The single-answer multiple-choice questions are pretty basic; you've been answering these questions for years. But, the multiple-answer questions are a little bit more complicated. These questions sometimes tell you how many answers to pick, and sometimes leave that up to you.
You only get credit for multiple-answer questions if you choose all of the correct answers and none of the incorrect answers. Your answer has to be exactly right to get any credit. For example, if the correct answer is A, C, and F, you can only get points for picking exactly those three. You don't get partial credit for picking A and C, or A, C, and D. It has to be A, C, and F.
Here are some strategies for the multiple-choice questions:
• - Use elimination. If you're struggling on a question, write down all the answer choices on your scrap paper and cross off the ones you know are wrong.
- Guess even if you don't know. There's no guessing penalty on the GRE, so you can only help yourself by guessing.
- Pay attention to what type of question you're answering. But if you get a 'one or more' correct answer question without a number of answers specified, don't freak out if you pick just one. 'One or more' means it's possible that only one of the answers is correct!
- Don't be afraid to save hard questions for later. You can mark questions for review and come back to them at the end.
- Look for patterns. Seeing patterns in your work or in the answer choices can help you skip long and complicated calculations.
- Use the answer choices to help you. For example, sometimes it's simpler to plug each answer choice into an equation, instead of solving the equation to find every possible answer. Also, sometimes the answer choices are obviously estimations. If that's the case, you can sometimes use estimated numbers in your calculations and save yourself a bunch of fiddly arithmetic.
Numeric Entry
The next question type is numeric entry. On numeric entry questions, you'll have to generate your own answer and enter it in a box. If the correct answer is a fraction, you'll get two boxes, one for the numerator and one for the denominator. The test is computerized, so there's no worrying about handwriting, but here's the fine print you need to know to make sure you get credit for your work on these questions:
- Be as precise as possible unless the question specifically asks you to round.
- You can enter negative numbers using the hyphen. If you remember taking the SAT, you might remember that you couldn't have a negative answer for the free response section. That's not true on the GRE.
- Equivalent forms of the same answer are all right. For example, 2/4, 1/2, 0.5, and 0.50 would all be equally correct answers.
Some strategies for numeric entry questions are:
- Write down your work on your scrap paper, and mark it with the question number. This will help you if you need to check your answer later, or if you save a question to work on at the end of the section. If your work is neatly organized, it's easy to go back and check your logic.
- Make a guess if you have one. With the numeric entry questions, random guessing is rarely helpful since your chances of guessing right are very low. But, there's no wrong answer penalty, so if you have even an idea, go ahead and put it down.
- Just like the multiple-choice, don't be afraid to save hard questions for later. You can mark questions for review and come back to them at the end.
Lesson Summary
In this lesson, you learned about three question types on the GRE Quantitative Reasoning measure:
- Multiple-choice with one answer
- Multiple-choice with one or more answers, and
- Numeric entry, where you write in your own answer
You'll get these questions all mixed up together in the math sections. To help make them easier, use your scrap paper. Your scrap paper can help you eliminate answers on the multiple-choice, and keep track of your work on the numeric entry. Remember that you can save questions for later, and don't be afraid to skip the hard ones and move on. There's no guessing penalty, so guess for all the multiple-choice and every time you have even an idea for the numeric entry questions. It can only help you! Avoid complicated calculations when possible by recognizing patterns, looking at answer choices to see if you can use estimated numbers, and using the answer choices to help you. Sometimes it's easier to work backwards from the answer choices.
