Data Sufficiency

Hello,

I plan to take my GMAT in the couple of months and I have been focusing on the OG so far. I've been using the BTG 60 day study guide & while reviewing the answer choices, I see that my PS has a much better accuracy as compared to DS for the same topic. I am really not sure as to how to fix this. Should I re-do the concepts or is there any other approach?

Any help is highly appreciated!
Thanks
Radhika

DS is just a different animal. It takes a fair amount of practice to get good at it and it helps to learn some key things.

For instance, DS questions are often set up so that it seems that both statements are needed when in reality only one of them is. This is called a C trap, because it tricks people into choosing C. Once one becomes aware of this and sees it in action multiple times, one will be much less likely to fall for it again.

There are other things one can pick up, such as using an obviously insufficient statement to gain insight into what is going on in a problem. These tricks and techniques are discussed in many places online and in materials other than the OG.

Once you have done all the DS problems in the OG, then probably you would be well served by going to an online question bank and doing dozens more until you become totally comfortable with how they work and really get how to get them right.

It's good that you have a couple of months to process all this and get good at DS.
