ACT Science without science: the figure-first method

You have an A in chemistry and a 24 in ACT Science, and the gap is not a knowledge gap. The section is a data-reading test with a science costume on, and the student who tries to understand each experiment the way they would in class runs out of time before the last passage. The method that fixes it is called figure-first: read the tables and graphs before anything else, go straight to the questions, and open the paragraph text only when a question sends you there.

This guide walks one passage figure-first with the clock running, so you can see where the minutes go and how many of the questions need any science at all. The passage and questions below are illustrative, written by us to show the structure. They are not ACT items.

The section, by the numbers

ACT, Inc. describes the format at act.org: the Science section is 40 questions in 40 minutes, it is optional since the 2025 test changes, and the passages come in three formats, Data Representation (a figure or two with a short description), Research Summaries (two or three related experiments) and Conflicting Viewpoints (two or more scientists disagreeing). ACT states that the section emphasizes scientific reasoning over recall, and its reporting categories are Interpretation of Data, Scientific Investigation, and Evaluation of Models, Inferences and Experimental Results. Interpretation of Data is the largest share, roughly 40 to 50 percent of the questions on ACT’s published blueprint [verify current percentages after the spring 2026 rebalancing].

One minute per question. With six or seven passages, that leaves about six to six and a half minutes per passage, including whatever reading you do. Three minutes of reading the introduction and method paragraphs leaves three minutes for six or seven questions, and that is how a strong student ends up guessing on the last passage.

The figures are where the answers live. Every Data Representation and Research Summaries question points, directly or indirectly, at a table, a graph or a sentence describing what was varied. Figure-first gets you to the source before you’ve spent anything.

The figure-first routine, timed

Same routine for every Data Representation and Research Summaries passage. Conflicting Viewpoints is handled separately below.

Forty-five seconds on the figures feels short. It’s enough, because you are not trying to understand the experiment. You’re building a map: which figure shows what, in which units, trending which way. The questions will tell you what to look up.

One illustrative passage, walked figure-first

Here is a Data Representation passage in the style of the section. Again, this is our own illustrative material, built to show the method.

Passage (illustrative). Dissolved oxygen (DO) is the amount of oxygen gas present in water, measured in milligrams per liter (mg/L). Researchers measured DO in a pond at several depths on three days when the surface water temperature was 10°C, 15°C and 25°C (Table 1). On a separate day, they measured surface DO every two hours from 6 AM to 6 PM (Figure 1). The probe was calibrated in air-saturated water before each measurement.

Table 1. DO (mg/L) by depth and surface temperature

Figure 1 (described). A line graph. The x-axis is time of day from 6 AM to 6 PM in two-hour steps. The y-axis is surface DO in mg/L from 6 to 12. The line starts at 7.4 at 6 AM, rises steadily to a peak of 11.1 at 2 PM, then falls to 9.0 by 6 PM.

Your 45 seconds. Table 1: depth down the side, temperature across the top, DO inside, in mg/L. Down any column, DO falls as depth increases. Across any row, DO falls as temperature increases. Figure 1: time across, DO up, one line, rises to 2 PM then falls. The probe-calibration sentence gets noticed, not studied. Clock: 0:45.

Now the questions, with what each one actually requires.

Question 1. According to Table 1, when the surface temperature was 15°C, the DO at a depth of 4 m was closest to: (A) 6.5 (B) 7.8 (C) 8.9 (D) 10.1.

Find the 15°C column, the 4 m row: 8.9. Answer C. Requires: reading one cell. Science knowledge: none. Time: 20 seconds.

Question 2. Based on Table 1, at each surface temperature, as depth increased from 0 m to 6 m, DO: (F) increased only (G) decreased only (H) increased, then decreased (J) remained the same.

Read down any column. Decreases every step. Answer G. Requires: spotting a direction you already noted in your 45 seconds. Science knowledge: none. Time: 15 seconds.

Question 3. According to Figure 1, surface DO was greatest at approximately: (A) 6 AM (B) 10 AM (C) 2 PM (D) 6 PM.

The peak you noted. Answer C. Requires: reading one graph. Science knowledge: none. Time: 15 seconds.

Question 4. Suppose DO had been measured at a depth of 8 m when the surface temperature was 25°C. Based on the trend in Table 1, the DO would most likely have been: (F) less than 4.9 mg/L (G) between 4.9 and 6.5 mg/L (H) between 6.5 and 7.6 mg/L (J) greater than 7.6 mg/L.

The 25°C column ends at 4.9 at 6 m and has been falling the whole way down. One more step would land below 4.9. Answer F. Requires: extending a trend one step past the table. Science knowledge: none. Time: 35 seconds.

