Some noticeable trends in CAT:
The following trends are clearly noticeable in CAT in the last few years.
a. The weightage of Math based questions has increased. Until 1998, we would have 85 out of 185 questions that were Math based. This is about 45%. In 2002, 2003 and 2004 almost 81-90 out of 150 questions. This is between 55-60%!!
b. The Problem solving section would constitute 1 out of 4 sections in the test until 1998. In the last 6 years, it has been 1 out of 3 sections. The importance of this section has therefore tremendously increased (from 24% of the total paper to 33.33% of the total paper)
c. CAT has been getting progressively tougher and thereby low scoring by the year. You no longer need fantastic scores of 100+ to clear the CAT. Over the years, SharpMinds students who have cleared the CAT and made it to the IIMs have had in the range of 75-90 attempts in the paper.
