pg. 44 starts a list of all courses and what categories they will fall into. the thing you have to check with each individua school is whether they require one year of "general biology" or just one year of "biology."
if its one year of biology, then any of the courses that fall under the aamcas category of "biology" will fulfill your one year requirement. For example, here are requirements for UCSD
You must complete the following lecture courses with a grade of "C" or better to be eligible to apply to the UCSD School of Medicine. Typically, each of these required courses must be completed at an accredited U.S. institution.
- One year (2 semesters or 3 quarters) of college-level Biology (excluding botany & biochemistry)
- One year (2 semesters or 3 quarters) of college-level General Chemistry (including biochemistry)
- One year (2 semesters or 3 quarters) of college-level Organic Chemistry
- One year (2 semesters or 3 quarters) of college-level Physics
- One year (2 semesters or 3 quarters) of college-level Math (only calculus, statistics, or computer science will be considered)
if its one year of general biology, courses such as anatomy and physiology might not count, although they will still be calculated in your BCPM. Here is UCLA's requirements, which specify general biology
ENGLISH One year of college English to include the study of English composition PHYSICS One year of college Physics (with lab) CHEMISTRY Two years of college chemistry to include the study of inorganic chemistry, quantitative analysis and organic chemistry (with lab)
BIOLOGY One year of general biology (with lab) MATHEMATICS One year of college mathematics to include the study of introductory calculus and statisticsSPANISHHighly recommended HUMANITIESHighly recommended COMPUTER SKILLS Highly recommended
