MBS Textbooks

Books for the 2019-20 school year

The MBS book store open date is Monday, July 22. There will be free shipping for all orders over $99 from Tuesday, August 6 through Monday, August 12.

Upper School Students

The Potomac School has contracted with MBS Direct to sell new and used textbooks for students in grades 9-12. Class schedules for Upper School students are now available in the Parent Portal section of CampusNET. 

Please note: Some course materials will be provided to students once school starts and student accounts will be billed in October. Students will also receive information in certain classes to purchase online materials directly at the start of the school year. This information can be found in the “Student Notes” on the MBS website.

Please log on to CampusNET and click on the "Parent Portal" link to view and print a copy of your student's classes. You will need this schedule to confirm which classes your child is enrolled in and which books will be needed for the school year.

To see the class lists:

  • log onto CampusNET and click on the Parent Portal link
  • Click on "Classes & Reports"
  • Click on "Course Enrollment"

Intermediate School Students

The Intermediate School office will purchase all text books for Intermediate School students and the student accounts will be billed.
