This book helps, for the English section at least.
The 1st time I took the ACT I got a 28 in English.
I then took a Practice English test in the Real ACT Prep Book, and got a 29.
Then the 2nd time I took the ACT I got a 26 in English.
Yesterday and today I took 3 practice tests in the 1,296 ACT Practice Book and I got a 30, then a 29, then a 27.
I just took another English practice test in the Red Real ACT Book and I got a 33.
Even though my scores digressed in the
PR book, it essentially helped when I used the Real ACT Book.
Hopefully on Saturday the same improvement will show.
