<h2>Plagiarism as a Problem of Modern Education</h2>
Plagiarism is a problem that can arise in many areas of modern life. However, it is especially relevant to the sphere of education and science. Over the years, students have been constantly cheating and working dishonestly. Nevertheless, with the development of the Internet and access to almost any literature, the problem of plagiarism in educational institutions began to occur again and again. Students are constantly looking for new ways to make sure that no one has noticed that they had used someone else’s work, but the professors also improve their methods of checking works.

<h2>Cheating in College</h2>
Previously, students did not have access to a huge amount of information and other students’ works. They shared the texts with each other, so plagiarism did not occur as often as today. Nowadays, there are many websites with free, or almost free, student papers on any topic and on any subject. Such online resources are a favorite place for dishonest students.

How do professors check for plagiarism? Sometimes teachers or their assistants can immediately identify plagiarism. If they rely only on their experience and knowledge, very often they do not notice that the student has cheated. This is not strange. After all, academicians have to read and review hundreds of students’ texts per semester, sometimes they forget what they have checked for a long time ago. Some students just change some sentences in the text taken from the Net and the professor may not notice the deception.
