If Versus "Whether"
The distinction between the words “if” and “whether” is one that the GMAT often employs in highly complex sentence correction questions. The meaning of the two words is very similar, making it quite difficult to determine which one is the correct usage in any situation. Here, we will cover the difference between "if" and "whether" and how to determine their proper usage on the GMAT.
The fundamental difference between these two words and the simplest way to tell them apart is that “if” leads to a then clause and “whether” does not. Let us explain further, through the following examples.
Example 1 - If you promise to come along, (then) I will also come for the party.
As you can see, in example 1, the word “then” is written in brackets. The reason behind this inclusion is that the word is that, in this sentence, “then” is silent; it is not actually written in the sentence, its use is merely implied. Nevertheless, the clause "I will also come for the party" is still a then-clause and the sentence is perfectly correct.
Now let us look at a different example:
Example 2 - I am not sure if it will rain today.
Example 2 is not a correct sentence. Here, “if” is not followed by a then clause, meaning that “if” is not the right word to use. In such a case, "whether" would be the correct word to use. The correct form of this sentence is:
I am not sure whether it will rain today.
A very useful tip to keep in mind, when solving “if or whether” questions, is that in sentences where "if" is the correct usage, "whether" sounds very awkward. Although trying to determine the correctness of a sentence, based on whether it sounds awkward, is not typically a good strategy for GMAT sentence correction, this situation is an exception. To fully understand this point, please consider the following example:
Example 3 - Whether you promise to come along, I will also come for the party.
Example 3 is very awkward, in a very obvious way. You do not have to worry about encountering such a sentence on the GMAT, as it will never be written. . What is tested on the GMAT is cases such as Example 2, wherein, "if" is written but "whether" is the correct usage. Therefore, we can conclude that if you are caught between "if" and "whether" on the GMAT, most of the time, whether will win.
Like Versus "as"
Here, we shall cover the difference between “like” and “as” and exactly where these two words should be used. Although both these words are used to make comparisons, , there is a subtle difference between then that means that they are not interchangeable. Please pay close attention to this explanation; the difference between “like” and “as” is a fairly commonly tested concept on the GMAT. However this concept can often be difficult to grasp, as these words are used interchangeably, quite often, in everyday speech.
There is one main difference between the words “like” and “as”, the context in which it is appropriate to use them. "Like" is used when nouns are compared and "as" is used when processes or clauses are compared. Please go through the following examples to understand this concept, fully.
Example 1 - Jack's height, as that of his father, is exactly 190 centimeters.
A careful reading of example 1 will reveal that the heights of Jack and his father are being compared, meaning that the sentence is comparing two nouns. Therefore, this sentence is incorrect; the word “as” is not supposed to be use to compare nouns. In this sentence, the word "like" should be used to compare Jack's height to that of his father; the correct form of the sentence is as follows:
Jack's height, like that of his father, is exactly 190 centimeters.
Now, we will take a look at an example that covers the incorrect use of the word “like”.
Example 2 - Playing squash, just like playing soccer, is a great way for staying fit.
Example 2 compares “playing squash” to “playing soccer”; both of these are actions, meaning we can say that this sentence it compares two processes. Therefore, like is "like" is not the correct usage in this sentence, the word "as" is. Hence, the correct form of this sentence would be:
Playing squash, just as playing soccer, is a great way for staying fit.
Finally, let us take a look at an example with a different structure to gain some further clarity.
Example 3 - Playing squash, just like soccer, is a great way for staying fit.
As you can see, example 3 compares the action of playing squash to the noun soccer. This means that this sentence is actually something of a trap, as this comparison is fundamentally incorrect. In this case, whether you use "like" or "as" does not matter; the only way this sentence can be correct is if it is changed to compare playing squash with playing soccer, or squash to soccer.
Use of "Considered" and "Regarded As"
During your GMAT preparations, you might find that idioms pose a significant and unique challenge. Idioms must always be used in a certain way, and to answer idiom related sentence correction questions, you must memorize the rules governing their usage. These rules, typically, do not have much logical reasoning behind them, and are simply arbitrary grammatical guidelines. Here, we will cover the usage of two idioms, "considered" and "regarded as". Both of these terms broadly convey the same meaning, that something is true according to a particular opinion. However there is a stark difference in their usage that you must understand to identify incorrect GMAT answer choices, involving them.
