Do not go into the test session with a "Plan B" (i.e., what if you fail); go in with only "Plan A", and that is to pass the test and be on the air in the near future. This is not arrogance, but rather confidence, which comes from studying the material in a way that works best for you. Also, do not change your answers - many people most often change them from correct to incorrect. Read the question while covering the answers with enough paper to obscure them, and think about how you would answer that question, then see which of the answers most closely matches your thought. Usually two (or three) of the answers are really goofy, and the fourth (not necessarily in that order, of course
) possibility is the real deal.
A bit of help may come from "
Uncle Jerry's Law of Abilities", which states that,
if I can do it, you can do it. I mention this to my students in every class that I teach.
