Understanding the Format
Multiple Free-Response Questions: The FRQ section of the AP Biology exam consists of several multiple-choice questions that test your understanding of the core concepts covered in Unit 3. These questions typically include a stimulus, such as a graph, data set, or scenario, and require you to analyze, interpret, and apply your knowledge.
Types of Free-Response Questions
A. Grid-In Questions
Purpose: To test your understanding of specific factual information.
Format: Answer a direct question by filling in a numerical value or brief phrase in a grid.
B. Short Answer Questions
Purpose: To assess your ability to explain scientific concepts concisely.
Format: Answer a specific question in a few sentences, using scientific terminology and evidence to support your reasoning.
C. Long Answer Questions
Purpose: To evaluate your problem-solving skills and ability to integrate multiple concepts.
Format: Answer a complex question in an organized and detailed manner, providing evidence and explanations.
