This requires to use variables to hold the scores and the grade. If you are not allowed to use global variables you must declare them in your main() function and pass them to the functions:
int main()
{
    int grade;
    int score1, score2, score2;

    ReadScores(&score1, &score2, &score3);
    grade = GetGrade(score1, score2, score3);
    PrintGrade(grade);
    return 0;
}

The program's main is to contain only call statements.
I would read that in the sense of that it should not contain any operations but that variable declarations, assignment, and the mandatory return statement are allowed.

[EDIT]
After thinking about it a while I found a solution that does not use any variables in main():
int main()
{
    PrintGrade(GetGrade(ReadScores()));
    return 0;
}

Then ReadScores() must return a structure containing the data (which may be optionally dynamically allocated) that is passed to GetGrade() (which can free allocated memory) which returns the grade that is passed to the Print() function.
