While teachers sooner or later began to recognize papers downloaded from online collections, papers copied from textbooks did not provoke any negative reaction, now the situation has changed. You cannot simply copy a text; that would be considered plagiarism. Each department determines the requirements for originality, and if the term paper does not meet them - it will not even be read.
