<p>I have my Barron's book from last year, but I did all the problems and wrote all over the pages for the AB portions. Would it be a good idea to just get another prep book or maybe Barron's 12th edition so I can get practice for both AB and BC? Thanks.</p>
<p>I don’t think the Barrons book significantly changes from year to year unless the curriculum changes on CollegeBoard. I would just use your old book and a bunch of practice tests.</p>
