Rising junior - what can I do to impress colleges more?

<p>So, I should stay in band then? I’m just worried that I won’t be taking enough AP classes that impress colleges.
In regards to testing, I’ll be taking the SATs this October. My practice test scores are consistently high 2200s - mid 2300s, but I’m striving for as close to a 2400 as possible.
I just have a few more questions about tests. Should I take the ACT? If so, when? Also, I plan to take SAT IIs for Math, English, and Spanish. Should I self-study for APUSH or World History? <:-P </p>
