There is a thing called self-learning if you haven't noticed
I am doing it right now and it's been fine so far.. Other than the fact that I want to actually hear some people who knows how to speak Latin speak the language.. Here are a few websites which you may find useful:
http://www.learnlatin.tk/ - the first Latin site I came across.. can be replaced by a book
http://www.textkit.com/latin_grammar.php/ - this one is good U______U
http://www.tldownload.com/nothanx.html/ - download it but haven't tried it..
http://www.utexas.edu/courses/cc303/sounds/ - some pronounciations
Also, go to your local library.. I found a reeeeeally good one
Never liked the look of those Oxford and Cambridge ones... After you have learnt the basics and you like it, get a dictionary and start reading poetry and things
(I haven't actually done that yet.. but I can see that happening U____U)
