Absolutely. The only caveat is that if a kid is on a slow track in math, he may struggle with the ACT, in particular, as it tends to have more Trig and Algebra 2 questions than the SAT or PSAT. (according to my kids' prep tutor ) So taking the test in Sophomore year may not be helpful except as practice.
