Why Proofreading Is Important  Proofreading is checking a draft
when it is almost ready to turn in. When proofreading, you are
only checking for minor errors, such as spelling, punctuation,
or grammatical errors. Although it is one of the last issues
addressed in writing a paper, it is an essential part of the
writing process.  Common Grammar Errors  Tense Shifts Passive vs
Active Sentences Misspelled and Dangling Modifiers Lack of
Parallelism Incomplete Sentences Run on Sentences  Pay attention
to specific errors you detect and make a note of which errors
occur most frequently so that you know what to look for in your
writing. Everyone has strong and weak areas, and all writers
improve when they make a consistent effort to be aware of their
weaknesses.  Also See:  Proofread Revise Polish  When to
