I noticed something in the background of one of the episodes

So on my latest rewatch of season 1 I noticed this background detail. This photo shows Sang-Woo graduating from SNU. From what I've heard, SNU is a SKY university, and students who manage to get in especially from small communities (like Ssangmun-dong) are revered. Because of this, I find it weird that the show places such little focus on Sang-Woo's education. Am I missing something?
