Need a spanish book!

<p>Hi</p>

<p>I took spanish for four years at my high school. I took a placement exam and got placed into 1230 (4 credits), which is a prerequisite for 2070 (4credits). The foreign language requirements is either take 12 credits in the same language or take a 2000 level course in a language. I can take the placement exam up to two more times.</p>

<p>What kind of book is good for brushing up on grammar and practicing?</p>

<p>Thank you!</p>
