"Pattern Recognition" is a commonly used term and a key skill for GMAT .By practice , I could observe clear patterns for right and wrong answers in RC and CR , but never in SC .I just observe splits/decision points and re-split after exclusion . Any advice ???

TheNona,

There are definitely patterns in SC - I would argue they are even more easy to spot than CR/RC ones. But you need to look at the questions and answer choices the right way.
Pay attention to structure, commas, -ING words, etc.

You're lucky to find these patterns easily in RC/CR - usually it's the other way around.

Here are two video examples you may find helpful:

Sentence Correction is really full all about learning patterns of errors. Here are a few random "patterns" off the top of my head:

Parallelism and Modifiers are the most common error types
The word "and" is a very important word (parallelism)
Splits usually happen at the beginning or end of underline or after punctuation
Commas related to parallelism or modifier questions
"Leading modifiers" are often used incorrectly
When a sentence is completely underlined it's likely to have modifier problems
It/its/they/them/their are often used incorrectly
Verbs at the start of underlined often lead to Subject/Verb errors

I could go on, but the real takeaway is that there a tons of patterns to be aware of for Sentence Correction. Perhaps you know these patterns already and just didn't recognize them as patterns. As you get really comfortable with SC and the error types, you will start seeing a lot of these errors, or patterns, in the original sentence (or when the original is correct you will see areas where the answer choices may be incorrect).

As I have found, common patterns for SC are:

I. Rules Tested

** Structure/ Meaning/Concision
All sentences must have a main subject and verb.
Avoid: Redundancy, Having Been/Being, Awkward Gerund Phrases, Introduction of New Pronouns

** Subject/Verb Agreement
The subject of the sentence must agree in number with the action it performs.

** Pronouns
A pronoun must not only agree in number with the noun it replaces, but it must also unambiguously refer to the noun it replaces.

** Modifiers
Modifying phrases must correctly modify the noun they refer to.

** Verb Tense
The verbs in a sentence should be consistent in their tenses, unless, of course, the meaning of the sentence requires otherwise.
If different actions are performed at different time periods, make sure the tense is consistent for each of them.

** Comparisons
Check for:
Unclear Comparisons
Illogical Comparisons

** Parallel Construction
The parts of a sentence should be similarly constructed.
The parallel structures should be grammatically, logically and idiomatically consistent.

** Idiomatic Expression
Technically not a grammar rule, idiomatic expression relates to using the accepted forms of phrases.

II. Few check points

** Occurrences of active and passive in the same question
** Countable and Uncountable
** Singular vs. Plural
** "Like" vs. "as" vs. "such as"
** "If" vs. "whether" vs. "whether or not"
** Word order: subject+ verb+ object+ complement
** Redundancy (to avoid)
