Which statement about scratch work is true?

• A. It allows you to work out problems and calculations without needing additional paper.
• B. It must be done on scrap paper only.
• C. It is forbidden to use scratch work.
• D. It is optional for some questions.

Answer: (A)

Scratch work gives you a place to write out steps, formulas, and diagrams so you can reason through problems rather than relying only on mental math. When you jot down calculations and organize your approach, you’re less likely to skip a step or overlook a detail, which helps you reach the correct answer more reliably. On the PSAT, you’re allowed to use scratch paper or blank space provided during the test, so you can freely work through problems and check your results before finalizing your choice. This makes the idea that you can work out problems and calculations without needing to rely solely on memory or instantaneous mental math—because you have a dedicated space to write it all out—the best description of scratch work. It isn’t restricted to scrap paper only, it isn’t forbidden, and it isn’t optional for any questions; scratch work is a helpful, encouraged tool you should use as needed.
