As in writing essays questions, good grammar and punctuation are a must. Most students use word processors to write papers. Be sure to use the spell and grammar checks that almost all word processors have built in. HOWEVER...a computer is not human! Therefore, you can not and should not solely rely on the computer. You must also be an active proofreader and read through, out loud, your essay/paper. Many spelling and grammatical errors will jump out at you if and when you read the paper aloud.
