AP Review Book Help?

<p>Hello everyone,</p>

<p>I'm taking AP Spanish Lang, AP Eng Lang, APUSH, and AP Chem next year.
I was wondering two things:</p>

<p>1) Is it worth buying a review book for any of these subjects (I already have one for APUSH)</p>

<p>2) If so, which brand is best? </p>

<p>I'me taking AP Bio and AP Euro this year, and I found that the Biology review book has been kidna pointless as far as help while the AP Euro one has been pretty useful, hence the previous purchase of the APUSH book. </p>

<p>Any input would be helpful! Thanks in advance!</p>
