To score an ACT practice test, count correct answers in each section, convert those raw scores with that form's scale table, then average English, Math, and Reading for your Composite. Do this every timed full-length so your baseline and progress stay honest.
Step 1: Grade each section
Use the answer key and mark every scored question right or wrong. Your raw score is the number correct. Leave blanks and wrongs as zero—there is no penalty either way. If the practice booklet flags experimental items (many official forms do not list them separately on released keys), exclude those from the raw count.
Step 2: Convert raw to scaled
Find the raw-to-scale chart for that practice form. Official ACT practice tests each ship with their own table. Look up your English raw score → scaled English (1–36), then do the same for Math and Reading (and Science if you took it).
Do not reuse a chart from a different form. Equating shifts slightly from test to test, which is why the same number correct can yield a different scaled score. For why that is not a classroom curve, see is the ACT curved.
Step 3: Average for Composite
Add the three scaled scores (English + Math + Reading), divide by 3, and round to the nearest whole number. Example: 29, 31, and 30 average to 30. Round .5 upward (31.5 → 32).
Official vs third-party practice
Official forms give the most trustworthy conversion. Third-party books and apps often use a generic scale; treat those composites as approximate. Prefer official practice for score-setting decisions, then dig into misses with the same rigor either way. Sources and review habits are in free ACT practice tests, official vs third-party tests, and how to review ACT practice tests.
What to do with the number
Log Composite and sections, note timing and content patterns, then set the next study block around your weakest section—not just the headline score. If you are aiming near perfection, also read how many questions you can miss for a 36.
The bottom line
Count correct, convert with the form's table, average three sections. A careful practice score beats a guess every time.
Start practicing
Start with a free diagnostic, then drill your weak spots with 15-question quizzes and track how you're doing across Reading, English, and Math. Compare plans whenever you're ready to go further.
