Student-Produced Response (Grid-ins)

Roughly a quarter of the section. No choices — you compute the value and enter it under strict rules.

Grid-ins (officially “student-produced response”) give no answer choices: you work out the value and type it in. Because there is nothing to backsolve, accuracy and correct entry matter most. The format has firm rules — break one and a correct calculation still scores zero.

A grid-in entry showing 3/4, with the rules for valid entriesGrid-in (student-produced response)3/4or enter 0.753/4✓0.75✓75%✗1,000✗−3✗No percent signs, no commas, no negative grid-ins.
Enter 3/4 or 0.75 — never 75%, never a comma, never a negative.

The entry rules

  1. Enter fractions or decimals — both are accepted.3/4 and 0.75 are equally correct; you need not reduce 6/8.
  2. Drop percent signs — convert to a number.25% is entered as 0.25 or 1/4.
  3. Drop commas in large numbers.1,000 is entered as 1000.
  4. Never enter a negative — SAT grid-in answers are non-negative.If your answer is negative, recheck the question.

How to play them

A long decimal must fill the entry (don’t round early in a way that loses accuracy). If a problem has more than one valid answer, any one of them is accepted. And because there are no choices to lean on, verify before submitting — plug your value back into the original equation. A blank grid-in is a guaranteed zero, so always enter your best computed value, even when unsure.

💡
Decimals vs fractions: pick whichever is exact. 1/3 is exact; 0.33 is not — so on a one-third answer, grid 1/3.
