The hardest ACT Science questions combine multiple figures, test experimental design flaws, ask you to predict outcomes, or require deep inference on Conflicting Viewpoints—this is where 34-scorers usually lose the last points toward a 36. Isolate these types in practice. Part of how to get a 36 on ACT Science.
Multi-figure synthesis
One question references Figure 1 and Table 2, or asks you to compare results across two experiments. Read each figure once, write one line linking them, then answer. Do not hold both in memory without notes.
Design-flaw and "what if" questions
Which change would make the experiment invalid? What result would disprove the hypothesis? These test whether you understand variables and controls—not recall. Review experimental design questions and Research Summaries passages.
Predicting outcomes
If the independent variable doubled, what would happen to the dependent variable? Use the trend shown in the data; do not invent a mechanism. Trend skills in interpreting trends.
Conflicting Viewpoints inference
Which new evidence would most weaken Viewpoint 3? These require precise comparison, not skim reading. Strategy in Conflicting Viewpoints on ACT Science.
Interpolation under time pressure
Estimating between points when the graph is crowded or uses an unusual scale. Drill in interpolation and extrapolation.
How to train them
After each full Science section, tag misses by type—not just "Science." Do extra reps on the one or two types that appear most. Avoid repeating mistakes in common ACT Science mistakes.
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.
