How much ACT preparation is needed? What did you do to prepare?

<p>I am currently taking SAT prep classes because where I live, the SAT is more commonly accepted and because I simply need to raise my scores a whole lot. If I prepare for the SAT, how many practice test and how much time should I use to prepare for the ACT? ...I am taking it in April to compare my SAT and ACT scores and figure out which one I should retake.</p>

<p>I am a junior
SAT scores as sophomore- 1230
PSAT junior year- 1510
SAT class predicted score-1530 (So far, classes and intensive studying only raised my score 20 points...?)</p>

<p>It really seems that your SAT score depends on what test your get, because one time I finished a math section before everyone in my room and I only got minus 6 out of 20 which is pretty good for my abilities.</p>

<p>So, how many practice tests should I take, If I also need to prepare for AP tests and the SAT? One a week and then during the week-go over wrong answers?</p>
