A rigorous academic experience for the next generation of problem-solvers.
GYSO challenges students to apply knowledge rather than simply recall it. Problems are grounded in evidence, logic, and real-world contexts across seven connected disciplines.
Participants are assessed on conceptual understanding, mathematical reasoning, computational thinking, English communication, interpretation of data, and clear scientific reasoning.
Learn about our academic mission →Seven fields. One curious mind.
Science is learned by doing.

- Evidence-based reasoning
- Interdisciplinary problem-solving
