One of the best method to crack GRE is use of Best gre prep books.
GRE Text Completion questions may require you to fill in one, two, or three blanks with the correct word--and there is no partial credit! However, multiple-blank questions aren't necessarily more difficult than one-blank questions.
These sentences contain more context hints to assist you predict the kind of phrases required. Furthermore, when you fill in one clean properly, that phrase is often a clue to the remaining word(s). Bear in mind that with multiple-blank Text Completions, you don't have to tackle the blanks in order; begin with the blank that is easiest.

Sentence Equivalence questions present you with one sterile and ask you to choose two words from a list of six to fill in that blank. The words will need to meet two criteria:
(1) They need to make sense in the sentence.
(2) They must give the sentence the same meaning. This means that process of elimination is a powerful tool. Even if two answer choices are synonyms, if they would not make sense in the sentence, eliminate those choices.
Also, if a word would make sense but no other choice would give the sentence exactly the meaning, eliminate that phrase from consideration. Once you eliminate words which don't make sense or who do not have a "spouse" word in the list, your odds of selecting the right two words from the remaining ones are much greater.
For example, if a business owner knows that two workers can create 9 wind chimes a day and needs to know how many wind chimes 6 workers would produce, install this proportion:
(3). Combine like provisions.

Divide to leave the desired variable by itself.
GRE Tip #6: Algebra -- Solving for x
Cross multiply: 2c = 9 × 6; twoc = 54; c = 27. This is frequently the only option once the problem gives you variables instead of numbers.
Note that the Quantitative Comparison tip above used picking numbers to illustrate just how positive and negative bases work with even exponents; picking numbers is an efficient means to refresh your memory of quantity properties principles in the middle of the evaluation.
Quantitative Comparison questions present you with just two quantities and inquire whether Quantity A is greater, Quantity B is greater, the two quantities are exactly the same, or the relationship can't be determined. These four answer choices are the same, so have them memorized by Test Day.
Anything done to the numerator of a fraction has to be done to the denominator, and vice versa. In this situation, the number of employees was multiplied by 3, turning 2 workers into 6, so the number of chimes must be multiplied by 3: 9 × 3 = 27 wind chimes. Whenever you have obvious numeric relationships to work with, this is often more efficient than multiplication.
Problem Solving questions likely look a good deal like mathematics questions you resolved in school. GRE Problem Solving questions might ask you to select one correct answer from five choices. Alternatively, they may be questions such that there may be one or more than one proper answers. They can also be numeric entry questions, providing you with a box in which to type the answer.
Do not waste time calculating the value of x. Instead, use your knowledge of number properties to deduce that x could be either positive or negative (because either a positive or negative number raised to an even exponent results in a positive number: 22 equals 4, and --22 also equals 4). Therefore, you can not tell whether x is greater or less than 0, and "The relationship cannot be determined from the information given" is the correct answer. Done!
Over and above on the GRE Quantitative section, you are going to be asked to isolate a variable. This may mean finding the value of a variable, such as x = 4 or y > --1, or it might signify solving for one variable in terms of the following, such as a = twobtwoc. Here is a useful set of steps for solving many linear equations or inequalities to get a variable:
A2 + b2 = ctwo, where a and b are just two legs of the triangle and c is the hypotenuse.
A proportion occupies the relative quantities of two or more quantities. On the GRE, proportions show up throughout the Quantitative section in issues involving arithmetic, algebra, and geometry. It is generally most helpful to write proportions as fractions. Use labels so you remember which value you put on top and which one you set on the bottom.
GRE Tip #7: Proportions -- Three Strategies to Solve
1. Eliminate any fractions by multiplying both sides by the least common denominator.
One of the GRE's favorite contours is that the triangle, and certain triangles have special rules that are well worth memorizing.
From the time you take the GRE, you've spent lots of your life reading to learn things so you can take tests and write documents. Success with GRE Reading Comp questions requires you to read differently. If the passage is all about the behavior of molecules in hypertonic solutions, remember that you are not taking a chemistry evaluation. If the passage is about the concept of chivalry in medieval romances, remember that you are not taking a literature or history test. You're taking the GRE, and also the GRE predictably asks exactly the same types of questions regardless of what the particular subject matter of the passage is.
Also, bear in mind that this question is not asking you to get the value of these quantities, just because of their relationship.
Currently there are three ways to solve for c. Which one is the most efficient for a given problem is based on the numbers involved
GRE Tip:Problem Solving -- Picking Numbers
Many questions will give you information in relatively abstract type. You might be given variables instead of numbers or proportions of an total, or you might be asked to apply number properties principles. A great way to bring any question like this down to earth is to pick quantities and then work with the amounts instead of unknowns.
Prepare to answer the following questions by taking notes concerning the passage's main idea, the arrangement of this passing, and some other opinions that arise and whose opinions they're. Taking these notes--making a Passage Map--will engage you in active reading, and also the notes will help you answer test questions. The GRE is "open book," so if you need to explore a detail, it will be right there on the monitor.
Put all terms with the variable you are solving for on one side by adding or subtracting on both sides.
The amounts you pick must be mathematically permissible. For instance, if the question says that a > b, you can pick a = 3 and b = two, but not the other way around. The point of picking numbers is to make your job easier, so choose numbers that will be easy to work with. Small positive integers, for example a= 3 and b = two, are usually good choices. Alternatively, if the question indicates that you will need to find a portion of a total, pick 100 for that total as doing so will make the percent calculations simple.
Quantitative Comparison -- Evaluate, Don't Calculate
Estimate: This, 9 is a little less than 5 times two, so c will be a little less than 5 times 6 or 30. Search for the answer choice that is a little less than 30. This is often the most efficient option once the numbers are large or awkward to work with and answer choices are.
