Later that year, Jake begged his father to have Nog join them on their trip to the Gamma Quadrant for a science project, claiming that, "if Nog doesn't get a good grade on this project he's going to drop out of school." ()

When Nog asked Benjamin Sisko to be his sponsor for recommendation into Starfleet Academy, in 2371, Sisko's initial response was, "your reputation on this station leaves a lot to be desired. Your school grades are mediocre at best, and you've had run-ins with Constable Odo." ()
