Many students made mistakes in their Japanese writing. Specifically: 1) Some students wrote "スポッツ" instead of the correct "スポーツ" for sports. 2) When forming yes/no questions, some students incorrectly included "なん", which means "what" and makes the sentence sound strange. 3) Many students did not follow instructions when negating sentences, saying "No, my hobby is..." instead of the requested "No, it is not that." or "No it isn't X".
