Background: Two 8th graders spoke to FOX 5 NY's Jodi Goldberg about a state-required Earth and Space Science exam they took which they believed was unfair. One of them, Samuel Tae exclaimed: "My Heart Dropped, am I supposed to know this?" The other student, Andy Ryoo, told Goldberg, "The test felt like a reading comprehension test, one of the questions was about toll payments - weather wasn't covered, which is a huge topic, and we spent months on it."
"Yo my bro, this morning, I saw the new guy and my heart dropped, I was like, am I supposed to know this guy?"
