Hi All!
I'm astonished how easy persons here solve the tough problems. Can you share effective strategy of cracking CR question?
Personally, at first, I try to eliminate wrong answers, but finally I have at least two options usually

Many of the problems are "deductive" in nature and use strict logic.
In these the conclusion MUST be true.

You must understand a few simple rules of logic such as:

If P then Q is true
Given P then Q.
or given NOT Q then NOT P.

Also, you must be able to translate English into logic.

Q only if P
if P then Q
All P is Q

some tricky ones are:

P unless Q (equal to if not Q then P)
P is necessary for Q
P is required for Q

Simple diagramming techinques are very helpful here.

A decent GMAT prep book should steer you in the right direction.

The other type in Inductive reasoning. In this type, you form your conclusion based on the strength of favorable evidence.

You must learn to recognize how various premises support and undermine your premise.

Sorry guys,
I meant strategy for SCs, not for CR

But anyway, thanx!

Look for the following:

Pronoun errors: (agreement, reference, and case)
Modifier errors: (agreement, reference)
Comparison errors: (agreement, reference, parallelism, "apple to apples")
Verb tense errors: (correct tense, correct relative tense)
Subject/Verb Agreement (sing/plural)
Parallel STructure
Idiomatic forms/Use of wrong words
Other: (punctuation, redundacy, style, active/passive, conciseness, etc).

You need to create a system to go through the above list.
My system varies from sentence to sentence but for a complex sentence I always look for parallel structure first, then agreement, reference, tense, then the rests...

Sentence correction lends itself well to POE.

AkamaiBrah,

pretty good. Do you eliminate wrong answers first or try to find correct one once?
