How come my writing tutor said my paper was great, but my content area professor gave me a low grade?

Your tutor looks at your paper as a process of drafts not as a final product. Moreover, tutors look primarily at the structure, logic, and linguistic elements of your paper more than the content. It’s a good idea to get feedback from your content area professor before you submit the final draft.
