ACT reading

How do you guys manage to finish all 4 passages under the given limit? Is it advisable to split them apart and time separately?

In addition, just curious about the order of passages you guys do…I usually leave the dual passage one last, but other than that, what order do you follow?

I got a 24 in reading on the september act…i usually get 28 when i do practice, but the score fluctuates heavily based on different tests. My composite of 30–it was the reading that brought my score down significantly.

Any tips or advice? October testing is my last chance. is it possible to raise it to a 32 and above?
