<p>I don’t have an exact comparison for you, but my 12 year old took the EXPLORE last year and scored a 21. I was told at the time that that compared to a 20-25 on the ACT. She just took the ACT in Feb. and scored a 24, so it looks like the advice was pretty accurate. I would guess that if your child scored a 24 as a sophomore, with some prep, I would bet around 28-30 by end of junior year.</p>
