<p>I heard that Princeton Review is the best for Spanish (it covers both test). My IB Spanish teacher recommends it to all her students that are self-studying the exam, and she has a 98% passing rate.</p>
<p>However, being in IB, we're expected to speak the language already. The book teaches how to crack the test; very little of the book actually works on the language.</p>
<p>Yeah, we used that book a lot in AP Spanish, and it was good, but it's true that the answers are not available anywhere. My teacher gave assignments out of it, and obviously she had the answers, but it's useless for self-study. The textbook we used was Una Vez M</p>
<p>her0 is right. PR is absolutely HORRIBLE. and yes arco is good for grammar. our school used tres anos and an ap spanish workbook that is posted in link above. it's pretty good practice but you want the answers. you can buy it new from barnes&noble. i have all the answers in my book :D</p>
