ACT Writing

Got my Writing Score back and pretty pissed. I thought I merked that test cuh on that writing part at the end wrote about my feelings, thoughts, opinions on curfews. Ended up with a score of 8 and a comment saying “Your essay maintained focus on the specific issue in the prompt.” I practically killed that test cuh I deserve better

Are they this strict? Help a brother out and gimmie me some tips so I can be guaranteed a perfect score on this writing portion
