The term 'Barely Passing' can be represented by four crossword solutions: DEE (3 letters), SIXTY (5 letters), DPLUS (5 letters), and DMINUS (6 letters). DEE stands for the letter grade of D, which is the lowest passing grade in most educational systems. SIXTY is a reference to the numerical score of 60, which is the minimum passing grade in many schools. DPLUS and DMINUS are variations of the letter grade D, with DPLUS being slightly higher than a regular D and DMINUS being slightly lower. All of these solutions refer to the same concept of barely passing an academic course.
