For our children, we start with the PSAT in 10th grade (to kind of get used to taking a standardized test) and also we have them take the SAT in the spring of 10th grade, as a kind of freebie, no prep, no stress (other than having to find their way around the school, figure out how to fill in the answer circles, etc). We'll see how that works for my second child!
For my first child, it worked great, she scored a nice score on that 10th grade SAT, and then when it came time to take the SAT in 11th grade, there was not as much pressure as she had already received a pretty good score. With more math under her belt she easily scored a little bit higher. She also took the ACT and loved it, thought it was easier (for her) and scored a really nice score as well. She is taking it again today, trying to up her score by 1 point so that she can qualify for $2000 more a year in scholarship money.
My second will be taking his first SAT this spring, we'll see how this method works for him!
As far as prep goes, we didn't do any SAT or ACT prep with any of them (other than regular homeschooling of course!) and so far so good.
How about you? I'd love to hear what other homeschoolers do for these tests...do you do prep? When do you have your students take them? Other insights? Thanks for sharing!
