It's easy to ask a tutor a question: log in to NetTutor, select a subject, and click Ask NetTutor.
In addition to using live tutoring, you can drop off a question in the NetTutor Question and Answer Center or use the NetTutor Paper Center to submit a paper for review.
NetTutor provides tutoring for many subjects. A complete list of supported subjects can be viewed via the Subjects link at the top of this page.
You can review all of your previous tutoring sessions in the archives. These archives can be viewed, printed, and played back.
Time is only deducted when a tutor is actively working with you or providing feedback on your question and answer center question or paper.
