I can't believe that some people are suggesting that one should follow the route of rote learning...it might work for a few but trust me..it won't take u far...i have cleared the exam once...got allocated as well but didn't join coz i was pursuing a degree abroad...now i am planning to take the exam again...n hopefully will start studying in a month's time...but i didn't resort to rote learning last time and don't plan to start now...still to each his own..
