Just now, there is a program on TV. A gentleman is talking about IAS qualifying exam. He says that the aspirant must practise with old question papers such that when he/she sees an objective type question, the answer automatically comes to him/her...he says, once the aspirant starts thinking, he/she gets confused...the answer just comes to mind because of the amount of practice he/she has put in!!!!
This is what the coaching instt do ....he says it with pride, I say it with horror.
