Hi Ayushi! Data interpretation would require lots of patience along with speed. Most of the times the sums would be in format of caselets. Among the Caselet you would have 5 to 7 questions and out of them answers to 2 to 3 questions would be direct or minimal calculations. But rest one would need calculations. I would suggest you to try solving the one you can directly answer from the given data such that even if you do not have much time left later you might score from the answered once. Keep in mind to allot time for each and every caselet and if you are stuck somewhere do not waste time in the same. The key here is to practice more and more so that you would gain speed and confidence. Also see to it that if data interpretation questions do not carry more weightage than it would be advisable to make your other subjects strong such that even if you couldn't score in this section it would be compensated easily. All the Best Mate!
