Going to college in the fall

in May, I take my first exam in my life, so I'm very worried (((I chose history and social studies, but I don't know who to study for! I just want to exist without doing anything, but in order to fulfill my dream, I need to work and earn well. I wrote a 2-point math test, and it seems to me that the same thing will happen in May. I haven't had such apathy in a long time.
