Sign up for your own account for a month or a year if you're a student. Or get your parents to pay for your account. They can create and cancel the account for you, but you'll be the one to use it and get better grades...but they don't even have to give you their credit card number! If you're an educator, you can purchase your own account to use the full educator functionality.
Try out EssayJack for a month, or string a few months together and use it for a semester or for years upon years in a row. It's entirely up to you. You can sign up online for your class or course or whole department.
Or maybe you're a group of parents homeschooling children, and you want to share resources and teach a number of students all at once. You can buy a bulk account, and get all the reviewing and sharing functionality with your children. It's easy, and you can cancel at any time.
