GRE preparation requires concepts of basic mathematics. Revised GRE has two section of 20 questions each, divided into three sub-categories.They are multiple choice questions, Numeric Entry and Quantitative Comparisons. One has to revisit the old math formula for GRE Quantitative reasoning preparation.
These questions usually have five answer choices only one of which will be correct. A few questions may have 3-9 answer choices and more than one of them are correct.
It evaluates understanding of the basic fundamentals of arithmetic, algebra, to geometry and your ability to apply that knowledge effectively.
Since problem-solving questions will also have data interpretation questions with graphs and tables, learn to get comfortable with statistical/graphical data.
Practise calculations as much as possible to save time during the exam.
You have to learn judgment. What is it that the question is testing? For example, is the question looking for the area of a circle or just its diameter? Is it asking part of a ratio or the entire proportion?
Understand definitions like integers, numerical relationships etc.
Practise strategic guessing, back solving, picking numbers etc.
Utilize all study resources to polish your skills that will be put to test by the GRE problem solving questions.
Brush your arithmetic, geometry and algebra concepts.
Numeric entry questions have a problem that needs to be answered in the space provided. Numeric entry questions account for approximately 10% of the GRE quantitative reasoning section. Each test has ten questions and should take 12 minutes. The numeric entry questions require you to place the answer to the question into a single answer box or as a fraction into two separate boxes — one for the numerator and one for the denominator — using the computer mouse and keyboard.
This section tests your knowledge of basic mathematics and your ability to use it for solving problems.
You will need get your basics right. These questions will require you to remember all the formulae of basic mathematics that you learnt up to 10th grade like work-time relationships, decimals, unitary method, average, BODMAS, percentage, cost and profit, mean-median-mode and other concepts.
Quantitative Comparison questions cover approximately 35% of the GRE quantitative reasoning section. One should not take more than one minute for each problem. Each test has eight questions and should take 8 minutes. As the name implies, Quantitative Comparison questions (QCs) ask you to compare the sizes of two given quantities.
This section tests your ability to analyze data and make logical comparisons in order to solve problems.
Not all QCs will require some actual computation—they do rely on the same basic concepts as other GRE math questions, and sometimes, when the calculations aren’t difficult, crunching the numbers will be the way to go.The tough QCs require math reasoning.
QCs have an unusual format so get as many questions as possible for practising and getting comfortable with them.
Practise comparison more than calculation for this section. Avoid unnecessary calculations in the test of this section.
Brush up your concepts of basic arithmetic, algebra, geometry and a few miscellaneous topics (mainly data interpretation and applied math) to score well in GRE
