I have never put my social security number on any standardized test from freshman thru junior year, including APs, SATII, and the SAT and ACT I took in the Spring on 08. I learned that colleges sometimes use social security number to match up scores to applications, so would it be a good idea to be my SSN on the tests now? I know for the AP exam I am not suppose to my SSN, since I did not in the previous years, but does that also apply to the SAT/ACT? Today, I called up ACT and asked them to put my SSN on the test I will take in the fall, was that a good idea, or should I ask them to remove it? And, what about for the SAT I will take in the fall: put my SSN or leave it off?
