Aiming for that 30+!

<p>i'm aiming for at least a 30 or higher and i need ways to attain it. i already have purchased the red book and took one practice test ....and i gotta say i need to improve on every section....english, reading and science are the sections where i need to make a major improvement on..so is there any materials and tips/ strategies you guys can give me? i would really appreciate it...btw i'm currently a sophomore and am planning to take the act in september of 2011 when i'm a junior...so i will have the whole summer to study</p>

<p>and sadly my composite act score is 21 on the first act practice test......my chances of getting into the top colleges are really low...i just don't know what to do=(</p>
