To continue the discussion, CAT as an exam too has evolved over the last decade.
Earlier students had to attempt 150 questions in 120 minutes (40 Sec per question) In such a scenario, the focus was inevitably of the speed of calculations.
However, today's avatar of the CAT has 60 Questions and 2 hrs 20 min to answer them. (2+ min per question)
The focus has unequivocally shifted from speed to knowledge.
It is up to the aspirants to decide what they want from their preparation - short cuts or knowledge.
