Idioms are expressions that have unique forms, and thus there are no specific rules to follow when determining the form of an idiom. They just take up form as per English convention.
If you are a native English speaker, most idiomatic expressions should already be wired into your brain because of all the exposure you’ve had to the English language. For non-native speakers, the task is more difficult.
The good news is that there are certain very common idioms that appear on the GMAT very often, and the ideal way around this for a non-native English speaker would be to memorize these. Here’s a quick review of the most common idioms:

Usually the best way to learn idioms is to practice questions. If while solving questions, you find a specific idiom structure that you were not familiar with, then just add the structure to your list of idioms to be memorized.
Your ear is the most valuable weapon as you try to figure out the proper form of an idiom. This is the one time when you are allowed to justify your choice by saying “it sounds better!” However, you must understand how to use your ear wisely.
For e.g., if you were asked to choose between:
(A) Writers are known attribute writer’s block as unwarranted distractions.
(B) Writers are known attribute writer’s block to unwarranted distractions.
The correct choice would be the second option, because “attribute to” is the correct idiom.
When you’re given a question to answer, first scan the original sentence for grammatical errors as usual, and then proceed to observing the usage of propositions in the given sentence. More often than not, the use of propositions at the beginning of the underlined portion is a big tell that the question is going to be about idioms, because most idioms are about the use of the correct preposition after a specific word.
Let’s have a look at an example:
The people known as Sumerians are credited as starting the first civilization and building the first settlements worthy of being called cities.
A) as starting the first civilization and
B) with starting the first civilization and also
C) for starting the first civilization and
D) as the ones who started the first civilization and
E) with starting the first civilization and
As you can see, the underlined portion begins with a preposition, and the word that comes right before this preposition is a verb. So now we are being tested on how well we know what preposition best fits after the verb “credited”. It shouldn’t take long to understand that the correct preposition to go here is “with”. This leaves options B and E open for consideration. Option B makes the sentence wordy; the “also” is clearly unnecessary. Option E is the answer.
The funny thing is, had there been a different word instead of “credited”, such as “celebrated” or “acknowledged”, then C would have been the correct answer.
Idioms with Built-In Parallel Structure
Certain idioms demand parallelism as a result of their structure. Here’s a list of a few of them:
X Acts As Y
Distinguish X From Y
X is the Same As Y
As X, So Y
Estimate X To Be Y
X is good, and So Too is Y
Between X And Y
X Instead Of Y
X, Such As Y (example)
Compared To X, Y
X is Known To Be Y
Think Of X As Y
Consider X Y
X is Less Than Y
X is Thought To Be Y
In Contrast To X,Y
Make X Y
View X As Y
Declare X Y
Mistake X For Y
Whether X Or Y
X Develops Into Y
Not Only X (,) But Also Y (the comma is optional)
X Differs From Y
Regard X As Y
