SAT Grid-In Questions: Rules for Student-Produced Answers

A student produced response question gives you no answer choices. You solve it and type your answer into a box. Roughly 11 of the 44 Math questions work this way, which is about 25 percent of the section, and the exact count can shift slightly between forms.

They are not grouped at the end the way they were on the paper SAT. Expect them anywhere in either module.

The scoring is the same as everything else: right or wrong, nothing deducted for a wrong answer. What makes them different is that a correct value entered in the wrong format scores zero, which is a way to lose points you actually earned.

Integers, positive or negative. Negative answers are allowed on the digital SAT, and the minus sign takes one of the available characters.

Fractions, and they do not need to be reduced. If the answer is six eighths you can enter 6/8 and it is correct, as long as the whole thing fits in the box. Improper fractions are fine.

Decimals. If a decimal does not fit the box, truncate or round at the last digit that fits rather than rounding early. Rounding to two places when the box would hold more is how a correct answer becomes wrong.

Mixed numbers. There is no way for the app to tell one and a half from thirteen halves if you type 1 1/2, so convert to an improper fraction or a decimal.

Symbols. No percent sign, no dollar sign, no commas in large numbers, no units. If the answer is 1,250 dollars you type 1250. If the answer is 40 percent, read the question to see whether it wants 40 or 0.4, and type just the number.

Anything beyond one answer. When a question has more than one valid solution, the instructions say to enter only one. Typing two is wrong even if both are correct.

With no answer choices, you cannot backsolve and you cannot plug in the options. Two of the most useful multiple choice shortcuts simply do not exist here, which means you need the actual method.

Budget for that in your pacing. At about 95 seconds per Math question on average, a grid-in that takes two minutes is fine if the multiple choice questions around it took one. The average is what matters, not each individual question.

You also lose the sanity check that answer choices provide. On multiple choice, an answer that matches none of the options tells you something went wrong. On a grid-in, nothing tells you. Reread what the question asked for before you type.

Reread the last line of the question before entering. The SAT regularly solves for x and then asks for something built from x, and on a grid-in there are no choices to catch the mistake.

Check the units the question wants. If the setup is in minutes and the question asks for hours, the arithmetic can be perfect and the answer still wrong.

Always type something. There is no penalty for a wrong answer, so a plausible number costs nothing and occasionally lands, while a blank guarantees zero.
