How skilled are you with writing? Do you want to test your abilities? Here you will be given a chance to practice your proofreading skills by correcting a given text.

Proofreading: Not Just for School!

Think of your English teachers from grade school. You likely had a new one every year, but there is probably one thing they all had in common…telling you to proofread your writing!

Proofreading, or examining one's writing for proper grammar and word usage, is a key element in every English class. However, most students don't realize that it's a skill you should use for the rest of your life.

Think about it. What if a salesman emailed you and used the wrong verb tense in every sentence? Would you buy his product? Probably not. We associate the correct use of our language with the person, and like it or not, make judgements based off of that. So how are you being judged based on your business writings?

Now you will be given a chance to proofread a profession email and correct all the errors. Think you can find them all? If you need a refresher first, check the lesson: Proofreading Your Message.
