An estimate, not an official score. ACT equates every test form separately. These conversions are the median of ACT's own published scoring tables for its four official enhanced practice tests, the same tables our free ACT practice tests use.

Free ACT practice test1-on-1 ACT tutoringHow the enhanced ACT is scored
Since 2025 the ACT has three required sections, English (50 questions, 35 minutes), Math (45 questions, 50 minutes) and Reading (36 questions, 40 minutes), plus optional Science (40 questions, 40 minutes) and Writing.
Each section gets a scale score from 1 to 36. Your composite is the average of English, Math and Reading, rounded to the nearest whole number (halves round up). Science no longer counts toward the composite; if you take it, you also get a STEM score, the average of Math and Science.
Some questions in each section are unscored field-test items: ACT's practice tests score 40 of 50 English, 41 of 45 Math, 27 of 36 Reading and 34 of 40 Science questions. If you counted every question, the calculator scales your count onto the scored range before converting it.
How to use it
- Count your correct answers in each section of a full practice test. Blank answers count as wrong; there is no guessing penalty.
- Choose whether you counted every question or only the scored ones (an official answer key marks which are scored).
- Read your estimated section scores, composite and STEM score.

Frequently asked questions
How is the ACT composite score calculated?
On the enhanced ACT, the composite is the average of your English, Math and Reading scale scores, rounded to the nearest whole number with halves rounding up. Science is reported separately and is part of the STEM score instead.
Does Science count toward the ACT composite?
Not on the enhanced ACT (2025 and later). Science is optional; if you take it, you get a Science score and a STEM score (the average of Math and Science).
How many questions are on the ACT?
English 50, Math 45 and Reading 36, plus 40 in optional Science. Some questions in each section are unscored field-test items.
Is this ACT score calculator accurate?
It is a close estimate. The conversions come from ACT's own published scoring tables for its official enhanced practice tests, but ACT equates every test date separately, so a real test's scale can differ by a point or two.
Is there a penalty for guessing on the ACT?
No. Only correct answers count, so answer every question.
