AP Biology 12 is designed to be the equivalent of first year university level biology and is therefore more challenging than Biology 12. The content of AP Biology can be successfully completed only if students have completed Life Science 11 and Anatomy & Physiology 12 previously, or if they are taking Anatomy & Physiology 12 concurrently with AP Biology 12. Life Science 11 Enriched and Anatomy & Physiology 12 Enriched are strongly recommended to build a better foundation for AP Biology 12. An important component of the AP Biology course is extended laboratory work. There are mandatory laboratory experiments that must be completed by all students, as these labs are examinable on the AP Biology exam. Success in the AP Exam also provides students with post-secondary credit for the equivalent courses. To qualify for first year university chemistry credit, students must obtain school credit and a minimum score of 4 (four) on the Advanced Placement College Board Biology Examination written in early May. All institutions may not give this credit though local universities such as UBC and SFU do.
