<p>Most of my scores from the October ACT were satisfactory, except for that one outlier. I want to go into a STEM field, so I don't know how much it will affect me, but I'm still apprehensive about sending the score. Also, if I send ACT scores, will schools that normally consider SAT II's still accept them?</p>
