TOKYO -- Twenty-six students at Japan's prestigious Hitotsubashi University cheated in an exam by sharing answers through Internet-capable cell phones, a university spokesman said.

A professor teaching an introduction of E-commerce class, became suspicious after many students had exactly same answers in the exam, the university's vice president, Takehiko Sugiyama said.

Upon questioning, the students admitted that they sent each other E-mails through their cell phones during the exam.

The 26 students did not get credits for the class, DPA reported.
