how can i prepare for the act

<p>i'm currently a sophomore in high school. I want to get at least 30 or higher on the act. i haven't taken any real practice test yet. i only took the plan test in which all sophomores had to take. although i'm taking honors classes, i personally don't find the classes very hard( the homework load is less) so how many hours should i study every week ? and weekends? plz give me some advice. i'm really weak in math,english, and science. when i took the plan test, i thought the reading portion was the easiest and thought the other sections were hard especially the science and math sections.what books should i purchase that will help me?</p>
