We have a copy of the 12th edition from Barron. I wonder whether I need the latest version, 13th edition, if it were the only prep book my kid uses. She is taking AP Chem.
the 12th edition was released on September, 2014, the 13th edition was release on September, 2016. Does it make any difference?
anyone ??
Nope the test hasnt changed.The only difference you might find are the practice questions and the explanation of different concepts.
