartment, House, Loft, Studio, Bungalow] Is)

TAKE IT IF:You could have bought a small country (OK, a small country house) with the cash you’ve paid landlords—but aren’t sure whether you’re ready to be king or queen of your own castle.

THE CLASS: In case of a Zombie Apocalypse (Why You Should Think About a Will)

TAKE IT IF: You find legalese scarier than death itself. In case of an actual zombiepocalypse, it’ll be good to have your affairs in order. Actually, it’ll be good to have them in order either way.
