"Estimate .. ":

"Estimate NJ deer population to have grown" is UNIDIOMATIC.

In general,
"Estimate X to have VERB'ed" is WRONG.
"Estimate that X has VERB'ed" is RIGHT.

"Rather than" Vs "Instead of":

"Rather than" is preferable to use for VERBS.

"Instead of" is preferable to use for NOUNS.

In general, "FISH" is PLURAL.

If "Fish" is attached with articles such as "a" or "the", then it is SINGULAR.

papgust wrote:"Twice":

"Twice" CANNOT function as an object of the preposition such as "by".

"Twice" is an adverb.

Example:
"... increased by more than twice .." -- WRONG!

Courtesy: Ron Purewal, GMAT Expert.

On a similar note, "DOUBLE" is an adjective and cannot modify verb, but since "Twice" is an adverb it can modify Verb.
Example:-
The same amount of acreage produces double the apple.... -- WRONG
The same amount of acreage produces twice as many apples..... --CORRECT

I am on a break !!

"X was more concentrated than Y"

When Y uses a past tense, "was" (a past tense) must be used by X. MAINTAIN PARALLELISM b/w X and Y including TENSES.

"Maybe" and "Perhaps" are INTERCHANGEABLE.

"Perhaps" is slightly more formal.

"double what it was in 1977".

"what it was" is awkward, wordy and unclear according to GMAT standards.

AVOID DUPLICATION:

"... in the past would have conceded previously to rivals".

"Previously" repeats the idea of "in the past". WRONG!!

"In Japan, unlike the United States ... "

"In Japan" MUST be balanced by "in the United States" to maintain parallelism.

BUT, the preposition "in" CANNOT follow the preposition "Unlike". Therefore, this construction is ALSO awkward and imprecise.

"Contrast":

Correct idioms for contrasts:

* In contrast to X, Y
* In contrast with X, Y
* Unlike X, Y

-- X and Y must be grammatically and logically parallel.

Incorrect Idiom:

* As contrasted with X, Y

"X as much as Y" is a PROPER idiom.

"Not so much as" is another PROPER idiom used ONLY in the negative contexts.
E.g:
"Not so much as a whisper was heard from the crowd"

Incorrect Idioms:
* "So much/many as"
* "As much/many that"
* "So much/many that"

"Target Test Prep is the closest to the official version of the GMAT exam, about 99% accuracy in terms of the quality and quantity of information. The course has excellently created singular sets of focused lessons and tests for every possible topic that one could come across in the official GMAT exam."

"The TTP course maximizes the efficiency of the time you spend studying. It will take time and effort but I could almost guarantee that if you complete the course exactly as it is laid out you will get an amazing score. They also have a very responsive team willing to help with any questions you might have."

"TTP has two things that I think no other test prep company offers: A teaching approach that reinforces understanding and an attitude that will give you the mental preparedness needed to succeed on the test. TTP gives you a deep understanding of the concept you need to know while teaching you how to think."
