Barrons literature book (and question about spanish)

<p>Are ALL the barrons books supposed to be harder than the actual test? I failed their lit diagnostic test, but got a 780 last time I took the practise from the collegeboard book. <em>confused</em> </p>

<p>Oh, and should I take the SAT II spanish after 5 years of spanish? is the curve really that bad?</p>
