GRE guidesMultiple Choice

Section

Quantitative Reasoning, after the Quantitative Comparisons

Select one

Five choices, oval buttons, exactly one correct

Select one or more

Square boxes, usually three to eight choices, any number correct

Credit

Select one or more needs every correct choice and no others

Instructions

The question may say "Indicate all such values" or give an exact number to select

## How it works

Select-one questions are standard problems with five choices, shown with round buttons. Select-one-or-more questions use square boxes; you tick every choice that works, and there is no partial credit. If the question states how many to pick, you must pick exactly that many; if it says "indicate all", anywhere from one to all of the choices can be right.

## Worked example

The integer n is greater than 10 and less than 40\. When n is divided by 4 the remainder is 3, and when n is divided by 3 the remainder is 1\. Which of the following could be the value of n? Indicate all such values.

1. A15
2. B19
3. C23
4. D27
5. E31
6. F35
Show the answer

19 and 31

Every choice leaves remainder 3 when divided by 4, so the second condition decides. Dividing by 3: 15 leaves 0, 19 leaves 1, 23 leaves 2, 27 leaves 0, 31 leaves 1 and 35 leaves 2\. So 19 and 31 work. Check with the pattern: numbers that meet both conditions are 7 more than a multiple of 12 (7, 19, 31, 43), and only 19 and 31 lie between 10 and 40.

## A method for Multiple Choice

1. 1  
### Read the choices before you calculate  
Their spread tells you how precise you need to be. Far-apart choices mean you can estimate; close choices or choices with variables suggest plugging in or working back.
2. 2  
### Check the format  
Round buttons mean one answer. Square boxes mean one or more, and the instructions tell you whether a specific number is required.
3. 3  
### Pick the fastest route  
Solve directly when the algebra is short. When the question has variables in the choices, substitute a simple number; when it asks which value works, test the choices, starting from the middle if they are in order.
4. 4  
### For select one or more, find the rule  
Work out the condition, range or pattern every correct answer must satisfy, such as a minimum and maximum value, then check each choice against it rather than solving from scratch each time.
5. 5  
### Check every box before moving on  
On select-one-or-more, go through all the choices even after finding one that works. A single missed or extra choice makes the whole question wrong.

## Traps to avoid

* Stopping at the first correct choice on a select-one-or-more question.
* A choice that is the answer to a middle step, such as the value of x when the question asks for 2x.
* Assuming at least two choices must be correct on an "indicate all" question.
* Answering a question about the least or greatest value without checking the ends of the range.

## Multiple Choice FAQs

Is there partial credit on GRE select-one-or-more questions?

No. You must select every correct choice and none of the wrong ones to earn the point.

How do I know if a GRE Quant question has more than one answer?

Select-one questions use round buttons and select-one-or-more questions use square check boxes, and the instructions say "indicate all" or state how many to choose.

Can every choice be correct on a select-all question?

Yes. Unless the question states a number, any number of choices from one to all of them can be correct.

Should I work backwards from the answer choices?

Often, yes. When a question asks which value satisfies a condition, testing the choices can be quicker than solving, especially if the algebra is long.
