Practice in the format you will take. Paper timing on a booklet does not train digital tools, and a laptop does not train bubbling. The choice is in digital or paper.
Match the surface
If you will read passages on a screen, practice that, in Reading on a screen. If your site is BYOD, check that laptop, in the BYOD check.
Section clocks stay the same either way, in how long the ACT is.
The bottom line
Train the format you will sit. Transfer is smaller than it feels.
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.
