Just study the manual and you will do just fine. I'm an older student too and took the TEAS last week. I was really nervous and couldn't fall asleep the night before the test. I studied the manual, especially the math and science and it totally prepared me for the test. I also took the online practice exam and it was really helpful. It's only 100 questions but is set up exactly like the real test. Anyway, I passed with flying colors just by studying the manual. I had to review all the algebra, geometry, fractions and percentages. I stressed way to much and found the test to be quite easy.
