Synopsis for "Super Hero High"
Principal Amanda Waller reminds everyone that finals begin tomorrow. Most of students look forward to it, but Supergirl panics and takes off for the Kent Farm.
There she tells her adoptive uncle and aunt she's quitting the school. She can't deal with finals. Back on Krypton she failed her tests because of merciless bullying. She doesn't want to go through that ordeal again.
After she's finished her tale, the Kents encourage her and assure her she can handle anything, including finals. Feeling happier and more uplifted, Kara hugs them, says goodbye and flies back to Super Hero High School.
On the way back however, she's shot by a Kryptonite arrow and falls unconscious to the ground. Someone is gunning for Supergirl and her friends.
