How AP Psych tests vocabulary
MCQs almost always present a short vignette and ask you to label the concept being demonstrated. Memorize the definition AND a one-sentence example.
FRQs frequently ask you to apply 5–7 named concepts to a single scenario. Practice writing one tight sentence per concept that names the term and ties it to the scenario.
Frequently asked questions
Quick answers — written by humans, not a chatbot.
How many psychology terms do I actually need to know?
Roughly 200 high-yield terms cover ~90% of the MCQs. Focus there, and learn the rest in context.
Are the new AP Psych redesign units very different?
The framework reorganized the same concepts under fewer unit headings. The vocabulary load is similar.
What is the fastest way to memorize this many definitions?
Spaced repetition (Anki, Quizlet) with a one-sentence example per card. Pure flashcards without examples do not transfer to the exam vignette format.
