Foundational Knowledge: Core Concepts and Definitions
What you must know
The Foundational Knowledge domain tests whether you can define and distinguish the building blocks of the field before applying them. Candidates should be fluent in the vocabulary of the discipline: the primary categories, the relationships between them, standard terminology, and the basic models that later domains build on. Expect questions that ask you to classify an example, match a term to its definition, or identify which concept a short scenario illustrates.
Traps to watch for
Questions here rarely test obscure trivia; they test precision. Common traps include near-synonyms that differ in one important respect, definitions that are correct in general but wrong for a specific subtype, and options that describe a related concept rather than the one asked about. Another frequent trap is a technically true statement that does not answer the question posed. Read the stem's final clause carefully: it tells you what kind of answer is required.
Rule of thumb
When two options both sound correct, ask which one matches the exact term in the stem. If the stem names a specific category, the correct answer usually reflects that category's defining feature, not a shared feature of the broader group.
Worked example
A question asks which feature distinguishes a subtype from its parent category. One option lists a trait shared by all members of the parent category; another lists the trait unique to the subtype. The shared trait is a distractor because it does not distinguish anything. Choose the unique trait.
Study approach
Build a one-page glossary of core terms with a short definition and one example each. Test yourself by covering the definitions and recalling them from the examples, then reversing the exercise.
