The enhanced ACT made Science optional. Your composite score now averages English, Math and Reading only. That raises a simple question for every student: should you still take Science?
What changed
- The core test is English, Math and Reading, taking about 2 hours 5 minutes.
- Science is a separate, optional 40-minute section with 40 questions.
- Taking Science gives you a separate Science score and a STEM score.
When Science is worth taking
Take it if your target colleges or programs ask for it, or if you are applying to STEM programs where a strong Science or STEM score could help your application. It is also worth considering if Science is your strongest area.
When you can skip it
If your colleges don't ask for it and you are not applying to STEM programs, skipping Science gives you a shorter test day and lets you focus prep on the three sections that make up your composite.
Deciding between the ACT and SAT
Most US colleges accept both. Try a short diagnostic of each — our ACT and SAT diagnostics take a few minutes — then focus on the one that suits you. Learn more on our ACT coaching page.
