Patterns in SC ????

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).
