Congratulations on completing the second course of our curriculum on writing effectively, and welcome to our third and final course: commas, perhaps the most important lesson offered by Textbroker University. You are almost done with the instructional part of our program and can soon begin writing orders for your re-evaluation!

While many people think that comma mistakes are a minor nuisance, comma use is often the biggest difference between a 3- and 4-star rating—and therefore is a determining factor in how much money an author can earn. To illustrate the importance of commas, just think of the following example: It’s one thing to say, “Let’s eat, Grandma!” and quite another thing to say, “Let’s eat Grandma!” Fortunately, comma problems are easy to fix once you know the basics. For those of you who were ever turned off of grammar and punctuation in high school because your monotone teacher with thick glasses and bad hair diagrammed sentences until you fell asleep and dreamed of the comma police, Textbroker University has simplified the world of commas into an easy-to-follow video presentation that will have you mastering commas in no time.

Please review the following video:

What is the difference between dependent and independent clauses?

Confused? You can always watch the video again or skip to particular parts. As always, feel free to contact Author Services at with any questions!
