I wouldn't worry too much, recruiters usually give you a test before the actual test and if you fail you can come back in a week or two.
The old father of lies was clever at telling half-truths: How shall you "know" good and evil, until you shall have sampled a little? Taste and be as Gods. But neither infinite power nor infinite wisdom could bestow godhood upon men. For that there would have to be infinite love as well.
