The passages are not in order of difficulty, so what order should you attempt them in?
Ordering the passages on ACT Science: attempting the fast figure-driven passages first to bank points and time, then the reading-heavy Conflicting Viewpoints passage, since the test is not arranged by difficulty.
A focused answer on choosing an attack order for ACT Science passages: the section is not in difficulty order, so many students bank the quick figure-driven passages first and save the slow Conflicting Viewpoints passage, while bubbling answers on the real answer sheet to avoid misnumbering.

What this topic is asking
A useful fact about ACT Science is that the passages are not arranged from easiest to hardest. A slow, reading-heavy passage can appear first, and a quick figure passage can appear last. That means you can often score more by choosing your own attack order: banking the fast passages first to secure points and build a time cushion, then tackling the slow one. This page sets out how to triage the passages and the one safeguard reordering requires.
The section is not in difficulty order
Some test sections run easy to hard, but ACT Science does not order its passages by difficulty. The format of a passage (Data Representation, Research Summaries, Conflicting Viewpoints) is a far better guide to how long it will take than its position. So the slowest passage might be Passage 1, and an easy figure passage might be Passage 6. Recognising this frees you to not simply work straight through.
A common, effective order
Many high scorers use a simple triage:
- Do the figure-driven passages first. Data Representation and the data-heavy Research Summaries passages are usually the fastest and most mechanical, so doing them first banks points while you are fresh and builds a time cushion.
- Save Conflicting Viewpoints for a planned slot. Because it reads slowly (see the reading-heavy passage strategy), take it after the quick passages, using the cushion you built.
An alternative some prefer is to do Conflicting Viewpoints first, while their reading is freshest, then the figure passages. Either is fine; what matters is that you choose deliberately rather than meeting the slow passage by surprise mid-section. The point connects to the overall budget in pacing the 40-minute section.
Triage within your order
Even within a chosen order, you can skip a stubborn passage or question and return. If a passage looks unusually dense or a question stalls you, move on, bank the easier points elsewhere, and come back with leftover time. Because there is no guessing penalty, anything you cannot reach still gets a guess at the end. Triage protects you from sinking minutes into one hard passage while easy points wait.
The safeguard: bubble in the right row
The one real risk of reordering is misnumbering the answer sheet. If you skip Passage 1 and start bubbling at Passage 2's questions, it is easy to put answers in the wrong rows, which can shift every later answer and quietly destroy your score. The safeguard:
- Match each answer to its question number on the answer sheet, every time.
- When you skip a passage, leave its rows blank and fill them when you return.
- Glance at the question number before bubbling, especially right after a skip.
A careful bubbling habit makes reordering safe; a careless one makes it dangerous.
Try this
Q1. Are ACT Science passages arranged from easiest to hardest? What should you use to judge how long a passage will take? [2 points]
- Cue. No; use the passage format, since figure-driven passages (Data Representation, much of Research Summaries) are usually faster and Conflicting Viewpoints is usually slower.
Q2. What is the essential safeguard when you attempt the passages out of printed order? [2 points]
- Cue. Bubble each answer in its correct numbered row (leaving skipped rows blank until you return), so reordering does not misalign and shift every later answer.

ACT Science (style)1 marksUnlike some sections, ACT Science passages are generally: (A) arranged strictly from easiest to hardest. (B) not arranged by difficulty, so a hard passage can come early. (C) all exactly equal in difficulty. (D) ordered alphabetically.Show worked answer →
A 1-point item underpinning the ordering strategy.
The correct answer is (B). ACT Science passages are not ordered by difficulty, so a slow Conflicting Viewpoints passage might appear first and a quick Data Representation passage last. (A) and (D) are false, and (C) ignores that the formats differ in difficulty and speed. Because the order is not by difficulty, choosing your own attack order can help.
ACT Science (style)1 marksIf you skip a hard passage to do an easier one first, the most important safeguard is to: (A) answer in your head only. (B) carefully bubble each answer in the correct numbered row on the answer sheet. (C) skip bubbling until the end. (D) change your calculator settings.Show worked answer →
A 1-point item on the risk of reordering.
The correct answer is (B). Jumping between passages means your answers are out of printed order, so you must make sure each answer goes in the correct numbered row to avoid a misalignment that shifts every later answer. (A) and (C) invite errors, and (D) is irrelevant. The benefit of reordering is lost if the bubbling slips.
