Guys, need help. I am an MBA (Marketing) 2014 pass out. Got placed but left around 6 months back. Made up my mind that would attempt CAT again and would appear for other exams like IBPS, CGL too.

But as I have stared my preparation, I am realizing am no more quite good at those topics as I used be - like Time & Speed, Time & Work, Number System, Progression etc.

Remember, during my CAT 2011 days, when I was in TIME, Jayanagar, Bangalore used to have such fun times here in PG. Really lost touch. Miss those Maths-days.

Why is it happening like this, guys??? 😞
