Raising ACT Score!

<p>Hello all, I am planning to take the ACT in June, and have taken the ACT once before with my school. My results were:
Composite: 28
English:28
Math:26
Reading:29
Science:27
I want to improve these scores to get into the 30s, and am dedicated to practicing. I was planning to take a section test everyday for all the sections starting with English, Math, and so on, and taking a practice test on Saturday mornings. Does anyone have a better plan for me to improve my score during the last 3 weeks I have until the ACT? Will taking section tests help more or doing practice problems for an hour?
I have the Red Book and 1296 PR ACT Questions. I will be using PR for the section tests and Red book for the practice tests. Please help me!</p>
