Students with advanced preparation from high school may be eligible to place out of one or more of the modules in the introductory biology sequence (BIOL 101–104). Such advanced placement is available only to students who have both (1) received a score of 5 on the AP Biology exam, a score of 7 on the IB biology higher-level exam, a score of A on the GCE biology A-level exam, or the equivalent on other national standardized exams, and (2) demonstrated adequate proficiency on the Yale biological sciences placement examinations.

Each module in the introductory biology sequence has its own placement exam. Students may take all four or any subset of their choice. The exams consist mostly of essay questions and are scored manually by Yale postdoctoral and graduate-student instructors in the sciences. Students who take the exams will receive notification of their placement by e-mail prior to the beginning of fall term.

All students interested in the biosciences are encouraged to take the complete introductory biology sequence, whether or not they are eligible to place out of one or more modules. Even the most advanced high school biology course is unlikely to have covered the field at the level of BIOL 101–104. The professors teaching the sequence are leading scientific researchers, and the classes include discussion of recent cutting-edge research as well as instruction in how to read original research publications. For more information about BIOL 101–104, see under "Biological Sciences and Biomedical Engineering" in the Programs of Study section in May.

Note: Admission to BIOL 101 and 102 is capped for freshmen, who may not add the courses to their OCS worksheet prior to the second day of classes. Freshmen are permitted to register for BIOL 101 and 102 beginning on Thursday, August 28. During the registration process, students must select a discussion section for each course separately.

Prior to August 28, freshmen interested in taking BIOL 101 and 102 may access course materials by joining the Classes*v2 sites for both courses as shoppers. Important announcements and other documents will be posted on the Classes*v2 sites; the "Resources" folder on the BIOL 101 site is particularly useful.

Interested freshmen are welcome to attend the first lecture for BIOL 101. See the course listing on OCI for the time and location.

Please contact the BIOL 101–104 course coordinator, Surjit Chandhoke, with any questions about the introductory biology sequence or the biological sciences placement examinations.
