For example, a student interested in computer science might focus on USACO for individual programming skill, participate in hackathons for applied project building, and enter ISEF with a computational research project. Each competition demonstrates a different facet of the same interest. Plan Your Competition Calendar SeasonCompetitions Fall (September-November)AMC 10/12, USACO first contest, Science Olympiad invitational Winter (December-February)USACO contests, AIME, regional science fairs, Science Olympiad regionals Spring (March-May)USAMO, Science Olympiad nationals, ISEF, state science fairs Summer (June-August)Hackathons, research for next year's competitions, MOP Track Your Progress Keep a record of every competition you enter, your scores and placements, and what you learned from each one. This data helps you identify areas for improvement and provides concrete evidence of growth over time for your college applications. STEM competitions complement other aspects of your profile. Students interested in computer science should prioritize USACO and hackathons, math majors should target AMC/AIME/USAMO, and engineering students should focus on robotics and science fairs. Freshmen should start with accessible competitions (AMC 10, introductory Science Olympiad events), while juniors should aim for national-level results. Read our guide on building a spike to understand how competitions fit into your broader application narrative. How to Prepare for STEM Competitions Start with the basics - Learn the format and rules for your target competition Practice with past exams - Nearly all competitions publish previous problems online Join a study group - Prepare with classmates or online communities (Art of Problem Solving forums) Take online courses - Platforms like Art of Problem Solving, Brilliant, and Khan Academy offer competition prep Compete early and often - Start with lower-level competitions and work your way up Learn from failure - Review every problem you got wrong; that's where the growth happens Explore all STEM competitions at our Competitions Hub, and take our Find My Fit quiz to find competitions matched to your strengths. Building a Competition Team Many STEM competitions are team-based, and building an effective team is itself a valuable leadership experience. Here is how to assemble and manage a competitive STEM team: Recruiting Members Look beyond the obvious candidates. The best teams combine students with different strengths: strong theorists, efficient coders, creative problem solvers, and organized project managers. Recruit from multiple classes and grade levels to build depth and ensure the team continues after seniors graduate. Host informational meetings, demo sessions, or practice competitions to attract interested students. Practice Structure Successful competition teams practice consistently, not just in the weeks before a competition. Establish a regular practice schedule that includes working through past competition problems, learning new concepts relevant to upcoming events, and conducting mock competitions under timed conditions. For teams preparing for events like Science Olympiad, assign each member specific events to specialize in while maintaining some cross-training for flexibility. Finding a Coach or Mentor A knowledgeable adult advisor can dramatically improve your team's performance. Approach science and math teachers at your school, local university professors, or professionals in STEM fields. Many companies encourage employees to volunteer as STEM mentors, so reaching out to local tech companies, engineering firms, or research institutions can yield excellent coaching resources. Funding and Resources Competition participation often requires funding for registration fees, travel, equipment, and materials. Develop a budget at the start of each season and explore multiple funding sources: school activity funds, parent booster organizations, local business sponsorships, crowdfunding campaigns, and grants from organizations like the National Science Foundation or state STEM education initiatives. Many competitions also offer fee waivers for students who demonstrate financial need. Using Competition Experience on College Applications When listing STEM competitions on your college application, go beyond simply naming the competition and your placement. Describe what you built, discovered, or solved. Explain the specific technical challenges you overcame and the skills you developed. If you led a team, describe your leadership approach and how you helped teammates improve. Admissions officers are more interested in what you learned and how you grew than in the specific ranking you achieved. A student who placed fifteenth but can articulate a fascinating research question they explored will often impress more than a student who won first place but describes their experience generically.
