Southern Miss requires SAT or ACT scores, so take your first test by spring of junior year and use the summer before senior year plus senior fall for retakes. Since the priority financial aid deadline is March 15, a December retake should still leave time for scores to arrive, but earlier retakes give you more room to improve your score.
