<p>Does barrons 23rd edition miss a lot of stuff from newer editions? Same with 2400, 3rd version. If not, then I would much rather use those than buy new books.</p>
<p>The SAT material stays basically the same… I used Princeton Review, which I crammed the night before lol. I did just fine, even though it was an older version.</p>
<p>Typically the bulk of the material is the same–they might correct a few errors (grammatical/answers) and add in a few words.</p>
