About

⁹Are you preparing for the Biology Olympiad, or just want to dive deeper into biology? In this series, we’ll work through key topics covered in the USABO open exam, including cell biology, genetics, physiology, ecology, and more. Each session will focus on 1–2 chapters/concepts, with practice questions and discussion to strengthen understanding.

This series is great if you:
- Want structured preparation for the Biology Olympiad.
- Enjoy learning advanced biology topics beyond the classroom.
- Like reviewing with examples, problem-solving, and explanations.

We’ll go step by step through the material and build a strong foundation for competition success. No prior Olympiad experience required—just curiosity and dedication!

Note: This series will be lasting into January to cover as much material before the Open Exam.
