ACT Science

The ACT Science section doesn't test memorized science facts—it tests how well a student can read a graph, follow an experiment's design, and judge whether a claim is actually supported by the data given. Passages draw on biology, chemistry, earth and space science, and physics, but a student doesn't need outside content knowledge in any of them to do well; everything needed is in the passage itself.

One-on-One Support for the ACT Science Section

Since Science is now an optional section, it’s worth deciding early whether adding it fits a student’s goals. Our tutors at Growing Stars build a plan around exactly what each student needs to work on, based on their current comfort level with data and scientific reasoning and their target score, rather than reviewing everything equally. Sessions walk through each skill clearly, using real practice questions, so students build both the reasoning skills and the speed needed to finish comfortably.

Our tutors focus on reading data quickly and accurately, understanding experimental design, and practicing under the section’s real-time pressure.

Skills & Course Focus

Whichever skill needs the most attention, sessions are matched to the exact sub-topics within each domain:

  • Interpretation of Data (38–50% of the section): Reading values directly from tables, graphs, and diagrams; identifying patterns and trends; translating information between formats; and applying basic math reasoning to data.
  • Scientific Investigation (18–32% of the section): Identifying independent and dependent variables, understanding controls, comparing multiple experiments, and predicting how a result would change under different conditions.
  • Evaluating Scientific Arguments and Models with Evidence (25–35% of the section): Comparing conflicting viewpoints or models, judging the strength of evidence behind a claim, and drawing conclusions that go beyond the data explicitly given using a claim-evidence-reasoning approach.

Test Overview

  • Status: Optional. A Science score is reported separately from the Composite score, though some colleges may consider it or prefer it for certain programs.
  • Structure: 40 questions total (34 scored, plus 6 unscored questions embedded for field-testing that aren’t identified to the student).
  • Passage Types: Passages draw on biology, chemistry, earth and space science, and physics, typically presented as data representation, research summary, or conflicting viewpoints passages.
  • No Outside Knowledge Required: Questions are answerable using only the information provided in each passage, not memorized science facts.
  • Not Adaptive: Every student answers the same fixed set of questions in the same order.

Exam Format

Format and content below reflect the Enhanced ACT, which rolled out nationally by September 2025 and is the current version as of August 2026. ACT, Inc. may continue to refine details, so we recommend confirming the latest details on the official ACT Science page before test day.

  • Duration: 40 minutes for 40 questions, given after the three required sections for students who sign up for it.
  • Scoring: 1–36 for the Science section, reported separately from the Composite score. There is no penalty for incorrect answers.

Why Families Choose Growing Stars for ACT Science Test Prep

At Growing Stars, we know that every student’s comfort with data and scientific reasoning is different. Our expert tutors personalize each session to the student’s goals and current comfort level, rather than following a fixed script.

Sessions are built around official-style practice questions and full-length practice tests, supported by our library of data-interpretation drills and experimental-design practice. Because sessions are one-on-one, tutors can spend as much time as needed on the skill causing trouble—whether that’s reading a graph quickly, identifying the variable in an experiment, or judging which of two scientists’ viewpoints the data actually supports.

Sessions take place online, so students can join from home, a study space, or anywhere with an internet connection.
