The Biology for Majors I textbook contains thirteen modules—roughly one module per week for a 16-week semester. If you need to modify the pace and cover the material more quickly, the following modules work well together:

• Module 2: Chemistry of Life and Module 3: Important Biological Macromolecules
• Module 4: Cellular Structure and Module 5: Cell Membranes
• Module 10: Gene Expression and Module 11: Trait Inheritance
• Module 12: Theory of Evolution and Module 13: Modern Biology

We recommend NOT doubling up Module 6: Metabolic Pathways, because it is long and especially challenging. Students will need more time for mastery and completion of assignments. In a longer semester, it can be taught over two weeks instead of one.
