SAT vs. ACT: Understanding the Difference — And Which One Is Right for Your Student

One of the most common questions I get from families — especially homeschool families navigating the college process without a school counselor — is this: “Do we need to take both the SAT and the ACT? How are they different? Which one should my kid focus on?”

Great questions, all of them. Let me break it down in plain English so you can make a smart decision for your student.

The Short Answer First

Both the SAT and the ACT are college admissions tests accepted by virtually every four-year college and university in the United States. You do not have to take both — one strong score on either test is enough for most applications. The question is: which test plays to your student’s strengths?

How Are They Different?

The ACT and SAT test similar skills — reading, writing, and math — but they do it differently. Here are the key differences families need to understand.

Structure and Sections

The SAT has two sections: Reading & Writing (combined) and Math. Clean and simple.

The ACT has four sections: English, Math, Reading, and Science. There’s also an optional Writing (essay) section that most schools no longer require, though some still do.

That Science section on the ACT trips a lot of students up. Here’s the thing: the ACT Science section is not really a science test. It doesn’t test whether your student knows chemistry or biology. Instead, it tests data interpretation — reading graphs, analyzing experiments, comparing studies. It’s more like reading comprehension with charts. But students who haven’t seen it before often panic. Knowing what’s coming makes a huge difference.

Time Pressure

The ACT is faster-paced. Students have less time per question on the ACT than on the SAT across every section. For students who work carefully and methodically, the SAT’s pacing can feel more manageable. For students who are quick and confident, the ACT’s pace isn’t a problem.

This is one of the most important factors in figuring out which test fits your student better.

Math Content

Both tests cover algebra, geometry, and data analysis. The ACT goes a bit further — it includes more trigonometry and some topics like matrices and logarithms that the SAT largely avoids. If your student has taken Algebra 2 and is comfortable with a wider range of math topics, the ACT math section might not faze them. If they’re stronger in foundational algebra and data reasoning, the SAT’s math section may be a better fit.

Reading Style

The SAT Reading & Writing section asks students to work with evidence from passages — citing specific lines, connecting information across multiple texts. It rewards careful, analytical reading.

The ACT Reading section is more straightforward: read four passages, answer questions about what you read. It rewards reading speed and comprehension. Some students who struggle with the SAT’s evidence-based format do much better on the ACT’s more direct reading questions — and vice versa.

Scoring

The SAT is scored on a scale of 400–1600 (800 per section, two sections).
The ACT is scored on a scale of 1–36, with a composite score that averages the four sections.

These scores don’t directly convert to each other, but there are concordance tables that let you compare. A 1200 on the SAT is roughly comparable to a 25 on the ACT. Both are solid scores, and either can qualify students for significant scholarship opportunities.

How Do You Figure Out Which One to Take?

The best way — honestly, the only reliable way — is to take a full practice test of each under real testing conditions and compare the results. Khan Academy offers free official SAT practice tests, and ACT.org provides free ACT practice tests. Take one of each, score them, convert to the same scale, and see where your student comes out higher.

Some general tendencies that can help you guess before testing:

• Students who are strong readers and do well with analytical tasks often prefer the SAT.
• Students who are quick workers and don’t mind jumping between different types of content often do better on the ACT.
• Students who have covered more advanced math (trig, Algebra 2) have a slight advantage on the ACT.
• Students in Southern and Midwestern states have historically leaned toward the ACT — it was the dominant test in this region for years.

A note for Georgia families: Georgia colleges like UGA, Georgia Tech, and Kennesaw State accept both tests, but many of their scholarship thresholds are published in ACT score terms. It’s worth checking the specific scholarship criteria for the schools your student is considering.

Can They Take Both?

Absolutely — and many students do. If your student has the time and energy, taking both tests and submitting the stronger score is a perfectly valid strategy. Colleges do not penalize students for submitting only one test, and most schools accept whichever score you send.

If your student takes both and scores similarly on both, submit both — it shows versatility and doesn’t hurt anything.

What Good ACT Prep Actually Looks Like

Because the strategies are a bit different from SAT prep, here’s what effective ACT preparation actually involves:

Start with the Science section. It’s unfamiliar to most students and causes the most panic on test day. Once students understand it’s really a data interpretation exercise — not a science knowledge test — they calm down considerably. Spend real time here in prep.

Build English grammar rules. The ACT English section is a 45-question, 45-minute grammar and style test covering punctuation, sentence structure, transitions, conciseness, and organization. These rules are very learnable — direct instruction on ACT-specific grammar patterns pays off significantly.

Practice the pacing above everything else. The ACT is a speed test as much as anything. Students who haven’t drilled pacing often run out of time on the Math section (60 questions in 60 minutes) or the Reading section (40 questions in 35 minutes). Timed practice is non-negotiable.

Know the Math section’s extra topics. If your student hasn’t covered trigonometry yet, they should know that several ACT Math questions will involve trig. They won’t need deep knowledge — just the basics of sine, cosine, tangent, and right triangle relationships — but walking in without any exposure means leaving points on the table.

Take multiple full practice tests. One practice test is not enough. Take at least three full-length, timed ACT practice tests before the real thing. The first tells you where you are. The second shows whether your prep is working. The third builds the stamina and confidence to perform on test day.

How We Can Help

At Georgia Mountain Academy, we offer targeted ACT prep and SAT prep — separately or as a combined program if your student wants to try both. We start every student with a diagnostic assessment to figure out where they stand, then build a prep plan around their specific strengths and gaps.

Our ACT prep is available as a 4-week intensive group course (maximum 4 students — we keep it small on purpose) or as individual tutoring sessions. Both options include practice tests, targeted instruction, and personalized feedback.

Follow us on Facebook or email us to get on our notification list for upcoming sessions.
