Grind1600 provides an online SAT preparation platform designed to help students improve their standardized test scores through personalized study plans, adaptive practice questions, score tracking, timed drills, and other educational tools and resources.
While we strive to provide effective preparation materials, Grind1600 does not guarantee any specific test score, score improvement, or academic outcome. Our tools, practice materials, and study recommendations are intended for educational and informational purposes only and do not constitute professional tutoring, academic advising, or counseling.
You agree to use the Services only for lawful purposes and in accordance with these Terms. You shall not:
All content, features, and functionality of the Services — including but not limited to practice questions, answer explanations, study plan algorithms, score analytics, text, graphics, logos, icons, images, software, and design elements — are the exclusive property of Grind1600 or its licensors and are protected by copyright, trademark, and other intellectual property laws.
You are granted a limited, non-exclusive, non-transferable, revocable license to access and use the Services for personal, non-commercial educational purposes.

All practice questions, explanations, and study materials are proprietary. Unauthorized sharing or distribution of these materials is strictly prohibited, and we actively monitor for such violations.
You may submit content through the Services, including study notes, feedback, forum posts, and profile information (“User Content”).
