Box 1 can only include "tuition and related fees"
from publication 970:
"qualified education expenses are tuition and certain related expenses required for enrollment or attendance at an eligible educational institution.
Related expenses. Student activity fees are included in qualified education expenses only if the fees must be paid to the institution as a condition of enrollment or attendance. However, expenses for books, supplies, and equipment needed for a course of study are included in qualified education expenses whether or not the the materials are purchased from the educational institution.
so for example, if the book(s) or computer wasn't required for a class, it can't be included. My suggestion is for anything you add to Box 1, be able to support the requirement (e.g. syllabus would be a good supporting document) if the IRS were ever to come knocking.
