5. Is USABO hard?
USABO is a challenging exam that requires students to have a comprehensive knowledge of different aspects of biology. Participants need to have a thorough understanding of biological concepts, problem-solving skills, and the ability to apply knowledge in practical scenarios. Since each stage increases in difficulty, with the final round being the most difficult, USABO is known for its challenge. Students who want to prepare for the USABO will need to spend time learning biology in class and seek additional learning opportunities outside of class. The high level of competition and the depth of knowledge required make the USABO a challenging but rewarding experience for high-achieving students passionate about biology.
6. How to prepare for the USA Biology Olympiad?
Catherine Wang, the instructor and content generator for the USA Biology Olympiad, shared some of the studying strategies that worked for her. There are many good ways to study, and different methods work differently for each person, but these suggestions can serve as a good foundation for students to customize their studying strategies to discover what works best for them.
- Three-pass strategy: Similar to the three-pass strategy that Professor Keshav at the University of Waterloo introduced for reading research papers, Catherine customized the strategy for studying chapters. She recommended students read a chapter once. Then do another read-through, but this time highlights important information. Finally, read the chapter a final time, focusing on the highlighted portions, and jot down essential notes. This reinforces the learned material, and aids in retention.
- Read about the same topic from multiple resources: Utilize textbooks, online materials, and reputable sources in biology. Diverse perspectives can enhance your grasp of difficult topics by giving you multiple ways to approach and understand them.
- Memory Techniques: Enhance memorization by employing mnemonic devices and creating memorable stories associated with specific concepts. Mnemonics can aid in recalling complex information, making it easier to remember biological processes and terminology.
Frequent Self-Quizzing: Regular self-quizzing is crucial for reinforcing learned material. Create flashcards, quizzes, or mock exams to test your knowledge. This active recall technique helps in identifying areas that need further attention, and solidifies your understanding. - Ways to actively engage with material: This can involve using Visual Representations of concepts, like drawing out pathways and chemical structures to visually comprehend complex biological processes. You can also engage in discussions with classmates to exchange ideas and clarify doubts. You can also consider participating in a Teaching Simulation where you explain biological concepts to your peers as if you were teaching them to a patient or caregiver. These forms of practice reinforce your understanding by forcing you to articulate complex ideas in a simpler, more accessible manner.
- Reinforce material through related competitions: Participate in related competitions to reinforce your knowledge. Applying learned concepts in a competitive environment enhances your problem-solving skills and prepares you for the challenging aspects of the USABO.
Success in the USA Biology Olympiad requires a combination of effective study strategies tailored to your individual strengths and preferences. Experiment with these techniques and customize them to discover the approach that works best for you!

7. Why should students participate in the USABO?
For students with an interest in biology, participating in the USABO is an excellent choice, because it would shape your academic and professional journey.
Academic Challenge: The USABO is a challenging academic competition that guides students to dive deeper into the world of biology, and go beyond what you typically learn in the classroom. Richard Zhu, the USABO National Gold Medalist said “…I began to realize just how compelling biological understanding is — with a side of collaboration and innovation. I researched endonucleases, discussed biology with and helped aspiring biologists out online…”
Access to valuable networks and connections: The USABO creates a community of like-minded individuals who share the same interests in biology. After passing the online exams, finalists have the opportunity to learn with other finalists for 10 days. Finalists bond with one another through field trips and classes, fostering bonds that can last a lifetime and provide a supportive network for their academic and personal growth.
College Readiness: The content covered in the USABO competition will prepare students for college-level biology courses and labs. During their USABO journey, students will gain a deeper understanding of advanced biological concepts while also developing crucial skills such as thinking critically, solving complex problems, and applying scientific principles effectively.
Be sure to check official USABO websites and resources for the most up-to-date information and announcements regarding the competition. Good luck with your preparation, and we hope to see you succeed in the USABO and beyond!
