<p>Is it a good book to use? Have you used it??? How do those practice tests compare to the real ones? If my original score was about a 23 as a sophomore is it possible to raise it to a 30 during junior year?</p>
<p>I used some parts of the online Sparknotes prep to review some math/english basics and to get ideas on how to approach the essay. It's decent to review but to practice for the ACT the best you should take practice tests (the official ones from the official study guide).</p>
