Well to be honest cats were never easy to bell, but there are some cats that only 6 or 7 in 250 thousand people are able to bell them. 
This cat isn’t any animal, it is CAT or common admission test, the score of which is used to determine fate of thousands of students.
CAT is conducted by various IIM, one of world’s most prestigious management education institutes, on third Sunday of November every year. It is an objective test that usually consists of three sections, Quantitative aptitude, Data Interpretation and logical reasoning, and English. Quality, concentration and number of question that appear in the exam do not have any set pattern. CAT has changed its pattern literally every year in one respect or the other. While in 2006 it was 75 questions with easy quant and DI sections, 2007 saw 75 questions with tough quant and easier DI section. English has always been tough; actually it won’t be wrong to say that English is more of a lottery than a paper. You attempt more and hope to get at least half of them correct and you will be through.
Scores of CAT are declared with two respects, first is the normal scoring while the other parameter is percentile. A percentile is score that determines how many students that have appeared for the examination have scored lesser than you. It is a special feeling scoring 100percentile in the CAT among 250 thousand other aspirants. So if you feel like appearing for CAT keep in mind one thing CAT is unpredictable.
