Sources other than the red book?

I know the red book is the most accurate but I need more sources for practice Over the summer. I want to save the red book for when it gets closer to September as it only has 3 tests. What are good prep books that have practices?

The third edition of the red book has 5 tests. The three you have and 2 more.

My state offered an Electronic Library and had 4 different ACT practice exams for free, and this helped me get a 35 on my second try (34 on the first). I would check if your state has anything similar.

I have started using something like that. Is it from the University Library in Texas?

@flamingo624 I used the Tennessee Electronic Library.
