Good preparation begins with good teaching.
Prepare for the SAT, ACT, and AP exams with carefully written practice questions, clear explanations, and lessons that develop the knowledge each exam assesses. Begin with free practice or study a subject in greater depth with a full course.
A sample from SAT Math
For what value of k does the equation 5(x − 2) + 12 = kx + 6 have no solution?
The explanation is part of the lesson: students should be able to see how the result follows from the equation.

A course for the subject you are studying
Students need different kinds of help at different stages of preparation. Some need to revisit a concept. Others need more practice applying what they know. The courses bring the study guide, lessons, questions, and assessments together so students can move between reading and practice as needed.
Read the study guide
Work through the study guide for your subject online, chapter by chapter. Return to a topic when a question reveals a gap in your knowledge.
Work through the lessons
Lessons introduce the relevant concepts and demonstrate methods through worked examples. Study a complete topic or focus on a particular skill.
Practice and review
Use original questions to apply what you have learned. Read the explanations carefully, including the reasoning behind incorrect choices.
Prepare for timed assessments
Use the practice tests available in your course to work on pacing and sustained concentration. AP materials also address free-response writing and scoring expectations.
Follow your progress
Review your performance by topic and decide what to study next. A missed question can point to a specific concept worth revisiting.
Course access
Full courses are available for $3.99 per month, per subject. Choose only the subjects you are studying. Free practice remains available without a subscription.
