Word like plagiarism

Solution 1:

There is no good alternative for plagiarism in an academic context, where the school or college usually has a code of conduct that requires a student to present his/her own work. Whether the provider is willing, paid, or simply a passive source, it’s still plagiarism. The professor can flunk the student in the course (I’ve done it myself); the school administration may impose other penalties, e.g. expulsion.
