There are two testing dates to take the TEAS in December. I think there's more in January. I was planning on taking it in December but I started a new job, lots of homework, and been busy. I got the ATI official study guide from the college's library but only could have it for a week and it's due back Wednesday. I haven't studied at all. I'm so nervous for this test because it's really important. It gets me into nursing school! I was looking on amazon, eBay, Barnes and Noble looking to see what good study materials are (and cheap!) I don't want to buy the ATI for 40 to 50 dollars. What books really helped you to prepare/study? Should I wait until January? And what's it like to not use a calculator? I'm so nervous! Thanks in advance! :)
