So last night I took my final exam in " Public Opinion and American Politics " . It 's the shortest class I ' ve ever taken . It was during the first summer term , a six week class meeting for three hours , two times a week ( Tuesday and Thursday ) . So in total we had twelve class meetings .
What may be the reason that they took the summer class ?
Pick the best answer from the following options:
A. They had previously failed the class .
B. They wanted to graduate in the summer .
C. They needed it to graduate in the fall semester .
D. They needed the class credits .
