Five schools in Norway have moved the dates of their exams to avoid running at the same time as Justin Bieber's European tour.

The Canadian star is due to perform in Oslo later this month (April 16 and 17) and it looked set to clash with the country's exam timetables.

It has been reported that five schools in the Alesund region of Norway have shifted their exam dates to make sure their pupils are fully focused on their education.

Norwegian education minister Kristin Halvorsen confirmed that the schools have the power to change their exam dates. He said:

"I am concerned that students should be concentrating when they take tests and mid-terms.

"The local schools have the responsibility to schedule the local mid-terms, and if they think there is any reason to change the dates, they have authority to do so... We've all been 14 years old, and know that interests can be intense."
