Here are some useful websites for you:
Online Caesar Grammatical Appendix that goes with your textbook!
Caesar Textbook: If you would like your very own copy of the Caesar textbook (so you don't have to carry one with you every day), you may order one from Bolchazy-Carducci Publishers by clicking here or from Amazon by clicking here.
NOTE ON USING ENGLISH TRANSLATIONS TO HELP YOU STUDY: I do not have a problem with you using an English translation to help you get through your homework. However, I want you to use English translations in the following way: use them ONLY for guidance on figuring out the meaning or purpose of words in the sentence. DO NOT write out published translations and try to pass them off as your own!
The Latin Library: If you would like to print out a version of the Aeneid so that you can write all over it, this is the place to go. The text does not have macrons, but then again, neither does the AP exam (except for "important" ones).
Perseus Project: The Perseus Project is graciously hosted at Tufts University. On the right side of the screen (after the jump), you'll see links to the Aeneid in English and in Latin. If you click on the Latin version, you get a clickable Latin text--that means that you can click on every word and the website will parse and define it for you.
A NOTE ON THE ENGLISH VERSIONS on this site: They are antiquated and can be useful, but you may NOT write them down in your notebooks.
All Sorts of Aeneid Review Pages: All in one click! I don't know who made this site, but it is AMAZING. Contains episode-by-episode review exercises and questions as well as pages to review figures of speech, grammar, and vocabulary.
NOTE: If you scroll down on this page to Vocabulary, he has online flashcards for all the vocab used more than 24 times in the Aeneid and for the vocab that is used 12-23 times.
