<p>The 16 ACT score is 23rd percentile, meaning 77% of the students who take the ACT do better than that. You would be shooting for 32 or above on the ACT.</p>
<p>But I would say that your mental health is more of a concern. It sounds like you have not had an evaluation or counseling, and that your solution to depression was homeschooling. </p>
<p>You should not be looking at starting over. You should assess where you are now - did you just start classes as a freshman? How are you doing in your classes? Do you live at home or on campus (usually community college students live at home)? </p>
<p>I would suggest that you contact the private school you graduated from, and talk to your GC from when you were in HS, and tell him or her of your plans.</p>
<p>At the very least, you need to find out the requirements to enter WashU. What is the average ACT score for their freshman class? What is the average GPA for their freshman class? </p>
<p>But I think an evaluation and counseling might be useful, perhaps at your current college. I also think you need to be realistic about getting into WashU. A 16 composite is way far away from what you would need. Target colleges that are closer to what’s achievable for you, and take an ACT course and take the ACT again.</p>
