What to do senior year of high school?

I'm about to start my senior year and I want to make sure I'm doing everything I can to boost my college admissions chances. What are some essential activities or accomplishments to focus on during senior year? Thanks for your suggestions!

Tackling senior year with a strategic approach is key. Here’s what you should prioritize: First, keep up your GPA—senior year grades do matter. Second, if you haven't done so already, finalize your college list to include a range of reach, match, and safety schools. Work diligently on your college essays; they're a crucial component of your application and should reflect introspection, growth, and your uniqueness. Prepare for and complete any remaining standardized tests if they’re required or if they can strengthen your application. Remember to ask for recommendation letters early in the year; giving your recommenders ample time is courteous and can lead to more thoughtful letters. Moreover, continue with extracurricular activities, especially those where you hold leadership positions or can make a significant impact. Lastly, don't forget about scholarship and financial aid applications, which often have deadlines in the earlier part of the school year. By staying organized and proactive, you can navigate your senior year effectively.
