A matrix block contains a series of bubbles arranged in four to five rows and columns. This type of OMR block is quite commonly used for column matching type questions, when one question has 4-5 sub questions. Questions that involve fill in the blanks, passages, etc. also make use of this answer pattern.
Questions are provided in four rows and each question has four options.
Sometimes, the matrix block can have five rows and five options for each question.
The rows are named as ABCD/ABCDE and the options are named as PQRS/PQRST.
Like all MCQ block questions, students have to fill the right OMR bubbles in matrix blocks too.
From each row, students have to choose one right answer.
For example, if the answer of A is R, B is P, C is T and D is Q, the final answer would be R-P-T-Q.
The scoring pattern of matrix block question would be different for different answer sheets. The examination committee decides on the marking or scoring pattern.
Each sub question has separate marks.
In most cases, the students receive marks for each right answer. Here, even if they provide wrong answers for one or two questions, they would get marks for the questions they have answered correctly.
In some exams, students are given marks only when all the sub questions are answered correctly. Here the students stand to lose marks if they have provided just one wrong answer and even if the rest are correct.
