2ndLife 63 Posts Aug 14, 2009 I did okay on the TEAS even though it had been a while since I had taken any math, science or english classes. Oddly enough, even though I have a B.S. in biology, the science was the hardest part for me because it was so long ago. When I studied, I just skimmed the physical science stuff and that's what hurt me most. I'm sorry, but I never was too excited about velocity, amps, ohms and electrical currents. I bought one study guide and got others from the library to get more practice.
