Five schools in western Norway have rescheduled their midterm exams to allow students to attend upcoming Justin Bieber concerts in the capital, the country's Ministry of Education and Research said Wednesday.

 The Canadian pop star is scheduled to perform in the Norwegian capital on April 16 and 17 _ stoking fears that some students in remote schools will skip midterm exams scheduled to take place at the same time. 
  
 Bieber is extremely popular in the Nordic country, where his free concert in Oslo last year resulted in dozens of injuries as teenage girls fought to get better glimpses of the 19-year-old icon. 
  
 To accommodate this Bieber-mania, five schools in the Alesund region _ located some 230 miles (375 kilometers) northwest of Oslo _ have rescheduled exams. 
  
 Kristin Halvorsen, Norway's education minister, said she did not intend to intervene with the schools' decisions. 
  
 "I am concerned that students should be concentrating when they take tests and midterms," Halvorsen wrote The Associated Press in an email. "The local schools have the responsibility to schedule the local midterms, and if they think there is any reason to change the dates, they have authority to do so." 
  
 As the minister explained, "We've all been 14-years-old and know that interests can be intense." ||||| European Pressphoto Agency Canadian R&B singer Justin Bieber performing on stage during his latest European tour School administrators on the west coast of Norway, preparing to deal with the return of Bieber fever to the small Nordic nation, have decided to pull ahead exams in order to avoid conflicts that may arise due to the megastar’s upcoming concert in Oslo. 
  
 Students at five schools in the town of Alesund will have their midterm exams moved to April 10 and April 11, a week earlier than scheduled. After all, Justin Bieber has a concert scheduled at the Telenor Arena in Oslo on the original testing dates of April 16 and April 17. 
  
 “We considered that this was a battle that we could not win this time,” Roar Aasen, the principal of the Blindheim secondary school in Alesund, told national broadcaster NRK. He expects Mr. Bieber’s upcoming show to lead to sparse classroom attendance. 
  
 Five hundred students will be affected. Alesund is about an eight hour drive from Oslo, or an hour by plane. 
  
 The 19-year-old Canadian performer made waves in Norway last May when he played a free concert on short notice. Oslo police confirmed the show would be taking place late in the evening in a Tweet, and throngs of fans flooded the streets. 
  
 Mr. Bieber’s 2012 concert outside the massive Oslo Opera House is believed to be one of the biggest musical performances in the nation’s recent history. Security was tight as fans crowded the waterfront less than one year after the tragic domestic terrorist attack by Anders Behring Breivik, which led to the deaths of 77 people – mostly teenagers. 
  
 This year, half of the girls at Mr. Aasen’s school are expected to attend one of Mr. Bieber’s Oslo shows, according to interviews done by NRK. The Norway stop is the beginning of a Nordic leg of his current tour, which will take him through Copenhagen, two stops in Sweden and Helsinki. 
  
 While Mr. Aasen is racking up fans among the young “Beliebers” at his school, his decision has drawn some criticism. “I would have said no to this,” Oslo schools commissioner Torger Odegaard told the news agency. It would not be appropriate in Oslo…I don’t think this helps to raise respect for the school.” 
  
 Liv Holm Heide, the newly appointed director of the student organization Elevorganisasjonen, was also disappointed. “It should take something serious to keep students from attending the midterm exams, perhaps something a little different than a concert.” |||||
Output:
Say what you will about Justin Bieber's recent troubles, but he's still quite popular—popular enough to cause one entire town in Norway to change its school exam schedule. Alesund is about eight hours away from Oslo, but the school district still expects low attendance at five of its schools when Bieber plays in Oslo later this month. Midterm exams were originally scheduled around the same time as the concerts, so administrators decided to reschedule them a week earlier in order to avoid any conflicts, the Wall Street Journal reports. "We considered that this was a battle that we could not win this time," one principal tells a local broadcaster; half of the girls at his school are expected to attend a Bieber concert. Bieber's Oslo show last year led to throngs of fans in the streets (and, the AP reports, dozens of injuries), and was one of the biggest recent musical performances in the country. But the Oslo schools commissioner disagrees with Alesund's decision. "I don’t think this helps to raise respect for the school," he says.
