MAT

Hello Debashree,
How many question you attempt is the secondary thing but with how much accuracy you attemt those questions is much important.
As we talking about MANAGEMENT APPTITUDE TEST {MAT}
If u manage to attempt 100 question from 160 . As in from
Quantitative aptitude 40 question
Language Comprehension 40 question
Data Analysis & Sufficiency 40 question
Critical Reasoning 40 question
As one more section of Indian & global environment was there which also comprises of 40 question was not be added in composite score . So give less importance to that section in comparison to others .But must attempt 10 to 15 questions of that section.
Tip: don't stick to single question for a long period of time.
you will manage to get a great score this way.
also,
Every year percentile depends on the marks of top scorer, level of difficulty changes so do as much as u can.
Good luck!
