Test books are essential for evaluating student progress in an organized way. They are closely aligned with Textbook content.

Tests for Grades 1–5 have differentiated assessments. Each chapter has both a Test A and Test B, with Test A focusing on key concepts and fundamental problem-solving skills, and Test B focusing on the application of analytical skills and heuristics. Tests consist of multiple-choice questions that assess comprehension of key concepts, and free response questions for students to demonstrate their problem-solving skills.
