Prompt engineering technique where the model is instructed to make its reasoning explicit step by step before giving the final answer, improving performance on logical or mathematical reasoning tasks.
In AIF-C01 (Domain 3) and GENAI-L (Domain 3) it's compared with zero-shot and few-shot. Question: improve a model's accuracy on a complex math problem → explicitly ask it to "think step by step" (chain-of-thought).
Chain-of-thought prompting is a concept that can show up on the exam. Check the full guide to see it in context.
