Today my son took his PSAT test. Four or five moms were waiting for their children after the test and they told my husband that they were at the test that day because of me, his wife. But, he was quick to tell them that ACTUALLY it was because of you!
The day you sent out your emails about the PSAT I went into action and called our local school system. The registrations started THAT day! Homeschoolers couldn't register until the next week, but it gave me time to get the information I needed. I told a few friends, who must have told some friends. So, in case you ever wonder if you're making a difference, YOU ARE!
I was like the people you described in your PSAT information. The whole concept of PSAT and SAT totally overwhelmed me, partly because of what they mean: My son is almost done with high school! I'm so not ready for that to happen, so I try not to think about it. But, you forced me to get my head out of the sand and take the steps needed to make the test happen.
Anyone can take an AP test, even if they have not taken an AP course. The tests are really hard, really long, and the student needs to be prepared.
