My D wasn’t happy when I asked her to try the ACT again after she got a 34. I know that even without test prep (she didn’t do anything except take a practice test in a book), many students do better on a re-take just because of test familiarity. Fortunately her Saturday morning sacrifice worked in her favor. Her school offers a 4 year tuition scholarship for a 35, but only 1 year tuition for a 34. That one point increase was worth $$$$$$$ in her case.
