When students call me to discuss issues they’ve been having in their preparation, one of the most common concerns I hear is timing. Be it on practice tests or on the real thing, basically all GMAT test-takers experience a time crunch at some point during the test, if not throughout the entire exam. Now, if…
If you’ve been studying for the GMAT, you’ve inevitably found yourself in a situation where you were thinking “If only I had a calculator!” Many of my students express this sentiment, especially when doing weird digits questions or when forced to evaluate seemingly impossible percentages or fractions.

To properly determine whether a statement is sufficient, you must be focused on using only the information given. If, for example, a statement only tells you that -10 < x < 10, but says nothing else,…
