Yes. On the enhanced ACT, Science is optional and is no longer part of your Composite score, but whether you should take it depends on your colleges and goals. Always confirm each school's requirements before deciding to skip it. A few minutes of research now can save you a lot of stress later.
What changed
The enhanced ACT centers on three required core sections, English, Math, and Reading, and makes Science a student choice. If you take Science, you receive a separate Science score plus a STEM score (Science and Math combined), but it does not move your 1 to 36 Composite. Rules can still vary by state and district contracts, so check the latest official ACT guidance for your specific test date.
How the composite works without Science
Your Composite is the rounded average of your English, Math, and Reading scores. Science, when taken, is reported on the side and feeds your STEM score rather than the Composite. Understand exactly how your test date calculates everything before you register.
When you should still take Science
Take it if your target colleges recommend or require it, if you're applying to STEM programs, or if a strong Science score could help scholarships. A good Science score can only help when schools consider it.
When skipping may be fine
If your schools explicitly don't need it and you want to focus prep on the core sections, skipping can be reasonable. But verify; don't assume. Align this with what ACT score you need for college.
Don't skip it out of fear
Many students avoid Science because it looks intimidating, but it's mostly reading and data; see is ACT Science mostly reading. With a little practice it's often a score booster, not a threat.
Decide, then prepare accordingly
Confirm your schools' policies, choose whether to take Science, and prep to match. If you take it, build skills with how to improve your ACT Science score.
Start practicing
Start with a free diagnostic, then drill your weak spots with 15-question quizzes and track how you're doing across Reading, English, and Math. Compare plans whenever you're ready to go further.
