Prep for the Digital SAT in short sessions that actually fit your week. Flash turns test prep into a path you can follow. Work through lessons one step at a time, drill real question types, and see exactly where your reasoning went wrong instead of just seeing a red X. STRUCTURED LEARNING PATH Work through hand crafted, interactive lessons that span every topic on the SAT. Streaks, XP, and levels keep short sessions from turning into skipped weeks. TALK TO A TUTOR, OUT LOUD When a question stops you, press the mic and ask. The voice tutor answers in real time, works through the problem with you, and draws each step onto a worksheet as it talks. Diagrams, graphs, and the actual algebra appear as it explains them. Ask it to slow down, skip ahead, or start over. It is a conversation, not a video you scrub through. Every session is saved, so you can go back to anything you worked through. HUNDREDS OF PRACTICE PROBLEMS, FREE Solve hundreds of math and reading practice problems, with detailed and narrated explanations completely free. Learn how to use Desmos to solve math questions in half the time! FLASH PRO Pro removes the energy limit on lessons and unlocks unlimited conversations with the voice tutor.
