What AI gets wrong about the ACT science section

by | Apr 6, 2026 | AI, Test Prep

The ACT science section has a reputation it doesn’t deserve.

Students panic over it because it sounds hard. Parents worry their kid needs a chemistry refresher. Neither is the problem — because the science section isn’t really a science test. It’s a reading test with charts. That’s the whole thing. And yet AI manages to dance around this fact in ways that are, at best, incomplete, and at worst, actively misleading.

Three questions. Three answers. Here’s how it went. As always, we’ve included AI-generated summaries of each answer for readability. To see the full original responses, click here.

Note: We had a parent ask AI these questions on March 11, 2026. The answers have likely changed since then — hopefully for the better!

Question 1: What exactly is the ACT science section testing?

AI Summary

The ACT science section tests data interpretation and reasoning, not factual scientific knowledge.

  • Students encounter graphs, tables, experimental descriptions, and conflicting viewpoints
  • Questions ask them to analyze information and draw logical conclusions
  • Common tasks include identifying trends, comparing experimental results, and matching explanations to evidence
  • The section measures ability to process unfamiliar information quickly
  • Students comfortable reading charts, interpreting graphs, and spotting patterns tend to perform well
  • Reading comprehension and attention to detail matter as much as any science background

Wes’s Response

I call BS on this one.

The ACT science section is a reading test with a little scientific flavoring. It tests reading comprehension. The only real difference between the science section and the reading section — besides the fact that the topics are science, like cosplay science — is that it also requires you to read charts and graphs.

That’s its own skill. Kids should have it by now, and if they don’t, we teach it in prep. Not a big deal. But kids have conniption fits over it, and consequently they think the science section is something that it just isn’t.

Question 2: Does the ACT science section require actual knowledge of physics or chemistry?

AI Summary

The ACT science section does not require detailed knowledge of physics or chemistry.

  • The section focuses on interpreting information provided within the test itself
  • Graphs, tables, and short descriptions supply everything needed to answer questions
  • Students may see scientific terminology, but questions rely on logic rather than prior knowledge
  • Basic familiarity with scientific ideas can help, but isn’t necessary
  • Success depends on reading charts carefully and recognizing patterns, not memorizing facts

Wes’s Response

The correct answer is no. It does not.

To be really clear: there are often 1 or 2 questions — and I mean only 1 or 2 — that “require knowledge of physics or chemistry.” (Those are air quotes.)

What that actually means is that those questions contain a single word or phrase that’s easier to understand if you’ve encountered it before. But even then, critical reading skills can get you there.

This AI answer is somewhere between misleading and wildly misleading.

Question 3: Why do strong students struggle with the ACT science section?

AI Summary

Many strong students struggle with the science section because of its pace and unfamiliar format.

  • The section requires quickly interpreting multiple graphs and experimental descriptions
  • Even capable readers can feel overwhelmed by the volume of information
  • Questions often require comparing several pieces of data simultaneously, demanding rapid attention shifts
  • Some students waste time trying to fully understand the scientific context, which is usually unnecessary
  • Efficient test-takers focus only on the data needed to answer each question
  • Practicing with real ACT science sections helps students develop comfort with the format

Wes’s Response

This is a dumb question, because most strong students don’t struggle with it.

The AI’s explanations aren’t wrong — volume of information, spending too long on context, that’s all true. But those are problems that capable students have mostly solved by the time they’re taking the ACT.

If you’re a strong student struggling with the science section, the most likely explanation isn’t a reading gap. It’s that your school never taught you to read charts and graphs. Which is frustrating. And also, unfortunately, pretty common.

But that’s a rant for another day.


Here’s the thread: AI keeps treating the ACT science section like it’s about science. It isn’t. It’s about reading — including the specific skill of reading charts and graphs, which schools increasingly fail to teach.

That gap between what students think the section is testing and what it’s actually testing is exactly where scores get left on the table. It’s also exactly the kind of thing that’s fast to fix when someone points it out clearly.

AI, in this case, was not that someone.
