Hold your horses... Firstly, the minister tried to remove internet access from high school exams (good idea!), but parliament opposed this. Secondarily, the law is designed for cases where you know that someone cheated. A teacher might very well see someone exchange files on dropbox, but it is often impossible to prove. The law would allow the teacher to ask the student to show his/her "dropbox folder". The student can reject this, but naturally this will have consequences.
