b. The digits 1, 2, 3, 4 represent the students attempt on one question. All other digits are ignored. The 1 represents a correct choice. The digits 2, 3, and 4 represent an incorrect choice.
c. The digits 1, 2, 3, 4, 5, 6, 7, 8 represent the student’s attempt on one question. The digits 0 and 9 are ignored. The digits 1 and 2 represent a correct choice and the digits 3, 4, 5, 6, 7, 8 represent an incorrect choice.
