What does the ASE A6 study guide cover?

Every area of the A6 Task List — what each area tests, how many scored questions it's worth, and the specific tasks under it — so you study exactly what the exam blueprints, in the right proportions.

Is this the ASE study guide?

No. ASE publishes its own free study guides at ase.com; this is an independent guide that follows the same public Task List. Our questions are original and validated.
