Hello Aspirant,

There are total 160 questions in MAT and these 160 questions are divided into 4 sections.So the composite score is the combined score of all the sectional marks. The composite score is your actual merit score considered for MBA admission in various colleges. The composite scores can range from 200 to 800. On the other hand you percentile score shows what percentage of people have scored below.So in your case, with a percentile of 33.43 means , you have scored higher than 33.34 percentage of students who wrote the exam.
