At the end of the day, even after so much preparation there would be questions that looks unanswerable. What we are doing here is to equip ourselves with all the weapons in our armory to make sure we win the battle even if we lose some soldiers. Presence of mind and application on the exam day are also going to be vital as this is an objective exam and hence elimination is the best way to go. Customize yourself by taking a good understanding of your strengths and weaknesses. You could be a Civil Service aspirant or a Banking aspirant or solely a RBI aspirant. Adjust accordingly and launch your preparation. All the Best!
