i feel like taco bell induced

i studied so hard for this international relations quiz and was pumped to ace it but when the timed little vomited questions in my direction, I was completely dumbfounded----it's like I didn't even read the chapter. (when i must have read it pLENTY of times until i was confident i was going to do aight). After i press submit, I'm thinking im gonna get a 7/10

but i got

a ing

4/10

i honestly felt like crying and i still do. help. it's the second week, and last week i managed to get a 7/10 but im drowning and losing faith in myself. it's my major, and it's imperative I get at least a B in this class. but my future looks bleak. 

s.o.s.
