Nearly 20 private universities have signed contracts with the Nagoya-based Kawaijuku Educational Institution to supply them with questions for next year's entrance exams, the cram school has announced.
The move comes as an embarrassment to the Education Ministry, which in May asked the nation's public and private universities not to "out source" their entrance exams, citing potential problems over fairness and the risk of exam questions being leaked to candidates.
Kawaijuku also said Saturday that several other universities have asked the cram school to check for mistakes in their exams.
