Q: What is on the GRE?

A: The GRE consists of two subtests - one involving math skills and the other involving verbal skills - and an analytical writing assessment.

Q: How is the GRE scored?

A: The math and verbal subtests each receive a score ranging from 130-170, in one-point increments. The analytical writing assessment is given a separate score, on a scale of 0 to 6.

The GRE – Frequently asked questions

Q: How is the GRE structured?

A: The analytical writing assessment comes first. It consists of two 30-minute sections, each requiring one to respond to a given prompt.

Next comes the GRE proper - 2 verbal sections and 2 math sections. The verbal sections each consist of 20 items, with 30 minutes to complete them. The math sections also consist of 20 items, but with 35 minutes to complete each of these sections.

The GRE is computer-based, but otherwise much like a paper-and-pencil exam – you may skip questions, leave questions blank etc. The best way to familiarise one with the interface of the computer-based GRE is to practice with PowerPrep software, which gives one the closest thing to the actual experience of taking the GRE.

The GRE – Frequently asked questions

Q: What are the math skills tested on the GRE?

A: Virtually all the math tested on the GRE is covered by most students by the end of the 9th grade. A few specialized topics, such as standard deviation, are more advanced, but their mastery is not necessary to obtain a high score. The GRE emphasizes problem solving, not math knowledge. GRE math items are hard not because the math skills themselves are difficult, but because the items that involve these skills require the test taker to analyze complex problems and implement multi-step solutions.

The GRE – Frequently asked questions

Q: How important is learning new vocabulary to improving one’s GRE score?A: Not very. Clearly, the more English words one knows, the better. But the revised GRE is designed to test vocabulary in context only, and so the emphasis is not on vocabulary per se, but on critical reading skills such as recognizing the roles of key words like “although” and “since”, and understanding the importance of surrounding words towards determining the meaning of a missing word.

Most test takers who plan to take the GRE within two or three months are better served by developing these critical reading skills than by trying to learn new vocabulary.

Reading comprehension:

• three answer choices, select all that apply

For the following question, consider each of the choices separately and select all that apply.

21.Which of the following statements is supported bythe passage?

A The pull theory is not universally accepted by

scientists.

B The pull theory depends on one of water’s physical properties.

C The pull theory originated earlier than did the push theory.

A tall tree can transport a hundred gallons of watera day from its roots deep underground to the treetop.Is this movement propelled by pulling the water fromabove or pushing it from below? The pull mechanismhas long been favored by most scientists. Firstproposed in the late 1800s, the theory relies on aproperty of water not commonly associated withfluids: its tensile strength. Instead of making a cleanbreak, water evaporating from treetops tugs on theremaining water molecules, with that tug extendingfrom molecule to molecule all the way down to theroots. The tree itself does not actually push or pull; allthe energy for lifting water comes from the sun’sevaporative power.

GRE Verbal: Item Formats

Reading comprehension:

• Select-in-passage: highlight the sentence from the passage that best meets the given description

10. In which sentence of the passage does the author

provide examples that reinforce an argument

against a critical response cited earlier in the

passage?

In Raisin in the Sun, Lorraine Hansberry does notreject integration or the economic and moral promiseof the American dream; rather, she remains loyal tothis dream while looking, realistically, at itsincomplete realization. Once we recognize this dualvision, we can accept the play’s ironic nuances asdeliberate social commentaries by Hansberry ratherthan as the “unintentional” irony that Bigsbyattributes to the work. Indeed, a curiously persistentrefusal to credit Hansberry with a capacity forintentional irony has led some critics to interpret theplay’s thematic conflicts as mere confusion,contradiction, or eclecticism. Isaacs, for example,cannot easily reconcile Hansberry’s intense concernfor her race with her ideal of human reconciliation.But the play’s complex view of Black self-esteem andhuman solidarity as compatible is no more“contradictory” than Du Bois’ famous,well-considered ideal of ethnic self-awarenesscoexisting with human unity, or Fanon’s emphasis onan ideal internationalism that also accommodatesnational identities and roles.

Quantitative comparison items nicely illustrate the importance of critical reasoning to the math section of the GRE.

Generally, the challenge is to recognize what makes comparing the values of the two expressions difficult, and then to remove this obstacle by implementing the relevant steps to simplify the problem.

The item itself will offer strong clues as to which steps should be taken to accomplish this goal.

The following are examples of common tactics for simplifying quantitative comparison problems.

Quantitative Comparison Items

The Basic Approach to Quantitative Comparison Items:

First step - check to see if one, the other, or both expressions are indeterminate.

• indeterminate – answer choice could be D. (Simplify as above, pick numbers)

• not indeterminate – answer choice could not be D. (Simplify as above)

Page 21: The Revised GRE Test Introduction and Overview. The GRE – Frequently asked questions* *For answers to other important questions about the GRE, or to register

Q: What do we mean by indeterminate?

A: An expression is indeterminate if it can have more than one value.

Examples:

“x,” “a prime factor of 15,” and “the base of a triangle with area 10 square meters” are all indeterminate expressions.

By contrast, “4,” “The average of 12 and 13,” and “the greatest prime factor of 15” are all determinate expressions.

Only if at least one of the two expressions is indeterminate, can the relation between the two expressions change, and thus can the correct answer be D.

Tips for picking numbers, Quantitative Comparison Items:

• Try simple numbers first; 0 and 1 often work best.

• Try the same number for more than one variable at a time, if possible.

• After plugging in one set of numbers, think about which new numbers will make the relation between expressions change.

• Don’t forget negative numbers, and numbers between 0 and 1 (especially if exponents are involved).

• Usually if the answer is not D, after plugging in a few sets of numbers you will understand why the relation does not change.

• If you’ve tried several numbers from all the important categories and the relation still hasn’t changed, it is probably safe to guess.
