GRE Quantitative Reasoning in a Nutshell (2022)
2 sections: 35 min & 20 questions each
Types of questions:
1) - Quantitative Comparison
Choices are always:
A) Quantity A is greater
B) Quantity B is greater
C) The two quantities are equal
D) The relationship cannot be determined from the information given
- If the quantities only involve numbers eliminate choice D “The relationship cannot be determined from the information given”
- Plugging in method: Always pick 2 easy and opposite numbers such as 2 & -2 or 2 and ½ (+/- or whole # and fraction). (Be careful using 0 and 1 bc they have special properties)
- Always try to make the quantities look the same. Always do the same thing to both sides!
- Never assume, rely only on what you know, figures aren’t always drawn to scale
- Don’t forget other possibilities ( √4 = ± 2 )
- Don’t fall for look-alikes!
2) - Problem Solving
- Some questions will have one or multiple answers.
- RTQF x2: read the question first \(\times 2\), carefully! Before you look at answer choices figure out what are you trying to find and what kind of answer you expect (estimate).
- Pick a method
- Straightforward math (not the quickest, there is usually an easier trick)
- Pick numbers and plug in (difficult looking problems)
- Back Solve *notice the choices are in numerical order*
- Start with choice B or D
- If B is too large it is A, if B is too small check D
- If D is too large it is C.
- Strategic Guessing, process of elimination
- Check that your answer makes sense with your estimate and answers the correct question.
3) -
Data Interpretation- Some questions will have one or multiple answers
- Take your time to look at the title, scale, notes, and key on the figures
- Don’t be afraid to touch the computer screen, put your finger on the values you need
3) -
General strategies- Always take into account to use a strategic guess
- Skip often
- Always use scratch paper
- Questions are not intended to do lots of complex math, look for the shortcuts
- Don’t rely on a calculator in practice. You will only have access to a basic on-screen one
- Process of elimination!
- Always factor or unfactor
- Don’t get caught watching the time! Hide it if you find yourself stressing over the time
