We also provide customized problems for each concept.
The questions are presented in a basic problem format that can be solved by simply applying the concept, and basic skills can be strengthened through repeated training.

Build skills by type with representative problems applying concepts and variations of problems of varying difficulty.
We analyzed the types of questions that appear on the exam and systematically presented the concepts once again.

Additionally, representative problems for each concept were presented to provide training in applying the concepts.
We have provided concept-specific transformation problems of varying difficulty levels to enable selective learning.
