While GDZ is an excellent tool for and understanding difficult concepts, it is most effective when used after attempting the problems independently. Relying solely on copying solutions can lead to difficulties during unassisted exams.

: Includes detailed solutions for problems involving polyhedra, surfaces of revolution, and vector coordinates in space.

), allowing students to progress from basic competency to advanced problem-solving.

: Covers core topics such as trigonometric functions, derivatives, and the properties of powers and logarithms.

: It acts as a diagnostic tool to identify gaps in understanding before a classroom test.

: The logic used in these problems closely mimics the structure of the Unified State Exam (EGE) profile level.
