Struggling cram school operator Yoyogi Seminar is planning to stop offering nationwide mock tests for university entrance exams next year as part of its restructuring efforts, a company official said Monday.

In January it will also stop assessing how applicants fared in unified college examinations.

For the annual entrance exams held ahead of the start of the academic year in April, major cram schools generally offer assessment services based on applicants' self-marking.

The performance assessment is also used to judge how the students will fare in each university's entrance examinations that follow the unified exams.

Yoyogi Seminar, founded in 1957, plans to close 20 of its 27 schools around the nation next spring to streamline operations. Because of the downsizing, it will become difficult to continue nationwide mock tests and to provide the performance assessment service, the official said.
