About the ACT

The ACT is a standardized test administered by ACT Inc., accepted by every US four-year college and university. Unlike the SAT, the ACT includes a dedicated Science Reasoning section and tests math through pre-calculus. All sections are scored on a 1–36 scale; the composite is the average of the four section scores. Optional Writing (Essay) is available but rarely required. Many students find the ACT better matches their strengths — especially STEM learners.

ACT FAQ

Is the ACT harder than the SAT?

Neither is harder — they test different skills. The ACT is faster-paced (more questions per minute) and includes Science. The SAT Math section is slightly more conceptual.

What ACT score do I need for top colleges?

For highly selective schools, aim for 33–36. The average ACT score nationally is around 20. For scholarship consideration, many state universities require 28+.

Should I take the optional ACT Writing test?

Few colleges require the Writing section. Check each school's requirements. If no target school requires it, skip it.

How is the ACT Science section different from science class?

ACT Science tests data analysis and interpretation — not biology, chemistry, or physics facts. Students who practice reading graphs and tables improve rapidly.
