Digital Reading is the same 36 questions in 40 minutes, on a screen you scroll. Line references still work; your finger on paper does not. Format choice is in digital or paper.
Keep your place with tools
Highlighter marks a sentence you will return to, in the highlighter. Line reader isolates one row of text, in the line reader.
Practice that surface before test day, in practice in your test format.
The bottom line
Same passages, different surface. Train scrolling and tools, not only paper timing.
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.
