Suneo gets full marks from the class test, but isn't willing to show it to Gian or Nobita (who got 15 and 10 marks respectively) and decides to hide it, causing both of them to get suspicious. They conclude that Suneo might have gotten a zero and with Doraemon's help, destroy the paper before Suneo's mother finds out. Remade as Big Trouble! Suneo's Test Result in the 2005 series.
