I found a pdf for their 2011 edition for environmental science. Someone Tell Me why i bought the 2017 one and it looks like the exact same. Is the year change a marketing gimmick?

Ps. I have yet to check the 2016 vs 2017 psychology. I’ll get back to that later.

Does barrons renew their content too? Crashcourse? Etc etc? /:slight_smile: 8-}

Unless the College Board makes a major change to an exam, any of the annual changes to any prep book are likely to be minor.
