ACT vs. SAT: Same and/or Different

Both the ACT and SAT rely on the same skill set, so students can prep for both tests at the same time. Still, there are some important format differences that students must understand:


The New SAT has two 800-point sections, Math and Reading/Writing & Language, that add up to a possible 1600 points1

Math is divided into a calculator section and a non-calculator section. Each of these sections has multiple-choice questions and written-response questions—where kids have to write in their answers.

The ‘verbal’ part of the SAT is comprised of a reading passage section and a grammar section.

There is an optional 50-minute essay.

The lowest score you can get on either section is 200.


The ACT has four sections: Reading, Math, English (grammar), and Science. Each is scored on a scale from 1-36. When all four scores are totaled up and divided by four, you get your overall composite score from 1-36.

There is an optional 40-minute essay.

How SAT scores match up with ACT scores.

There are a number of sites that have correspondence tables for the two tests. Here is a useful one:



  • While the ACT is not as popular as the SAT around here, all colleges that take the SAT accept the ACT, too, and vice-versa.
  • The average SAT score has risen over the past few years, so some colleges may regard SAT scores a bit more skeptically than they view ACT scores.
  • If you tend to work slowly, the ACT may not be for you. The time crunch tends to be greater—more questions in less time—on the ACT.
  • The math on the SAT requires more solid Algebra II knowledge than the math on the ACT. If you prefer “school” math to “test” math, you will probably like the SAT better.
  • If you can’t live without your calculator, remember that the SAT has a no-calculator section.
  • The ACT Science section has almost nothing to do with any science you have learned in school. It’s all about reading graphs and charts. Instead of adding its own science section, the SAT has introduced charts and graphs into some reading passages.
  • The SAT essay challenges you to analyze a long passage, without expressing your own opinion, while the ACT essay asks you to pick a side in a modern controversy (for instance: Is technology helping or hurting humanity?) and argue it with examples.
  • Since many colleges use a student’s superscore (a combination of the best section scores from different test dates), it makes sense for students to decide by the fall/winter of their junior year which test they prefer—ACT or SAT—and then take that test three or four times before they apply to college.
