Typical summer before senior year angst! I need some help answering these questions.

My GPA is 3.00 currently. I haven’t taken any honor courses or any advanced courses like that. I’m taking the ACT in September, as well as October, and I’m now wondering if taking the SAT is a good option to consider as well. With my practice test (my last one being in June) I usually get a solid 27-29. I hope to get 30 or better, which I think is possible. I did most of my EC’s when I was homeschooled. (Freshman through Junior year.). I was on the debate team, newspaper club, book club. I helped run a social media account for a non profit bully prevention place. I volunteered with the Honor Guard quiet frequently. I’m in the process of getting a job, and I just started volunteering at a family shelter last week. I plan to focus on volunteering more this year, because I enjoy that a lot more than doing clubs.
