Champions #24 mentions it's the start of a new school year.
Magnificent Ms. Marvel #1 also mentions the start of a new school year - and it's not the same one, as Champions has yet to use her new costume, so this must take place after Champions #7 (LGY#34).
That means at least two years have happened in-universe in the last five years in the real world. She's certainly a high school senior at this point. They're talking about college, and Miles has a birthday in his next issue - by the same writer. Miles had another birthday in an annual just last year, so I'm pretty sure Kamala's not more than a few months from her own 18th birthday. Wouldn't surprise me if Ahmed's runs on MMM and Miles Morales: Spider-Man both end with them graduating high school.
