Understand the proper usage of the word "your/you're"

Understand the proper usage of the word you need. The best way to do that is to sound it out. There is a replacement test that will tell you for certain which word will fit. Read your sentence with "you are" in place of the "your/you're," intended. If it makes sense, then "you're" would be right. If not, then "your" would fit. You could also replace "your" with "my" in the sentence. If it fits, then use "your."
