The PARCC test helps you prepare for the SAT in highschool. Since it doesn't count for your grade it's less stressful, and in a chart it shows that most people are anxious to do the PARCC test. The PARCC isn't for your grade it's for your school teachers to see so that they know where you are supposed to be placed in your next grade, like 6th grade to 7th grade.
I believe the PARCC test is better than the AIMS test at showing a students aptitude. It also does a better job at showing a student's strengths and weaknesses. It is also a more simple format and is overall better than the AIMS test. In general, we should have the PARCC test.
I personally think that the AIMS test would be a great test to take because it is a sample test that is for a particular grade level that helps the students understand the subjects before taking the actual test. I personally think that the PARCC test is two-thirds of what the states want to consider for a test.
In Montclair alone 40% of kids opted out. I wish I had had the fortune to say I could have opted out. It was mind-bogglingly hard and in fact was so hard, I had doubt the question were written in English and stumbled through the test only to wait another hour until the teachers fixed whatever bug we had now. Once, we had to wait 2 hours to debug but finally sent back to our classes having done no work.
