Raise your hand if you enjoy Data Sufficiency questions!

If you’re like a lot of people in the BTG community, your hand has not moved.  There’s no denying that Data Sufficiency questions are a significant hurdle for many; in fact, some students never fully understand what these questions are even asking of them.

With this in mind, I thought it might be useful to prepare a brief series on Data Sufficiency questions.  Today’s video is a basic introduction, with more in-depth DS lessons to come over the next few weeks.

I’d love to hear your feedback about this video and series, so please post a comment!

  • Hey Brent Video is good but it provides only very basic information for DS..I think it will be helpful to those first time visitors in forum and who have decided to take GMAT but dnt know much abt Question types...i think we shud link it up in our preparation strategy of 60 days to GMAT study guide...
    Anyways will be waiting for other Videos of tougher questions in DS with strategies to solve....

  • Hi Brent, A good intro to DS... My votes to ur DS series plan.
    If you could post on the types of DS questions, ways to tackle all available types, some DS examples on each of the math topics, common pitfalls and time-saving strategies, it will be extremely useful.

    Especially, in some DS cases, one may think too hard to solve them, but the answer wud be based on simple common-sense. So, I wud like u to stress on the simple approaches one could take to avoid the common traps. Thank U.


    • Hi thenali,

      Thanks for the input.
      I think the upcoming videos will address your suggestions.


  • Hey Brent,

    Nice initiative buddy. You are very true in saying that DS is a hurdle. My PS is too good, no doubts about that but my solutions get a little shaky when going for tougher DS questions, if you know what i mean. Easy ones and the medium difficulty ones are ok but the tougher problems are a real pain in the bottom. I am totally thumbs up and looking forward to this series. Go for it!!!


  • It's such a great resource that you are supplying and you're giving it away for free. I honestly enjoy seeing blogs that understand the importance of delivering a valuable resource for absolutely free. I honestly enjoyed reading through your post ;) Many thanks
