If I copy and paste some of the information I have purchased can I get in trouble for plagerism through my school? If my professor runs my essay through the system will it pick up that I copied it?

Hi,

Yes, copying and pasting someone else's work and not giving proper attribution for that (in other words, claiming the work is yours) is considered plagarism. Turnitin.com, copyscape, and other programs that your professor uses will pick it up. Better to read something, summarize it, then create a works cited at the end of your paper. Then you are good to go.
