grutor
Someone who both grades and tutors for a particular class.
"That really cute guy is grutoring for our Data Structures class next semester! I'll be able to see him 2 hours a week just by going to his tutoring hours!"
"But then you'll have to do well on the assignments. The grutors all hate spending time correcting incorrect solutions."
