If you will be taking a standardized test, such as TEAS, HESI, or NLN, you better know how to use the rules. Not knowing them, no matter how we speak in everyday life, could mean you can't pursue the career training you choose. Forget about them the day after you pass the test, but know them during that 30 minute period. In real life, simply say, "This is (your name)." It's correct by anyone's standards.
