Step 6: Know When to Guess

Armed with the process of elimination, you’re ready to take control of one of the big questions in test-taking: Should I guess? The first and main answer is yes. Unless the exam has a so - called “guessing penalty,” you have nothing to lose and everything to gain from guessing. The more complicated answer depends both on the exam and on you—your personality and your “guessing intuition.”

Most dental assisting exams don’t use a guessing penalty. The number of questions you answer correctly yields your score, and there’s no penalty for wrong answers. So most of the time, you don’t have to worry— simply go ahead and guess. But if you find that your exam does have a guessing penalty, you should read the section below to find out what that means to you.

How the Guessing Penalty Works

A guessing penalty really only works against random guessing—filling in the little circles to make a nice pattern on your answer sheet. If you can eliminate one or more answer choices, as outlined above, you’re better off taking a guess than leaving the answer blank, even on the sections that have a penalty.

Here’s how a guessing penalty works: Depending on the number of answer choices in a given exam, some proportion of the number of questions you get wrong is subtracted from the total number of questions you got right. For instance, if there are four answer choices, typically the guessing penalty is one - third of your wrong answers. Suppose you took an exam of 100 questions. You answered 88 of them right and 12 wrong.

If there’s no guessing penalty, your score is simply 88. But if there’s a one - third point guessing penalty, the scorers take your 12 wrong answers and divide by three to come up with four. Then they subtract that four from your correct answer score of 88 to leave you with a score of 84. Thus, you would have been better off if you had simply not answered those 12 questions. Then your total score would still be 88 because there wouldn’t be anything to subtract.

What You Should Do About the Guessing Penalty

You now know how a guessing penalty works. The first thing this means for you is that marking your answer sheet at random doesn’t pay. If you’re running out of time on an exam that has a guessing penalty, you should not use your remaining seconds to mark a pretty pattern on your answer sheet. Take those few seconds to try to answer one more question right.

But as soon as you get out of the realm of random guessing, the guessing penalty no longer works against you. If you can use the process of elimination to get rid of even one wrong answer choice, the odds stop being against you and start working in your favor.

Sticking with our example of an exam that has four answer choices, eliminating just one wrong answer makes your odds of choosing the correct answer one in three. That’s the same as the one-out-of-three guessing penalty—even odds. If you eliminate two answer choices, your odds are one in two—better than the guessing penalty. In either case, you should go ahead and choose one of the remaining answer choices.

When There Is No Guessing Penalty

As noted above, most dental assisting exams don’t have a guessing penalty. That means that, all other things being equal, you should always go ahead and guess, even if you have no idea what the question means. Nothing can happen to you if you’re wrong. But all other things aren’t necessarily equal. The other factor in deciding whether or not to guess, besides the guessing penalty, is you. There are two things you need to know about yourself before you go into the exam:

  • Are you a risk - taker?
  • Are you a good guesser?

Your risk - taking temperament matters most on exams with a guessing penalty. Without a guessing penalty, even if you’re a play - it - safe person, guessing is perfectly safe. Overcome your anxieties, and go ahead and mark an answer.

But what if you’re not much of a risk-taker, and you think of yourself as the world’s worst guesser? Complete the worksheet Your Guessing Ability on the next two pages to get an idea of how good your intuition is.
