Well, what's your approach? It's hard to give helpful advice without knowing how you're working with problems. Here's what I do:

1. Read the question stem. What am I solving for? What information is provided (actual values, percents, variables, etc.)? Can I set up an equation or a method to solve? If so, it will make it easier to see what I need from the statements.

2. Scan the statements. Which one is easier or more straightforward? Start there and eliminate some answers before dealing with the trickier statement.

3. Work through the process of elimination:
Is the statement I started with sufficient?
Is the other statement sufficient?
If neither is sufficient on its own, are they sufficient together?

Thanks a lot for the inputs Bill.I approach DS questions in a similar fashion as you have told but yet I find it difficult to rephrase certain questions at times.

Kindly let me know where I am going wrong or has it got something to do with strengthening the basics?

"Target Test Prep is the closest to the official version of the GMAT exam, about 99% accuracy in terms of the quality and quantity of information. The course has excellently created singular sets of focused lessons and tests for every possible topic that one could come across in the official GMAT exam."

"The TTP course maximizes the efficiency of the time you spend studying. It will take time and effort but I could almost guarantee that if you complete the course exactly as it is laid out you will get an amazing score. They also have a very responsive team willing to help with any questions you might have."

"TTP has two things that I think no other test prep company offers: A teaching approach that reinforces understanding and an attitude that will give you the mental preparedness needed to succeed on the test. TTP gives you a deep understanding of the concept you need to know while teaching you how to think."
