University of Michigan chances

<p>I'm applying to the University of Michigan LSA. I am a high school senior with a 3.8 gpa, a 27 ACT (I took it again recently, hopefully it went up to a 28-30), and a 1780 SAT. My extracurriculars are marching band, pep band, jazz band, all star band, and I am joining quiz bowl this year. My sophomore year I did a summer nuclear physics program. I have taken two AP courses (Literature and Language) I have taken history, biology, algebra, psychology, sociology, health, and french as dual enrollment courses. I will be taking a higher level psychology class and statistics later this year as dual enrollment. The reason I don't have more extracurriculars is because I have a job. I work 20-30 hours a week. I'm applying early action. The only other schools I am applying to are Central Michigan, and maybe Michigan State. So.... what are my chances? What can I do to make them better?</p>
