My Daily Reflection Entry #2: Comma Usage

Today in class, I learned how to properly use commas.  I've learned have how to use them, but never really knew how to use them in certain sentences or why they needed to be used.  Using the correct punctuation in a essay is very imporant when taking the AP Exam.  Because you don't want to have a essay with run-on sentences, improper grammer, and incomplete sentences.  It is also important to use commas when they need to be used.
