How to Approach GMAT Data Sufficiency Questions
GMAT Data Sufficiency questions may seem hard at first, but this is only because they come in a format you have not seen before. The following several tips will help you approach Data Sufficiency questions correctly and will save you much time and effort.
- Read the question stem carefully, identify what information is provided in it, and what exactly the question asks.
- Determine what information you need in order to answer the question. Is it a value for one of the variables, an equation, or some other information?
- Evaluate each statement separately. While evaluating one of the statements do not consider information provided in the other statement.
- If each statement on its own is not sufficient to answer the question, then combine them. Read the question stem and both statements as one problem. Can it be solved? Do you have enough information?
- Make sure you know what is stated in each answer choice, and which choices can be eliminated once you prove sufficiency or insufficiency of each statement. This will come naturally as you solve more and more Data Sufficiency questions, but if your access to GMAT practice questions is limited, take some time to read and memorize answer choices.
- Do not waste your time trying to solve GMAT Data Sufficiency questions, as soon as you can see that certain information is sufficient or insufficient, you can answer the question or at least eliminate several answer choices.
