In this video I discuss how GMAT data sufficiency questions trap a test taker and what you can do to avoid the traps.

 
In this video I discuss one of the GMAT data sufficiency strategy that is helpful in dealing with questions that requires one to simplify algebraic expressions. I also demonstrate the common pitfalls in these types of GMAT data sufficiency questions, and give pointers on how to avoid some of the classic GMAT data sufficiency traps.

 
In this GMAT data sufficiency strategy lesson, I illustrate why you should not cross-multiply the terms in an algebraic inequality. In general, it is best to move all of the terms in an inequality to one side, simplify, and then tackle the additional information given in the statements.
