The app systematically rotates through all Algebra, Advanced Math, Problem Solving, and Geometry sub-skills. ■ MOBILE-FIRST LEARNING TOOLS • Distraction-Free Format: All questions are formatted as 4-option multiple choice to eliminate typing errors and provide a seamless mobile experience. • Built-In Desmos: Access the official Digital SAT Desmos graphing calculator directly on-screen (requires internet). • Scratchpad & Formulas: Draw directly on the screen with your finger or stylus, and easily access the official math formula sheet. • Tactical Timers: Practice with standard 60-second intervals to mimic the real test, or use 15s/30s lightning drills to build mental reflexes. ■ LEARN WITHOUT PENALTY • Two Attempts: You get two tries per question with no point penalties for mistakes. • Pedagogical Hints: Get a logic guide after your first wrong answer to help you find the solution without giving it away. • Error Analysis: Targeted repetition of your weakest areas produces the largest score improvements. ■ TRANSPARENT PRICING Start for free with an initial pool of questions to build your fundamental skills, followed by a free daily question allowance to keep your practice consistent.