Question 5. The researchers calibrated the probe in air-saturated water before each measurement most likely in order to: (A) increase the temperature of the pond water (B) ensure that the probe’s readings were accurate across measurements (C) remove dissolved oxygen from the probe (D) measure the depth of the pond.

This is the one question that sends you into the text, and only to the last sentence. Calibration, in any field, means checking an instrument against a known standard so that readings are trustworthy. Answer B. Requires: reading one sentence and knowing what the word calibrate means. Science knowledge: none beyond general vocabulary. Time: 40 seconds.

Question 6. Algae in pond water release oxygen through photosynthesis, which requires sunlight. Based on this information and Figure 1, the increase in surface DO between 6 AM and 2 PM is most consistent with which of the following? (F) Algae consumed oxygen as sunlight increased. (G) Algae released oxygen as sunlight increased. (H) Oxygen left the water as it warmed. (J) The probe lost calibration over the morning.

The science fact is handed to you in the first sentence of the question. Sunlight rises through the morning, algae release oxygen in sunlight, DO rises. Answer G. Requires: applying a fact given in the stem to a graph you’ve already read. Prior science knowledge: none. Time: 45 seconds.

Clock at the end: about 3:35 for the questions, plus 0:45 for the figures, call it 4:20 with a bubble check. Two minutes under budget on a passage of this type is normal with the method, and that surplus is what pays for Conflicting Viewpoints.

Count it up. Six questions, five answered from the table and graph alone, one from a single sentence of text, and zero requiring anything you learned in chemistry. A real ACT section will include a few questions that do require a remembered fact. The method doesn’t make those go away, but it means they’re the only places you’re spending real thought.

Where the text actually matters

Figure-first does not mean never read. It means read on demand, and there are three predictable triggers.

A question that says “according to the passage” or “the researchers’ hypothesis was” is pointing at the introduction, usually one specific sentence. Go find it.

A question about why a step was done (Question 5 above) or what would happen if a step were changed is about the method. In Research Summaries passages, each experiment’s description has one sentence that states what was varied and one that states what was held constant; those two sentences answer almost every method question.

A term you can’t find on any figure, or a unit conversion the figure doesn’t show, means a definition is hiding in the text. Scan for the word in italics or in the first paragraph.

Everything else stays unread. On a Research Summaries passage with three experiments, you will typically read three or four sentences of text total, and only after a question asks.

Conflicting Viewpoints: the exception

One passage per section presents two or more scientists, students or hypotheses disagreeing, with little or no data. There is no figure to go first to. You have to read.

Budget eight minutes for it, taken from the surplus the other passages produce. Read each viewpoint once and write a three-to-six-word summary of its central claim in the margin (“Scientist 1: comet impact caused the layer”). Then go to the questions. Most ask what one viewpoint would say about a new piece of evidence, or where exactly the viewpoints differ. Your margin summaries answer the first kind; a quick re-read of the specific sentence answers the second.

Decide now whether this passage goes first or last. Doing it first means you read it fresh, at the cost of starting the section slowly. Doing it last means your figure-first surplus is already banked, at the risk of rushing it. We usually recommend last for students who finish the other passages under budget and first for students who get anxious when a passage looks long. Try both on practice sections and keep the one that scores better.

Find it, decide, don’t dither.

Why a 24 usually means time, not accuracy

Students at 24 who are strong in science class share a pattern on their practice tests: high accuracy on the first four passages, then a run of blanks or guesses on the last two. Their raw score is being set by the clock. Check your own last practice section. If your wrong answers cluster at the end, you are in this group, and figure-first is the fix.

If the misses are spread evenly across the section, the issue is different. Usually it is reading too much into trend and extrapolation questions, or choosing the answer that is scientifically true in general over the answer the figure supports. The section rewards literal reading. An answer that is true in the world but not shown in the data is wrong on the ACT.

Drilling it

Use official ACT practice material only; the figure conventions matter and third-party passages often don’t match them. Start with single passages, not full sections.

The log is the point. Drilling without it teaches your hands to move faster. Drilling with it shows you, in your own numbers, that the paragraph text was costing time and buying nothing, and that is the conviction that holds on test day when the first passage looks intimidating.

What to do this week

1. Pull your most recent practice Science section and mark where the misses sit. Clustered at the end means a pacing problem; spread evenly means a reading problem. The method helps both, but the first group gains fastest.
2. Run two official Data Representation passages tomorrow with a 6:00 timer, figures first, and log for each question whether you read any paragraph text.
3. Write your 45-second figure map out loud on the first few passages: title, axes, units, direction. Saying it slows you down enough to actually do it.
4. Pick first or last for Conflicting Viewpoints, and try the other on the following practice section so you have a comparison.
5. Bring the log to your first session, or review it yourself against the question types above: the pattern in the “yes, I read the text” column is where your 24 is coming from.
