<p>Hello I am a sophomore and I am highly interested in participating in the USABO and the USNCO. I have already started studying for the olympiads and I am planning to intensively study when school starts which is August 22 for me. I am reading the Campbell 8th edition Biology and the Molecular Biology of the Cell 5th edition. Is it enough time to get through most of it and is the Molecular Biology of the Cell worth reading? What are the best books for the USNCO? I need some advice. Thanks</p>
