Questions are adapted from past entrance papers of Japanese graduate schools, drawn from over a hundred universities across difficulty tiers and organized by school tier and subject area; overall they run slightly harder than the originals. Beyond the core subjects, the bank also includes optional subjects that some schools set in this field's entrance exam (for example: mathematics, probability and statistics, optimisation, economic history, accounting, law, and Japanese essay writing). Choose the subject areas and difficulty tier that fit your own target.
