An Underrated Data Sufficiency StrategyI found Data Sufficiency absolutely dreadful when I started my GMAT journey. I would always be puzzled why the answer choice I select would be wrong almost all the time! My GMATClub
Error Log Statistics would show that nearly 90% of the Data Sufficiency Questions I attempted were wrong. I used to think my Concepts weren't clear. I spent a lot of time in the first two months trying to master theory and concepts. I thought this would solve my problems. What followed is pretty obvious! I was terrible at DS. In fact worse than earlier, mainly because I would try solving more Higher Difficulty Questions. I am a person who is devastated when my effort seemingly goes to waste. And naturally, I would think that this isn't my cup of tea!
But, All successful GMAT Takers have a common Quality.
Resilience! More importantly,
A kind of Resilience that requires a good understanding why effort was unproductive. I decided to assess why DS was a Weak Area for myself. I realized, over my Preparation, I wasn't using a concrete strategy to tackle Questions. No strategy to tackle a certain type of Question will indefinitely yield results that are not ideal.
I explored various resources both online and offline. I was looking out for something that would work in Data Sufficiency. And after a good amount of investigation, I found this.
https://www.gmatprepnow.com/module/gmat ... video/1102Let me tell you why I found this Video invaluable. When I tried to answer DS Questions,
Especially Yes/No Types(More on Yes/No Types Below), I would falter at a step as soon as I found a value ( for eg. x = 1 would satisfy the Question) and I would quickly jump to an Answer Choice and mark it. And as it turned out every time, I was marking the wrong answers.
Data Sufficiency requires you to be Smart with the kind of numbers you pick for Variables and to satisfy Conditions.
I found this Resource a God-Send. Why? Because it teaches you to
pick smartly for the kind of Values you take.
Try this out. I'll post a Question with an Example DS Problem on an updated version of this post later.
