ACT Science Practice Question Categories

ACT Science practice questions are split into three categories:

Data Representation (~25-35% of questions)

  • Interpreting Graphs: Practice reading and analyzing various types of graphs, charts, and tables.

  • Identifying Trends: Work on recognizing patterns and relationships in scientific data.

  • Extrapolation: Master predicting values beyond the given data range.

Research Summaries (~45-60% of questions)

  • Experimental Design: Practice understanding hypotheses, variables, and controls in experiments.

  • Interpreting Results: Work on analyzing experimental outcomes and drawing conclusions.

  • Comparing Experiments: Master identifying differences between related studies.

Conflicting Viewpoints (~15-20% of questions)

  • Comparing Theories: Practice analyzing different scientific explanations for the same phenomenon.

  • Identifying Disagreements: Work on finding points of conflict between different viewpoints.

  • Evaluating Evidence: Master determining which evidence supports which theory.


Effective Practice Strategies

To get the most out of ACT Science practice questions, we recommend the following strategies (they have been shown to help improve your score twice as fast!):

1. Start with Diagnostic Practice

Take a full-length practice test to identify your strengths and weaknesses. This helps you focus your study time on areas that need improvement.

2. Practice by Topic

Work through ACT Science problems by content area. Master one topic before moving to the next.

3. Time Your Practice

Always practice under timed conditions. Aim for about 52 seconds per question to build the pacing skills you'll need on test day.

4. Review Every Answer

Don't just check if you got the answer right. Read the explanations to understand the reasoning and learn new strategies.

5. Track Your Progress

Keep a record of your scores and note which types of ACT Science questions give you trouble. Focus extra practice on these areas.


ACT Science Test Format

Understanding the ACT Science test format is crucial for effective practice and test day success. The ACT has announced significant changes to the Science section starting in 2025, so it's important to know which version you'll be taking:

FeatureCurrent FormatEnhanced Format (Starting April 2025)
Required or Optional?Required (included as 1 of 4 sections)Optional (student choice to take it or skip)
Total Questions40 multiple-choice questions40 multiple-choice questions
Time Allotted35 minutes (about 52 seconds per question)40 minutes (about 60 seconds per question)
Passage TypesData Representation, Research Summaries, Conflicting ViewpointsSame passage types (no content change)

Understanding ACT Science Scoring

Each correct answer on the ACT Science section earns you 1 raw point. There's no penalty for wrong answers, so always guess if you're unsure.

Your raw score is converted to a scaled score from 1-36. The national average is around 20-21, while competitive scores are typically 25+.

Here are some key facts about ACT Science scoring:

  • No penalty for wrong answers – always guess

  • All questions are worth equal points

  • Science contributes 1/4 to your composite score (optional on enhanced test)

  • ACT offers superscoring across multiple test dates
