How we scored them
The Shelf Score weighs fit, contents and edition quality. None of the listings state a warranty.
| Book | Shelf Score | Fit /35 | Contents /25 | Value /25 | Age/level /10 |
|---|---|---|---|---|---|
| Official ACT Guide 2025-26 | 9.7 | 30 | 21 | 20 | n/a |
| Kaplan Total Prep 2026-2027 | 9.6 | 29 | 20 | 20 | n/a |
| ConquerMinds ACT Prep | 9.6 | 28 | 20 | 20 | n/a |
Scores run from 9.2 to 9.8: each book’s point total is placed on that range, so more points always means a higher score. Reading age or level counts on a list where at least one listing gives one, and a book whose listing gives none then scores zero on it. Where no listing gives one, the score is taken over the other 85 points. Books carry no warranty, so warranty is not scored.
