I would hope that they wouldn't have 2 answer choices that are off by only a decimal point or two, but I could be wrong. You should be able to get an answer close enough where you can easily identify the right one (even if it's off from your calculation by a couple decimal points). I usually use 3 or 4, and so far no problems with finding the right answer on any practice questions. |
