A PDF can't grade you.

Paper is great for drilling. What it can't do is tell you which reporting category is costing you points, or what to work on tomorrow. Your account does both, after every test.

On paperYou hand-grade 171 questions, then guess at a composite.
OnlineScored on submit, with a projected 1–36 and a range.
On paperYou know you missed 14 — not which reporting category caused it.

On paperPaper can’t tell you what to practice tomorrow.
