Hi,  

• Each MAT report card contains six scores; one for every subject.
• Language Comprehension, Mathematical Skills, Data Analysis & Sufficiency and Intelligence & Critical Reasoning are reported on a scale of 0 to 100. In this section, scores less than 20 and more than 80 are rare.
• Indian & Global Environment score, is calculated separately on a scale of 0 to 100. In this section too, scores less than 20 and more than 80 are rare.
• The composite score of MAT is reported on a scale of 199 to 801. Less than 200 or more than 800 is a rarity and all scores below 200 are reported as 199 and all scores above 800 are reported 801. In means that even if you have scored less than 199, your composite score will be reported as 199. Similarly, 801 or more will be reported as 801.
• Composite score is calculated on the basis of performance in the first four sections as these sections are related to the skills required over a longer period of time in management field.
• These four sections are assigned equal weightage.    
• The most distinct feature of MAT is that the score scales of the first four sections and the composite scores are based on the performance of candidates who wrote the exam in 1996. This is so because their scores were defined in a way that a score of about 50 in a section and about 500 on a composite scale represent the average performance of that group.
• Further, for each of the six scores, a percentile below figure is given. This figure indicates the percentage of examinees who scored below the candidate based on the entire MAT testing population. The percentile below figure can change with each administration for the same scores.

Hope this helps you.

Good luck.
