I am new to this forum. I have been studyin for the GMAT for a few weeks now. I was going through OG12
and got around 10 out of 230 wrong in the PS but i got 40 wrong out of 174 in the DS. Is there a good approach to solve DS questions?
I feel like I'm kinda jumping the gun on some of these questions.
MGMAT doesnt have a whole book or section dedicated to it. Just wondering where I stand and if anyone has any advice on what I could do to improve my score, I would greatly appreciate any help.
Also where do you guys think I stand at this stage?
Are you making the mistake of quickly running through the problems? So you understand why did you did a problem wrong before moving on to the next?
I see this as a very common problem with people using OG. Are you spending enough time EVEN on problems that you attempt correctly? Maybe there lies the trick. It is not always true that the reason you marked an answer right is the right reason. In addition, reading each and every description in the OG helps you discover something new that you didn't know.
These are some of the general tips. Specific to DS:
1. Read each statement in isolation. When eliminating one and moving to second, read the problem statement again along with the second statement and ignoring the first. Sometimes you tend to mix up information you already know from the first and that causes the error.
2. "No" is also an answer. If it is asked "is x > 0?" and by using both statements individually or combining the two, you find out that you cannot find the exact value of x, but you get an idea that x is < -2 for sure. Then you have actually got the answer. Question was "is x > 0?", answer is "No". This is the next most common error.
Hope this helps.
