A few minutes before he took the stage for a sold out show at the Music Farm on Wednesday, Atlanta rapper Waka Flocka stopped next door by for a cram session at Charleston School of Law.

Posted around 10:45 p.m. Wednesday night, the “Go Hard in da Paint” rapper posted a pic of himself studying up inside CSOL’s library, which shares its historic trolley barn buildings with the Farm.

On Thursday, CSOL said the rapper’s stop at the library was “a great energy boost” for students studying up ahead of exams.
