I totally have test anxiety and a learning disability and I will have to say that the TEAS was a challenge for me. I preferred to take it paper and pencil over on the computer. I would ask which one you would be taking.
I found that for the math section, you really need to be up on your fractions, know your math skills at the drop of a hat! You get almost 1 min per question and it really is not enough time for some of them. Go through them and get the really quick ones out of the way and then go back for the second round that will take you more time. Last do the ones that you really have to write down and figure out. The math section was really challenging for me because it was timed and I have a visual processing problem that causes me to read the numbers wrong. If I get a min to really look at it then I am good but in this case, practice your math skills!
The rest of the test was pretty easy, the English comprehension and spelling section was a breeze if you speak English as your 1st language. The science section was a variety of interesting subjects, study the earth science and physics questions!
Good Luck!
Even though I am not a good test taker I was able to get a decent score. Just be prepared as much as possible and take your time when you do get it!
