A note about Grid-ins
The method for PSAT math questions
PSAT math

You will see an occasional question without answer choices throughout the Math chapters of this book, starting in the next chapter. On the PSAT, several of these Grid-in questions appear at the end of each Math section. Instead of bubbling in a letter, you’ll enter your responses to these questions into a grid that looks like this:

If you are gridding a value that doesn’t take up the whole grid, such as 50, you can enter it anywhere in the grid as long as the digits are consecutive; it doesn’t matter which column you start in. Gridding mixed numbers and decimals requires some care. Anything to the left of the fraction bar will be read as the numerator of a fraction, so you must grid mixed numbers as improper fractions. For instance, say you want to grid the mixed fraction . If you enter 5 1/2 into the grid, your answer will be read as . Instead, enter your response as 1 1/2, which will be read (correctly) as . Alternatively, you could grid this answer as 5.5.

A repeating decimal can either be rounded or truncated, but it must be entered to as many decimal places as possible. This means it must fill the entire grid. For example, you can grid as .166 or .167 but not as .16 or .17.

Note that you cannot grid a minus sign or any value larger than 9,999, so if you get an answer that is negative or larger than 9,999 to a Grid-in question, you’ve made a mistake and should check your work.
