Some of the most common mistakes students make on the SAT include mismanaging time, misreading questions, careless calculation errors, and skipping practice on weaker areas. Others include overthinking easy questions or neglecting to review mistakes from practice tests. These pitfalls can be avoided by practicing under timed conditions, carefully reading each question, double-checking answers when possible, and focusing on consistent review of challenging topics. By identifying and addressing these common errors early, students can improve accuracy, build confidence, and boost overall test performance, making their preparation more efficient and effective.
