Two years of knowledge consolidation and aptitude test practice We analyze aptitude test questions from public junior high schools nationwide, organize important knowledge and basic content needed to solve the problems, and create a curriculum to be studied over two years. In addition to consolidating knowledge, we also incorporate plenty of aptitude test-style problem exercises. A structure that enriches math and language arts problems We have increased the number of math and language arts problems, considering the actual balance of questions on the aptitude test. By adjusting the balance of learning for each subject, we achieve effective aptitude test preparation. A curriculum that can be started from the 6th grade While focusing on two years of instruction from the 5th grade, the curriculum uses a spiral method so that students can start without difficulty even from the 6th grade. Students starting from the 6th grade can study properly without difficulty.
