Do you regularly attend tutoring?
Reconsider your traditional definition of "tutoring." You can use the extra time with your teachers to just ask additional questions about your classes, gather work, make-up work, make test-corrections, learn something new from a peer, and even just show your teacher that your committed to success in their class! Make a personal weekly tutoring schedule for your classes and record it in your agenda (before, during lunch, or after school all counts). Do this until your grades are where they need to be. Then, go ahead and reevaluate your tutoring schedule. You may decide you want to continue your tutoring schedule as you find it helps you to stay on top of your school work and maintain good grades.
