For the Love of ACT Science can teach graph and experiment habits if you will sit optional Science. Older printings assume a 40-question section that still matches the count— but the Composite no longer includes it.
When the book earns a slot
A college still wants Science or STEM, and official Science explanations are not enough. Strategy hub: Science strategy.
The bottom line
Buy it for optional Science skill, not for a Composite. If you skip Science, skip the book.
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.
