Best Prep Books

<p>Ok, spent the past hour or so poking around this forum, but I found a lot of conflicting information that I'm not sure what to do with. So I thought I'd ask here plain and simple: What, in your opinion, are the best prep books for the following tests?</p>

<p>Spanish (no listening, non-native speaker, finished 2nd class at comm. college about 2 years ago, going to take a 3rd next Spring. Preparing to take in June or so.)
US History
World History
Math II (Also planning to take it in June, going to take pre-cal at comm. college during Spring semester.)
Biology M (Taken a comm. college entry level course about 2 years ago, still have the book along with my prof's notes)</p>

<p>Thanks! =)</p>

<p>US History--Kaplans. Loved it! Helped a looot.</p>

<p>Math II--Barrons should be enough. Harder than the real test but it gets you prepared</p>
