Finals Grammar

I've been repeatedly told that I shouldn't worry about grammar and spelling while writing a final, but a sample answer from a previous year surprised me,

"First, we should still want to strike down stupid laws. The function of takings doctrine is to strike down stupid laws,"

While I fully agree with this statement, I didn't know I could resort to name calling in a final. Had I known this, I would have had a lot more fun in torts.
