My kid took the ACT multiple times in order to improve her scholarship. She got a 33 (and thus the Presidential) on the last test date that was accepted. She had no problem graduating with honors with a triple major and never came remotely close to losing her scholarship. I don’t think ACT scores have all that much to do with getting good grades in college - a good work ethic, good time management skills and a willingness to seek out help when needed will go further, IMO.
