@LvMyKids2, the ACT offers a February test date (except for those in NY) so that’s what I meant by “early Spring.” I guess that’s technically still winter?
I suppose the ACT prep can help with the PSAT prep, but as noted, there are some significant differences between them, particularly as it relates to time issues. For my kids, having them take the SAT in the fall of junior year and then the ACT in February worked well.
