Build confidence. Find your starting point. Keep learning. 1600 Standard brings math practice and SAT, ACT, AP, CLEP, and DSST preparation into one app. FIND YOUR STARTING POINT Begin the 32-question Math check with basic arithmetic, then explore more challenging questions as the check adapts to your answers. SAT and ACT starting-point checks help identify areas to focus on. UNDERSTAND THE ANSWER See feedback and worked explanations during your check. Try a similar question for extra practice, or flag a category you want to revisit—even when you answered correctly. PRACTICE WITH FLASHCARDS Focus on one full-screen card at a time. Build arithmetic confidence with addition, subtraction, multiplication, and division categories, or practice exam content in the SAT and ACT sections. FOLLOW YOUR PROGRESS Keep track of your learning, return to skills that need attention, and pause and resume your practice. Reset an individual course without clearing your progress in other courses. EXPLORE TOGETHER Parents can use “Pretend I got this answer correct” to explore how the check progresses. Pretend answers are identified separately and do not count as demonstrated mastery. MAKE PRACTICE WORK FOR YOU Use read-aloud features and adjustable reading and display settings. Work through problems on scratch paper, then review the steps in the app. Study features do not require an online account. Learning progress is stored on your device. Starting-point checks provide study guidance, not verified grade placements or guarantees of an exam score, admission, or academic credit. 1600 Standard is an independent educational product. It is not affiliated with or endorsed by College Board, ACT, or the organizations that administer the referenced exams.
