NBA baller J.R. Smith is a star on the court, on the links AND in the classroom ... 'cause the champ just got his grades back for his first semester of college -- and he got a 4.0!!!
Smith -- who skipped college to go straight to the NBA in 2004 -- decided to revisit the opportunity to get an education and enroll at North Carolina A&T this past summer.
So far, he's been crushing it as a student ... announcing his grades are better than what most people even dream of.
"I can't even describe the feeling," Smith said on Tuesday.
