I totally revamped my college application resume a few months ago, and it made a huge difference! I focused on clear sections: education, extracurriculars, awards, and skills. Highlighting leadership roles in clubs and specifying my contributions helped clarify my impact.
Also, I included metrics where I could. Instead of just saying I volunteered, I mentioned how many hours I logged and the outcome of my efforts. This approach made my resume less cluttered and way more appealing.
