Quantitative Tips

Scan the data briefly to see what it is about, but do not attempt to analyze it in too much detail before reading the questions. Focus on those aspects that are necessary to answer the questions. Be sure to read all notes related to the data.
When possible, try to make visual comparisons of the data given in a graph and estimate products and quotients rather than perform involved computations.
Remember that these questions are to be answered only on the basis of the data given, everyday facts (such as the number of days in a year), and your knowledge in mathematics. Do not make use of specific information you recall that may seem to relate to the particular situation on which the questions are based unless that information can be derived from the data provided.

Do not waste time performing needless computations in order to eventually compare two specific numbers. Simplify or transform one or both of the given quantities only as much as is necessary to determine which quantity is greater or wether the two quantities are equal. Once you have determined that one quantity is greater than the other, do not waste time to find the exact sizes of the quantities. Answer and go on to the next section.
Consider all kinds of numbers before making a decision. As soon as you es ablish that the quantity in one column is greater in one case while the other quantity in the other column is greater in another case, choose answer (D) immediatelly and move on to the next question.
Geometric figures may not be drawn to scal. Comparisonjs should be made based on knowledge of mathematics rather than appearance. However, you can sometimes find a clue by sketching another figure in the margin of your test book or on the scratch paper provided. Try to visualize the parts of a figure that are fixed by the information given and the parts that are colapsible and changeable. If a figure can flow into other shapes and sizes while conforming to given information, the answer could be (D).

Read each question carefully to determine what information is given and what is being asked.
Before attempting to answer a question, scan the answer choices; otherwise you may waste time putting answers in a form that is not given (for example, putting an answerr in the form 1/4 when the options are given in the form 0.25, or finding the answer in a decimal form, such as 3.25, when the choices are given in fractional form, such as 3 1/4).
For questions that require approximations, scan the answer choices to get some idea of the required closeness of aproximation; otherwise you may waste time on long computations when a short mental proces would be sufficient (for example, finding 48 percent of a number when taking half of the number will give a close enough approximation).
