May or not be helpful, but thought I would throw Ds story in–
I just saw this post and wanted to throw in that some schools change their policies from year to year. D started off testing last fall with a goal ACT score in mind for merit aid at one particular school. Their policy was that they superscored ACT math + E. So that is what she focused on and pretty much let science drift down and it showed.
I started to get a little uneasy when an AO mentioned merit qualifications may be changing and I encouraged her to also prep for the science section. She is really glad she did because the policy did change and they no longer superscore and they take best cumulative score!!
