Why it feels like the real thing

Most prep gives you a PDF and an answer key. synprep gives you the exam — the same interface, timing, and tools you'll face on test day.

The Bluebook interface

Section timers, question navigator, Mark for Review, and answer cross-out — the exact controls of the digital exam.

Official CED structure

Question counts, section split, and timing match the College Board Course & Exam Description for each subject.

Point-by-point self-grade

Free-response items reveal an AP-reader rubric: tick each point you earned and see an estimated AP score.

Every answer explained

A worked explanation for the right answer — and for the wrong ones, exactly why each distractor fails.

Three steps to a test-day rehearsal

01

Pick a subject & test

Choose from full-length practice tests across five AP subjects — each one a complete, discrete form.

02

Sit it timed

Work in the Bluebook-style interface against the official clock. Flag questions, cross out answers, use the calculator and formula sheet where allowed.

03

Self-grade & learn

Auto-scored multiple choice, point-by-point free-response rubrics, an estimated AP score, and a worked explanation for every question.
