Massachusetts Child Abuse System
Came up with during MCAS

5.
Stands for: Massachusetts Comprehensive Assessment System
A standardized test that must be passed to graduate high school in Massachusetts. While the high school curriculum is tailored to the material on the exam, most questions can be answered with a basic understanding of the English language and a minimal amount of common sense. Many people (parents) protest its existence because they think their kid won't pass, but all students know that it's a great waste of a week of school. While you do get almost four hours to do it in, most people finish in the first twenty and spend the remaining time reading, sleeping, or drawing dirty pictures on their desk with a whole box of #2 pencils.
The MCAS weeds out people that aren't fit to be a part of society.
