What is the required textbook?
“Wheelock’s Latin, 6th revised edition” by Frederic M. Wheelock and revised by Richard A. LaFleur. If you can only get hold of the 6th edition, that should be okay (the differences seem few at first blush). If you would like to order the 6th revised edition, it is available from Amazon (a link to same is available over there on the right if you’d like to help offset our server costs); otherwise, most of the larger bookstores should carry it.