Use of "Considered" on the GMAT
Use of Regarded on the GMAT
Because Versus "In That"
As we have mentioned elsewhere, idioms tend to pose an especially difficult challenge to GMAT candidates, as there is not much underlying logic to their proscribed uses. To properly identify incorrect uses of idioms, on the GMAT, you will have to memorize the rules governing their usage. Here, we will cover the correct usage of two idioms, "because" and "in that".
Difference between the use of "Because" and "In That"
A Helpful Tip
Use of "So as to"
Here, we will cover the correct usage of the idiom “so as to” on the GMAT. Please go through this articles carefully and memorize the rules governing the use of this phrase. Doing so will enable you to tackle your GMAT sentence correction questions, namely those that involve idioms, more efficiently and accurately.

Use of "Modeled"
Here, we will cover the use of the word “modelled” on the GMAT. Please go through this articles carefully and memorize the rules governing the use of this phrase. Doing so will enable you to tackle your GMAT sentence correction questions, namely those that involve idioms, more efficiently and accurately.
All things considered, it is not difficult to understand, remember, and apply the idiomatically correct usage of the word “modelled”. There is only one correct usage of this word, on the GMAT, "modeled after". If you come across any other usage, for example "modeled as per", "modeled like", or "modeled as", consider it to be incorrect. Please take a look at the following example to understand this concept, better.
Example 1 - Venetian, the famous hotel in Macau is modeled after Venice.
As example 1 makes clear, he correct use of the word "modeled" is to state that something has been modeled after something else.
Use of "Native"

Use of "Being"
In GMAT sentence correction, there are certain words and phrases that you must keep a close lookout for; their presence signifies that the answer choice is very likely to be incorrect. Keeping this fact in mind will help you solve the GMAT sentence correction section, much faster, by swiftly eliminating obviously incorrect answer choices. That having been said, you must also remember that the mere presence of these words is not a guarantee that the answer choice is wrong. There are exceptions to this rule that you must be mindful of. Here, we shall cover the use of one such word, "being", on the GMAT.
Why “Being” is Usually Incorrect
The Exceptions
1. Noun Phrase
2. When it reflects the passive continuous verb tense
Compared With Versus "Compared to"
Here, we will cover the use of the phrases "compared with" and "compared to" on the GMAT.Please go through this articles carefully and memorize the rules governing the use of this phrase. Doing so will enable you to tackle your GMAT sentence correction questions, namely those that involve idioms, more efficiently and accurately.
The Difference Between "Compared With" and "Compared To"
"Agree With" Versus "Agree to"
On the GMAT, there are certain idioms that you must pay especially close attention to. The use of these idioms is highly context-specific, and a slight shift context can necessitate the use of an entirely different word or phrase. Here, we will cover the use of the phrases “agree with” and “agree to”.
Use of Agree With and Agree To on GMAT
Use of "Distinguish"
Here, we will cover the use of the word "distinguish". Please go through this articles carefully and memorize the rules governing the use of this phrase. Doing so will enable you to tackle your GMAT sentence correction questions, namely those that involve idioms, more efficiently and accurately.
Correct Use of “Distinguish”
Where Versus When
Here, we will cover the correct use of the words “where” and “when” on the GMAT. “Where” and “when” are two of the words that that you must pay especially close attention to, while working on GMAT sentence correction, as their correct idiomatic use of such words can shift subtly but significantly, depending on the exact context. Such idioms are often used to set up highly complex questions that will require you to approach them carefully and have a firm understanding of how exactly the words are to be used.
The distinction between these two words is fairly straightforward. The word “where” is used to refer to a person or thing’s location in space, while the word “when” is used to refer to a person or thing’s location in time. To put it another way, “where” refers to “place” and “when” refers to time. Please go through the following example, carefully, to understand this concept better.
Example 1 - Where is the event?
Meaning - At what place is the event?
Example 2 - When is the event?
Meaning - At what point in time is the event?
In the first sentence, through the use of the word “where”, the question of what place the event will be at is raised. In the second sentence, the use of the word “when” raises an inquiry into what point in time the event will take place at. By keeping this simple distinction in mind, you will be able to identify obviously incorrect answer choices more easily and improve your efficiency on the GMAT sentence correction.
