<p>Im a sophomore in HS and want to know when to stop preparing for the SATs. I just got back the Psats in October. I take the Psats again in oct of 2006 and then Sats during my Junior year. When would you suggest to begin studying (improving vocab, practice tests)? And do you have any good vocab improving books to use?</p>
<p>Summer between soph year and jnr year. Id start preparing somewhere in mid august. As for now, enjoy your your soph year until the dread of psats and sats really starts to roll around.</p>
<p>OR since junior year will be such hell you can try to ace the SAT as a sophomore and not have to worry about it junior year.</p>
<p>I never actually prepared for the tests, but it all depends on when you want to take them. I'd suggest Christmas break of Junior year or summer before Junior year. And then if you take them again later that Spring break or that summer.</p>
<p>Take them once in January or April and then again in June (after APs). If you are still not satisfied, you still have Oct.</p>
