get a good score on the ACT

So, my first time taking the test, and I made a 25. I am proud of myself. I thought I would make much worse.

I took the practice test in the booklet given when the packet is received. I made an over-all 27. I am scared because of that. I made that score in my living room on the couch while drinking water in between tests. In October, I will be thirsty, hungry, and tired. I am freaking out.
