i have an account, but i use it for college. They usually give you a course code and password to enter to submit it
I do not have any idea how you would go about entering something on turnitin.com without having access to code and pass
Plus if someone turns it on turnitin.com, (Your Assignment), and when you turnitin. its going to be 100% positive since someone has already turned it in before you (even if they just wanted to check)
Do you get what im saying?
btw check out this site:
