Don't know where to begin? I recommend that you begin with Comenius' Vestibulum (for vocabulary) and Adler's Practical Grammar; feel free to try out other things too!
I have assigned rough levels to the texts:
BEGINNER
BEGINNER+
INTERMEDIATE
INTERMEDIATE+
ADVANCED
In the Classical Texts provided, Eutropius is easiest, followed by Caesar and Nepos.
The Latin Courses are accessible to beginners. Adler will be useful to anyone who has only studied Latin using a grammar-translation method. It has been used equally successfully by junior school students and doctoral students with many years of 'technical' Latin under their belts, but no native-type fluency in reading.
