July, 5 - DS day

Most of the day spent dealing with Data Sufficiency questions at testmagic. In the evening made couple of sections from DS1000 - few mistakes, all of them in the strangely formulated questions (like a story about a jeweler, who sells an item at some price; first option gives data that he made a discount and second option gives only selling price. Do I have to suppose always that there could be discount involved? It is never known either yes or no, maybe there even was involved something additional, I can invent many things to change the original price from real-life cases. Not sure that have to take a suppose of this data).
