TEAS exam...Has anyone taken it?

My name is Cha and I'm a student at NWTC. Recently, they've added the TEAS exam onto the requirements for admission into the ADN program. Has anyone taken this exam before or has anyone ever heard of it? I'm not a very good "test taker" and am very nervous because I have to take the test in March and pass if I want to get into the ADN program this August. I panick everytime I think about it. If anyone has any hints or ideas on how to make this better or if anyone has taking this test before, I would surely be very thankful to hear a response.
